The solution-mediated syntheses and crystal structures of catena-poly[bis(2-amino-3-hydroxypyridinium) [zinc-di-μ-phosphonato] dihydrate], {(C₅H₇N₂O)[Zn(HPO₃)₂]·2H₂O}_n, (I), and poly[(benzene-1,2-diamine)(μ₅-phosphonato)zinc], [Zn(HPO₃)(C₆H₈N₂)]_n, (II) are described. The extended structure of (I) features [010] anionic chains of vertex-sharing ZnO₄ tetrahedra and HPO₃ pseudopyramids; these chains are characterized by disorder over major [occupancy 0.7962 (13)] and minor [0.2038 (13)] components, which can be superimposed on each other by a nominal translational shift. The 2-amino-3-hydroxypyridinium cations and water molecules of crystallization interact with the ZnPO chains by way of numerous O—H⋯O and N—H⋯O hydrogen bonds. The structure of (II) features a direct Zn—N bond to the neutral 1,2-diaminobenzene species as part of ZnO₃N tetrahedra as well as HPO₃ pseudopyramids. The Zn- and P-centred groupings are linked through their O-atom vertices into infinite (010) sheets and the structure is consolidated by N—H⋯O hydrogen bonds and N—H⋯π interactions. The crystal of (I) chosen for data collection was found to be an inversion twin in a 0.56 (2):0.44 (2) domain ratio.

Keywords: zinc phosphite; ligand; template; disorder; crystal structure.

1. Chemical context

Organically templated zinc phosphites (ZnPOs) are a well-established family of organic/inorganic open frameworks (e.g. Harrison et al., 2001 ; Dong et al., 2015 ; Huang et al., 2017 ). The stated motivations for studying these phases include their potential applications in catalysis, separation and as `functional materials' (Wang et al., 2003 ). Important features of their crystal structures include the nature of the polyhedral building units [ZnO₄, ZnO₃(H₂O), ZnO₃N, HPO₃] and their connectivity, which defines the Zn:P ratio; for example, ZnO₄ and HPO₃ units sharing all their vertices as Zn—O—P bonds will lead to an anionic [Zn₃(HPO₃)₄]_n²ⁿ⁻ framework (a 3:4 Zn:P ratio), the charge of which must be balanced by the organic templating cation (e.g. Katinaitė & Harrison, 2017 ). If, however, one of the P—O vertices is `terminal' (a formal P=O double bond that does not link to zinc), then a [Zn(HPO₃)₂]_n²ⁿ⁻ stoichiometry (1:2 Zn:P ratio) arises (e.g. Halime et al., 2011 ). A combination of HPO₃ (all vertices bonding) and HPO₃ (one terminal vertex) units leads to a [Zn₂(HPO₃)₃]_n²ⁿ⁻ framework (2:3 Zn:P ratio) (Lin et al., 2004a ). Another important structural feature of these phases is the `dual character' of the organic species: most commonly it is a protonated organic amine, which interacts with the ZnPO framework via N—H⋯O hydrogen bonds (e.g. Harrison & McNamee, 2010 ). However, direct Zn—N bonds are also possible (e.g. Fan et al., 2005 ), in which case the (unprotonated) organic species could be said to be acting as a ligand, although its steric bulk means that it does exert a `templating effect' on the extended structure. This has an important effect on the zinc-to-phosphorus ratio; for example, a combination of ZnO₃N and HPO₃ (all vertices bonding) units leads to a neutral [Zn(HPO₃)]_n (1:1 Zn:P ratio) network (e.g. Lin et al., 2004b ). The complex structure of {(C₄H₁₂N₂)[Zn₅(HPO₃)₆(C₄H₁₀N₂)]}_n (Harrison, 2006 ) is notable for featuring the same organic species acting as a protonated template and a ligand in the same structure.

As part of our ongoing studies in this area we now describe the syntheses and structures of (C₅H₇N₂O)[Zn(HPO₃)₂]·2H₂O, (I), and [Zn(HPO₃)(C₆H₈N₂)], (II), where C₅H₇N₂O⁺ is the 2-amino-3-hydroxypyridinium cation and C₆H₈N₂ is neutral 1,2-diaminobenzene (also known as o-phenylenediamine).

