(Received 30 March 2011; accepted 4 April 2011; online 7 April 2011)

The complex mol­ecule of the title compound, [Mn(C13H10N4O8)(H2O)2] or [Mn(H4pbidc)(H2O)2] (H6pbidc = 2,2′-(propane-1,3-di­yl)bis­(1H-imidazole-4,5-dicarb­oxy­lic acid), has 2 symmetry with the twofold rotation axis running through the Mn2+ cation and the central C atom of the propanediyl unit. The cation is six-coordinated by two N atoms and two O atoms from one H4pbidc2− anion and two water O atoms in a considerably distorted octa­hedral coordination. In the crystal, adjacent mol­ecules are linked through O—H⋯O and N—H⋯O hydrogen bonds into a three-dimensional network.

Comment top

Up to date, a large number of metal-organic frameworks derived from 1H-imidazole-4,5-dicarboxylic acid (H3idc) have been synthesized since it is a good linker and can be successively deprotonated to generate H2idc-, Hidc2- and idc3- anions (Ghosh et al., 2009; Liu et al., 2008; Sun & Yang, 2007). Compared with H3idc, 2,2'-(1,3-propanediyl)bis-1H-imidazole-4,5-dicarboxylic acid (H6pbidc) can provide a greater tunability of structural frameworks because of the presence of the propanediyl spacer. However, complexes derived from this ligand have been scarcely reported. In this work, through the reaction of H6pbidc with MnSO4, we obtained the title complex [Mn(H4pbidc) (H2O)2], (I).

As shown in Figure 1, the Mn2+ cation in (I) is hexacoordinated and features a distorted octahedral coordination geometry. N1, O1, N1A, O1A atoms from the tetradentate H4pbidc2- group coordinate to the cation in a chelating fashion and O5, O5A atoms from water molecules complete the coordination polyhedron. The entire complex molecule has symmetry 2. The bond angles around the Mn2+ cation significantly deviate from 90 or 180° (see supplementary material). Intramolecular O—H···O hydrogen bonds between the carboxyl/carboxylate groups stabilize the molecular configuration whereas O—H···O and N—H···O hydrogen bonds between the water molecules and carboxylate O atoms and between imidazole groups and carboxylate O atoms of adjacent molecules consolidate the crystal packing.

Experimental top

A mixture of MnSO4 (0.05 mmol), 2,2'-(1,3-propanediyl)bis-1H-imidazole-4,5-dicarboxylic (0.05 mmol), methanol (2 ml) and water (2 ml) was placed in a 25 ml Teflon-lined stainless steel vessel and heated at 433 K for 72 h, then cooled to room temperature. Light yellow crystals with good quality were obtained from the filtrate and dried in air.

Refinement top

H atoms were positioned geometrically and refined as riding atoms, with C—H = 0.97 Å, N—H = 0.86 Å and O—H = 0.85 Å, and with Uiso(H) = 1.2 Ueq(C,N,O).

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