The search for novel manganese(II) compounds having interesting magnetic properties, using 1-(pyridin-2-yl)-2-(pyridin-2-ylmethylidene)hydrazine (HL) as a tridendate ligand, led to the preparation of the title mononuclear material, [MnCl(NO₃)(C₁₁H₁₀N₄)(H₂O)], and the determination of its structure by XRD. The asymmetric unit comprises a discrete molecule in which the cation Mn^II is heptacoordinated. The environment around the cation is an almost perfect pentagonal bipyramid. The base is defined by the two N atoms of the pyridine rings, the N atom of the imino function of the ligand and the two O atoms of the chelating bidentate nitrate ligand. The apical positions are occupied by a Cl atom and a water molecule. In the crystal, there are numerous hydrogen bonds of the types Ow—H⋯ONO₂ and C—H⋯ONO₂, which generate layers parallel to the bc plane in which the ligands in the axial positions point into the interlayer space. These axial ligands give rise to hydrogen bonds of the types Ow—H⋯ONO₂, Ow—H⋯Cl, N—H⋯Cl and C—H⋯Cl, leading to a three-dimensional framework. The chain bridging the two pyridine rings is disordered over two sets of sites in a 0.53 (2):0.47 (2) ratio.

Keywords: crystal structure; manganese; Schiff base.

1. Chemical context

Although very much studied, the coordination chemistry of manganese remains very interesting as this metal can have several degrees of oxidation and its complexes can display different coordination numbers and geometries that are not always easily predicted (Chiswell et al., 1987 ; Baldeau et al., 2004 ; Mikuriya et al., 1997 ). Although the coordination numbers four and six are the most common in the coordination chemistry of manganese, the coordination numbers five, seven and eight are also observed (Louloudi et al., 1999 ). As a result of the multiple degrees of oxidation of this metal, interest in the coordination chemistry of manganese complexes is considerable. The involvement of manganese in various important biological processes such as oxidation of water by photosynthetic enzymes (Whittaker & Whittaker, 1997 ), hydrogen peroxide disproportionation by catalase (Meier et al., 1996 ), superoxide dismutase (SOD) (Schwartz et al., 2000 ), ribonucleotide reductase and lipoxygenase (Baffert et al., 2003 ) increases the interest of scientists in this metal. These examples from nature inspire chemists to search for bio-mimetic catalysts of these metalloenzymes that are highly selective and cause little damage to the environment (Krishnan & Vancheesan, 1999 ). Manganese complexes are also used as catalysts in many processes such as epoxidation of alkene (Castaman et al., 2009 ), oxidation (Wegermann et al., 2014 ) and hydrogenation of ketones (Bruneau-Voisine et al., 2017 ). The involvement of the metal center in these processes depends as much on its degree of oxidation as on its coordination number in the complex. The synthetic procedures adopted are essential for yielding complexes with specific properties. In this context, for the synthesis of the heptacoordinated Mn^II title complex, we use a one-pot synthesis method, which is an efficient approach to prepare a large variety of coordination compounds (Oyaizu et al., 2000 ). Manganese dichloride tetrahydrate is mixed with the synthesized organic ligand (HL), which provides three soft nitrogen-binding sites in the presence of nitrate anions that can act with hard oxygen-binding sites to yield a mononuclear heptacoordinated manganese(II) complex.

2. Structural commentary

The structure of the title complex is shown in Fig. 1. The asymmetric unit comprises a discrete molecule in which the cation Mn^II is heptacoordinated. The coordination polyhedron of the Mn^II center is best described as a distorted pentagonal bipyramid with an MnN₃O₃Cl chromophore. The basal plane is occupied by two nitrogen atoms from the pyridine rings, one nitrogen atom from the imino function and two oxygen atoms from the chelating bidentate nitrate group. The metal-bound ligand nitrogen atoms exhibit angles of 69.85 (7)° (N1—Mn1—N2) and 69.62 (7)° (N2—Mn1—N4) which are slightly different from the ideal angle for a regular pentagon (72°). The sum of the equatorial angles around Mn^II is 359.72°. The angle formed by the atoms in axial positions around Mn^II [Cl1—Mn1—O1W = 179.07 (4)°] is very close to the ideal value of 180°. The Mn—O/N bond lengths (Table 1) are longer than those observed in the heptadentate manganese complex [Mn(L)(NO₃)₂] [L is 2,6-bis(1-butyl-1H-benzo[d]imidazol-2-yl)pyridine; Kose & McKee et al., 2014 ]. The apical bond Mn1—Cl1 [2.4999 (6) Å] is the longest and is comparable to those found for the complex [Mn(L)(Cl)₂]·MeOH [Mn1—Cl1 = 2.4849 (7), Mn1—Cl2 = 2.5465 (7) Å] {L is 2,6-bis[(2-hydroxyphenylimino)methyl]pyridine; Kose et al., 2015 }. The second axial bond is the shortest distance in the structure [Mn1—O1W = 2.2239 (14) Å]. The two pyridine rings are connected by a disordered chain C—CH=N—NH—C in which the bond lengths are slightly different from those observed in similar complexes; this may be related to the observed disorder. Two intramolecular hydrogen bonds, C1—H1⋯O2 and C11—H11⋯O3, are also observed in the structure (Table 2, Fig. 1).

