A novel two-dimensional→three-dimensional Cu^II coordination polymer, {[Cu₂(C₁₀H₁₄N₄)₅](NO₃)₄·4H₂O}_n, based on the 1,1′-(butane-1,4-diyl)bis(1H-imidazole) (biim) ligand and containing one crystallographically unique Cu^II atom, has been synthesized under hydrothermal conditions. The Cu^II atom is coordinated by five N atoms from biim ligands, one of which has crystallographically imposed inversion symmetry, giving rise to a slightly distorted CuN₅ square-pyramidal geometry. The Cu^II cations are linked by biim ligands to give a 4⁴ layer; the layers are further bridged by biim ligands, generating a double sheet with a thickness of 14.61 Å. The sheet features rhombic Cu₄(biim)₄ windows built up from four Cu^II centers and four biim ligands with dimensions of 14.11 × 14.07 Å². Each window of a layer is penetrated directly by the biim ligand of the adjacent net, giving a two-dimensional→three-dimensional entangled framework.

Keywords: crystal structure; Cu^II complex; 1,1′-(1,4-butane-1,4-diyl)bis(1H-imidazole); three-dimensional coordination polymer.

1. Chemical context

In the past decade, entangled systems of metal–organic frameworks (MOFs) have attracted great attention because of their undisputed aesthetic topological structures, fascinating properties and applications, such as molecular machines and sensor devices, and potential biological applications (Carlucci et al., 2003a ; Bu et al., 2004 ; Batten & Robson, 1998 ; Perry et al., 2007 ; Yang et al., 2012 ; Baburin et al., 2005 ; Blatov et al., 2004 ). Currently, many chemists are making great contributions to this field, and a number of compounds with entangled framework structures have been synthesized and characterized, which are based on N-donor ligands due to their diversity in coordination modes and their versatile conformations (Murphy et al., 2005 ; Wu et al., 2011a ; Yang et al., 2008 ; Zhang et al., 2013 ). However, the controlled synthesis of crystals with entangled framework structures is still a significant challenge, although many entangled coordination compounds of this sort have already been obtained (Carlucci et al., 2003b ; Batten, 2001 ; Wu et al., 2011b ). According to previous literature, the construction of MOFs mainly depends on the nature of the organic ligands, metal ions, the temperature, the pH value, and so on (James, 2003 ; Chen et al., 2010 ; Ma et al., 2004 ).

Recently, 1,1′-(1,4-butanediyl)bis(imidazole) and carboxylate ligands have frequently been employed in the construction of coordination compounds due to their flexible character, and coordination compounds displaying different structural motifs have been reported (Wen et al., 2005 ; Chen et al., 2009 ; Dong et al., 2007 ). However, the syntheses of complexes based on inorganic ions have been scarcely been reported.

It is interesting to note that the Cu^II complexes based on inorganic counter-ions and the biim ligand, [Cu(biim)₂(H₂O)]Cl₂·5H₂O (II), [Cu(biim)₂(H₂O)](NO₃)₂·H₂O (III) and [Cu(biim)₂]SO₄·8H₂O (IV), were synthesized at room temperature (Ma et al., 2004). In (II), (III) and (IV), the Cu^II cations are bridged by biim ligands, forming infinite 4⁴ networks that contain 44-membered rings. It is worth mentioning that no interpenetration occurs in (II) and (III), while in (IV), two 4⁴ networks are interpenetrated in a parallel fashion, forming a two-dimensional →two-dimensional sheet. In the present work, we describe the synthesis and structure of one such entangled Cu^II complex, the title compound (I), [Cu₂(C₁₀H₁₄N₄)₅](NO₃)₄·4H₂O, which exhibits a novel two-dimensional→three-dimensional polymeric structure, and which was prepared under hydrothermal conditions instead of at room temperature.

2. Structural commentary

The structure of compound, (I) (Fig. 1), contains one Cu^II, two and one half biim ligands, two nitrate ions and two water molecules per asymmetric unit. The Cu^II cation is five-coordinated and exhibits a distorted CuN₅ square-pyramidal coordination geometry from the biim ligands (Table 1). The cis basal N—Cu—N bond angles range from 88.42 (15) to 90.72 (15)°, and the apical bond angles from 92.02 (14) to 101.23 (15)°.

3. Topological features

The Cu^II cations are linked by biim ligands, giving a 4⁴ layer; the layers are further bridged by biim ligands at nearly vertical directions, generating a double sheet with a thickness of 14.61 Å (Fig. 2). The sheet exhibits Cu₄(biim)₄ windows built up from four Cu^II atoms and four biim ligands with dimensions of 14.11 × 14.07 Å². From a topological viewpoint, the sheet reveals a 5-connected topology, in which the Cu atom acts as a 5-connected node and the biim ligand is regarded as a linker. Considering the composition, the Schläfli symbol of the two-dimensional network can be defined as 4⁸.6² (Fig. 3).

It is noteworthy that every Cu₄(biim)₄ unit of each layer is threaded through simultaneously by the biim ligand from an adjacent layer in a parallel fashion, forming a two-dimensional→three-dimensional entangled framework, as highlighted in Fig. 4. All sheets are identical, and all the Cu₄(biim)₄ windows are equivalent. As far as we know, so far only a few examples of two-dimensional→three-dimensional entangled structures have been observed: the networks in these are mainly focused on 4⁴ and 6³ topologies. Two-dimensional→three-dimensional entangled frameworks with 4⁸.6² topology have scarcely been reported.

Figure 4
The two-dimensional→three-dimensional framework in (I)

It should be pointed out that although the starting materials used for syntheses of (I) and the related compound (III) are the same, their complex structures are entirely different (Ma et al., 2004). The structure of (III) can be symbolized as a 4⁴ net, and has no interpenetration. Although it is hard to propose definitive reasons as to why compounds (I) and (III) adopt different configurations, it can be speculated that pH values and temperature may exert an important influence on the resulting architectures.

4. Synthesis and crystallization

A mixture of biim (0.057 g, 0.3 mmol), Cu(NO₃)₂·3H₂O (0.048 g, 0.2 mmol) and water (15 ml) was mixed and stirred at room temperature for 10 min. The mixture was adjusted with 1 M HNO₃ to pH ≃ 5 and then sealed in a 25 ml Teflon-lined autoclave and heated at 443 K for three days. Then the mixture was cooled to room temperature, and black–blue crystals of (I) were obtained in 56% yield based on Cu^II. Elemental analysis, found: C 42.85, N 24.14, H 5.56%; calculated for C₂₅H₃₉CuN₁₂O₈ (M_r = 699.22): C 42.94, N 24.04, H 5.62%.

5. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2. All H atoms bonded to C atoms were positioned geometrically and refined as riding atoms,with C—H distances of 0.93 (aromatic) or 0.96 Å (CH₂) with U_iso(H) = 1.2U_eq(C). H atoms bonded to O atoms were located from difference maps, refined with O—H = 0.84 (1) and H⋯H = 1.40 (1) Å and with U_iso(H) = 1.5U_eq(O). One NO₃ group was highly disordered and could not be modelled successfully (geometries, adp's). After using the SQUEEZE (Spek, 2014 ) routine of PLATON (Spek, 2009 ), refinement converged smoothly.

Special details top

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

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > 2σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
