cis-Tetraaquabis{5-[4-(1H-imidazol-1-yl-κN3)phenyl]tetrazolido}manganese(II) dihydrate

Abstract

In the title compound, [Mn(C10H7N6)2(H2O)4]·2H2O, the Mn2+ lies on a twofold rotation axis and is six-coordinated by two N atoms from the cis-related monodentate 5-[4-(imidazol-1-yl)phenyl]tetrazolide ligands and four O atoms from the coordinated water molecules. The complex molecules are connected via water O—H...O and O—H...N hydrogen bonds and weak π–π stacking interactions between the benzene rings [minimum ring centroid separation = 3.750 (6) Å] into a three-dimensional polymeric structure. The imidazolyl group of the ligand is partially disordered over two sets of sites with refined occupancies of 0.531 (7):0.469 (7).
