cis-Diaqua­bis­(2,2′-bipyrimidine-κ(2) N (1),N (1′))manganese(II) bis­(perchlorate) nitro­methane disolvate monohydrate

The asymmetric unit of the title compound, [Mn(C(8)H(6)N(4))(2)(H(2)O)(2)](ClO(4))(2)·2CH(3)NO(2)·H(2)O, contains one half of a cationic Mn(II) complex, a ClO(4) (−) anion, a nitro­methane solvent mol­ecule and one half-mol­ecule of water. The complex mol­ecule and the solvent water mol­ecule are located on a twofold rotation axis. In the complex, the Mn(II) ion has a distorted cis-N(4)O(2) octa­hedral coordination geometry defined by four N atoms of the two chelating 2,2′-bipyrimidine ligands and two O atoms of water mol­ecules. In the crystal, the complex cations, anions and solvent mol­ecules are linked by inter­molecular O—H⋯N, O—H⋯O and weak C—H⋯O hydrogen bonds. The ClO(4) (−) anion is disordered over two sites with a site-occupancy factor of 0.512 (12) for the major component.
