The complex Mn(im)2(4-mbo)2·H2O (im = imidazole, 4-mbo = 4-methylbenzoate) has been prepared and its structure determined by X-ray diffraction methods. Mn(II) assumes a distorted octahedral coordination geometry formed by imidazole, water molecules and 4-mbo anions. Two 4-mbo ligands bind to Mn(II) with different coordination modes, one as a monodentate and the other as a chelate. Comparison of measured Mn-O bond distances and corresponding bond angles with those of other Mn(II) complexes incorporating monodentate carboxylate ligands suggests more electrostatic interaction between the Mn and carboxyl O atoms of the title complex. The interplanar distance between parallel imidazole rings [3.470 (13) Å] is indicative of aromatic π-π stacking, whereas the distance between the parallel benzene rings of neighboring 4-mbo anions [3.761(13) Å] is a normal van der Waals contact. Extensive hydrogen bonding occurs between the complex molecules. |
