title: cis-Tetra-aqua-bis-{5-[4-(1H-imidazol-1-yl-κN(3))phen-yl]tetra-zolido}manganese(II) dihydrate.
abstract: In the title compound, [Mn(C(10)H(7)N(6))(2)(H(2)O)(4)]·2H(2)O, the complex unit comprises an Mn(2+) ion, coordinated by two imidazole N atoms from cis-related monodentate 5-[4-(imidazol-1-yl)phen-yl]tetra-zolide ligands and four water mol-ecules, together with two water mol-ecules of solvation. The Mn(2+) ion lies on a twofold rotation axis and has a slightly distorted octa-hedral geometry. The mol-ecules are connected by O-H⋯N and O-H⋯O hydrogen bonds involving both coordinated and solvent water mol-ecules, generating a three-dimensional structure. Two C atoms of the imidazole ring of the ligand are each disordered over two sites with occupancy factors of 0.75 and 0.25.
