Diaqua-bis{[1-hydr-oxy-2-(1H-imidazol-3-ium-1-yl)ethane-1,1-di-yl]bis-(hydrogen phospho-nato)}manganese(II).

ABSTRACT: In the title compound, [Mn(C(5)H(9)N(2)O(7)P(2))(2)(H(2)O)(2)], the Mn(II) atom (site symmetry ) is coordinated by four phos-pho-n-ate O atoms from a pair of partially deprotonated 1-hydr-oxy-2-(imidazol-3-yl)ethane-1,1-bis-phophonic acid ligands (imhedpH(3) (-)) and two water mol-ecules, resulting in a slightly distorted trans-MnO(6) octa-hedral geometry for the metal ion. In the ligands, the imidazole units are protonated and two of the hydr-oxy O atoms of the phospho-nate groups are deprotonated and chelate the Mn(II), thus forming the neutral mol-ecule of the title compound. The two protonated O atoms within the phospho-nate groups of one imhedpH(3) (-) ligand act as hydrogen-bond acceptors for a bifurcated hydrogen bond originating from the coordinated water mol-ecule. The phospho-nat