3. Supramolecular features

In the crystal, the complex molecules are linked by hydrogen bonds, giving rise to a three-dimensional network (Fig. 2, Table 2). The structure is built up from pentagonal bipyramids around the Mn^II atom, which are assembled in layers parallel to the bc plane. These layers are interconnected by hydrogen bonds. The coordinating axial water molecule points into the interlayer space and act as a hydrogen-bond donor towards oxygen atom O2-NO₂ and chlorine atom Cl1 (Fig. 2) via the hydrogen bonds O1W—H1WB⋯O2ⁱⁱ and O1W—H1WA⋯Cl1ⁱ, [symmetry codes: (i) x + 1, y, z; (ii) −x + 2, −y + 1, −z + 2]. The axial Cl1 atom points also in the interlayer space and acts as a hydrogen-bond acceptor toward N3—H3N⋯Cl1ⁱⁱⁱ and C6—H6⋯Cl1ⁱⁱⁱ [symmetry code: (iii) −x + 1, −y + 1, −z + 1]. The combined hydrogen bonds link the layers into a three-dimensional framework. Within a layer, the molecules are interconnected by hydrogen bonds of the type C—H⋯ONO₂ [C8—H8⋯O4^iv—NO₂; symmetry code: (iv) x, y, z − 1].

4. Database survey

The ligand 1-(2-pyridyl)-2-(pyridin-2-ylmethylidene)hydrazine has been widely used in coordination chemistry. The current release of the CSD (Version 5.39, last update Nov 2017; Groom et al., 2016 ) affords 22 hits. Seven examples of complexes with the above ligand with f-block metal ions appear in the literature (Baraniak et al., 1976 ; Ndiaye-Gueye, Dieng, Thiam, Sow et al., 2017 ; Ndiaye-Gueye, Dieng, Thiam, Lo et al., 2017 ; Ndiaye-Gueye, Dieng, Lo et al., 2017 ; Gueye et al., 2017 ). The other entries are for complexes with p- and d-block metal ions. Structures are available for Ca^II (Vantomme et al., 2014 ), Cu^II (Mesa et al., 1988 , 1989 ; Rojo et al., 1988 ; Ainscough et al., 1996 ; Chowdhury et al., 2009 ; Mukherjee et al., 2010 ; Chang et al., 2011 ), Co^II (Gerloch et al., 1966 ), Ni^II (Chiumia et al., 1999 ) and Zn^II (Dumitru et al., 2005 ; Vantomme et al., 2014 ). In all cases, the ligand behaves as a tridentate ligand acting through the soft nitrogen donor atoms from the two pyridine rings and the imino function. The hard protonated nitrogen atom remains uncoordinated in all complexes.

5. Synthesis and crystallization

A mixture of 2-hydrazinopyridine (1 mmol) and 2-pyridinecarbaldehyde (1 mmol) in ethanol (10 mL) was stirred under reflux for 30 min. A mixture of ammonium nitrate (3 mmol) and MnCl₂·4H₂O (1 mmol) in ethanol (10 mL) was added to the solution. The mixture was stirred for 30 min and the resulting yellow solution was filtered and the filtrate was kept at 298 K. A yellow powder appeared after one day and was collected by filtration, yield 65%. Analysis calculated for [C₁₁H₁₂ClMnN₅O₄] C, 32.41; H, 3.26; N, 22.67. Found: C, 32.37; H, 3.19; N, 22.60%. μ_eff(μ_B): 5.98 Λ_M (S cm² mol⁻¹): 14. IR (cm⁻¹): 3233, 1609, 1560, 1521, 1465, 1422, 1289, 1148, 776, 673.

6. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 3. All H atoms (=CH, NH and OH₂ groups) were optimized geometrically (C—H = 0.93, N—H = 0.86 and O—H = 0.87–0.91 Å) and refined as riding with U_iso(H) = 1.2U_eq(C) or 1.5U_eq(O). The chain bridging the two pyridine rings is disordered. This disorder may be explained by the fact that the sequence of atoms C(Py)—CH=N—NH—C(py) overlaps with the sequence C(py)—NH—N=CH—C(py), meaning two orientations of the ligand. In such a case, for the refinement it was assumed that the C atom of the CH group from one chain and the NH atoms from the second chain occupy the same position. The same relates inversely. The occupancy factor refined to 0.53 (2):0.47 (2).

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.