2. Structural commentary

Compound (I) features unusual disorder of the zincophosphite component of the structure, in a 0.7962 (13):0.2038 (13) ratio for the major and minor components, respectively. The major component features two zinc atoms (Zn1 and Zn2), four phosphorus atoms (P1–P4) and 12 oxygen atoms (O1–O12), the latter being parts of pseudo-pyramidal HPO₃²⁻ hydrogenphosphite anions (Fig. 1). Both zinc ions adopt typical tetrahedral coordination geometries to four nearby O atoms (which all bridge to an adjacent P atom) with mean Zn—O separations of 1.939 and 1.937 Å for Zn1 and Zn2, respectively. The ranges of O—Zn—O bond angles for Zn1 [101.6 (3)–126.2 (3)] and Zn2 [102.1 (3)–125.8 (3)°] seem to indicate a high degree of distortion from a regular tetrahedral geometry for these polyhedra, but these data should be approached with caution because of the disorder of the ZnPO framework (vide infra). The P atoms in (I) all display their expected tetrahedral geometries to three O atoms (two of which bridge to Zn atoms and one is `terminal', hence the 1:2 Zn:P stoichiometry) and one H atom. As usual (Harrison, 2011 ) the H atom attached to the P atom does not show any propensity to form hydrogen bonds. The mean P—O separation for the terminal vertices (1.510 Å) is slightly shorter than the corresponding value for the bridging O atoms (1.538 Å), although there is some overlap of individual values. The O—P—O bond angles in (I) are clustered in the narrow range of 111.0 (4)–113.8 (4)° (mean = 112.5°) and are comparable to those in related structures (e.g. Dong et al., 2015). For the oxygen atoms (O1–O12) associated with the major disorder component, the mean Zn—O—P angle is 129.6° (Table 1); four of these O atoms (O3, O6, O9 and O12) are parts of the terminal P=O vertices. The geometrical data for the minor disorder component of the chain (atoms Zn11, Zn12, P11–P14, O21–O28) are broadly similar to those of the major component, although their precision is about four to five times lower.

A striking feature of the disorder as modelled here is that atoms O1, O4, O7 and O10 are common to both major and minor components (i.e. they were modelled with full occupancies). These atoms are involved in the most distorted bond angles [e.g. O1—Zn1—O4 = 126.2 (3)°] and their mean U_iso value of 0.0191 is notably higher than the corresponding value of 0.0146 Å² for the major-disorder O atoms. This may indicate that there are actually separate, adjacent, sites for the major and minor components for these O atoms but they cannot be resolved from the present data.

The polyhedral connectivity in (I) leads to [010] infinite anionic four-ring [Zn(HPO₃)₂]_n²ⁿ⁻ chains of strictly alternating vertex-sharing ZnO₄ and HPO₃ groups with only translational symmetry building up the chains. Fig. 2 shows a fragment of a chain including both disorder components in which it may be seen that one can be superimposed on the other by means of a simple translation of approximately b/2. Each disorder component of the chain has four crystallographically unique water molecules of crystallization associated with it (O1w–O4w and O11w–O14w for the major and minor disorder components, respectively) and all of them form two O—H⋯O hydrogen bonds to their adjacent chains.

The structure of (I) is completed by four unique, ordered, charge-balancing C₅H₇N₂O⁺ cations, with each one protonated at its pyridine N atom rather than the amine group as always appears to be the case with this species (e.g. Stilinović & Kaitner, 2011 ). Each cation in (I) features an intramolecular N—H⋯O hydrogen bond (Table 2) from the 2-amino group to the adjacent 3-hydroxy moiety, generating an S(5) ring in each case. In the extended structure, each cation forms numerous N—H⋯O and O—H⋯O hydrogen bonds with chain and water O atoms from both disorder components acting as acceptors. The situation for the N1 cation is illustrated in Figs. 3 and 4 for the major and minor disorder components of the chain, respectively. A view down [010] of the packing for (I) (Fig. 5) shows the anionic chains interspersed by the organic cations, which themselves form wavy (001) sheets.

The structure of (II) consists of ZnO₃N tetrahedra and HPO₃ pseudo pyramids as well as neutral 1,2-diaminobenzene molecules (Table 3, Fig. 6). The Zn—N bond, which is notably longer than the Zn—O vertices (mean = 1.935 Å) arises from a direct bond to the organic species, which could be said to be acting as a ligand rather than a (protonated) templating agent. The Zn- and P-centred polyhedra are linked by O atoms (mean Zn—O—P angle = 133.0°) and there are no terminal O atoms. This `3+3' bonding mode naturally leads to the 1:1 Zn:P stoichiometry in (II).

