Abstract top

In the title compound, [Mn2(C12H6O4)2(C10H14N4)(H2O)]n or [Mn2(1,4-ndc)2(L)(H2O)]n, where 1,4-ndc is naphthalene-1,4-dicarboxylate and L is 1,1'-(butane-1,4-diyl)diimidazole, the coordination polyhedron around each MnII atom is distorted octahedral. The water molecule and the L ligand are situated across a twofold rotation axis. The MnII atoms are bridged by 1,4-ndc and L ligands, forming a three-dimensional network. O-H...O hydrogen bonds are observed within the network.

Comment top

Some interesting interpenetrated or entangled metal-organic networks with bis(imidazole)-containing ligands have been documented (Yang et al., 2008). But, flexible ligands such as 1,1'-(1,4-butanediyl)bis(imidazole) (L) have not been well explored (Ma et al., 2003). In this work, we used 1,4-naphthalenedicarboxylic acid (1,4-H2ndc) and L as linkers to obtain a new coordination polymer, [Mn2(1,4-ndc)2(L)(H2O)]. We report here its crystal structure.

In the title compound, each MnII atom displays a distorted octahedral coordination sphere, completed by one N atom from one L ligand, four carboxylate O atoms from 1,4-ndc ligand and the O atom of the water molecule (Fig. 1). Both the water molecule and L ligand are situated across a twofold rotation axis. Two adjacent MnII atoms are bridged by carboxylate groups of 1,4-ndc ligands and water molecules forming a three- dimensional network containing [Mn2(1,4-ndc)2(H2O)] units. The network is further strengthened by the coordination of L ligands (Fig. 2).

Experimental top

A mixture of 1,4-H2ndc (0.5 mmol), L (0.5 mmol), NaOH (1 mmol) and MnCl2.2H2O (0.5 mmol) was suspended in 14 ml of deionized water and sealed in a 20-ml Teflon-lined autoclave. Upon heating at 413 K for 3 d, the autoclave was slowly cooled to room temperature. The crystals formed were collected, washed with deionized water and dried.

Refinement top

C–bound H atoms were positioned geometrically (C-H = 0.93–0.97 Å) and refined as riding, with Uiso(H) = 1.2Ueq(C). The water H atom was located in a difference Fourier map and refined freely.

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. 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 > 2sigma(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.