The extended structure of (II) contains (010) sheets of strictly alternating Zn- and P-centred polyhedra incorporating very contorted six-ring windows (Fig. 7). The pendant organic molecules protrude either side of the sheets (Fig. 8). The structure of (II) is consolidated by N—H⋯O hydrogen bonds, which are absolutely typical in this family of phases (Huang et al., 2017) and less common N—H⋯π interactions (Table 4). All of these bonds are intra-sheet interactions and no directional inter-sheet interactions beyond normal van der Waals contacts could be identified, the shortest of these being H3⋯H4 (2.67 Å).

3. Database survey

So far as we are aware, no zincophosphites with either of the organic species described here have been reported previously. It may be noted that the C₆H₇N₂O⁺ cation in (I) has been reported as a counter-ion with simple, discrete MCl₄²⁻ anions where M = Co (Koval'chukova et al., 2008 ) and Cu (Halvorson et al., 1990 ) and with polymeric two-dimensional copper/bromide networks (Place et al., 1998 ). A structure containing Zn—N bonds related to (II) featuring the isomeric 1,4-diaminobenzene species has been described (Kirkpatrick & Harrison, 2004 ). In this compound, the diamine bonds to zinc atoms from both its N atoms and acts as a `pillar' linking ZnPO sheets into a three-dimensional framework. A survey of of the Cambridge Structural Database (Groom et al., 2016 : updated to April 2018) for zinc phosphite frameworks with a directly bonded ligand/template (i.e. those containing a N—Zn—O—P—H fragment) revealed 21 matches.

4. Synthesis and crystallization

Compound (I) was prepared from 1.00 g ZnO, 2.00 g H₃PO₃ and 1.35 g 2-amino-3-hydroxypyridine. These components were added to a PTFE bottle containing 20 ml of water and shaken well, to result in an off-white slurry. The bottle was sealed and placed in an oven at 353 K for 48 h and then removed to cool to room temperature. Product recovery by vacuum filtration yielded a mass of pale-brown laths of (I).

To prepare (II), 1.00 g zinc acetate, 0.74 g H₃PO₃, 0.99 g 1,2-diaminobenzene and 20 ml of water were placed in a PTFE bottle and shaken well, to result in a brown slurry. The bottle was sealed and placed in an oven at 353 K for 48 h and then removed to cool to room temperature. Product recovery by vacuum filtration yielded a few colourless blocks of (II) accompanied by unidentified dark-brown sludge.

5. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 5. The structure of (I) proved to be difficult to solve and refine. The systematic absences pointed to space group P2₁/n but no chemically reasonable models could be established in this centrosymmetric space group. Lower symmetry space groups were then tried and a plausible model in Pn was developed, as the complex nature of the disorder of the chain became apparent. In the early stages of the refinement, site occupancies were freely varied to establish which atoms belonged to which disorder component; the occupancies for O1, O4, O7 and O10 barely varied from unity and were fixed as fully occupied. When the disorder model was becoming clear, constrained refinements of site occupancies for the major and minor disorder components (including their associated water molecules of crystallization) led to refined values of 0.7962 (13):0.2038 (13). The structure of (II) was solved and refined without difficulty.

For (I), the H atoms associated with the P atoms were located in difference maps, relocated to idealized positions (P—H = 1.32 Å) and refined as riding atoms. The N- and O-bound H atoms of the cations were located in difference maps and refined as riding atoms in their as-found relative positions. Most of the water H atoms were located in difference maps and refined in a similar fashion; the remainder were placed geometrically to form reasonable hydrogen bonds and refined as riding atoms. The C-bound H atoms were placed geometrically (C—H = 0.95 Å) and refined as riding atoms. In every case, the constraint U_iso(H) = 1.2U_eq(carrier) was applied. The crystal of (I) chosen for data collection was found to be an inversion twin in a 0.56 (2):0.44 (2) domain ratio.

For (II), the phosphite H atom was located in a difference map, relocated to an idealized position (P—H = 1.32 Å) and refined as a riding atom. The N-bound H atoms were located in difference maps and their positions were freely refined. The C-bound H atoms were placed geometrically (C—H = 0.95 Å) and refined as riding atoms. The constraint U_iso(H) = 1.2U_eq(carrier) was applied to all H atoms.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refined as a 2-component inversion twin
