Diaqua­bis­(seleno­cyanato-κN)bis­(pyrimidine-κN)manganese(II)

In the crystal structure of the title compound, [Mn(NCSe)(2)(C(4)H(4)N(2))(2)(H(2)O)(2)], the manganese(II) cation is coordinated by two N-bonded pyrimidine ligands, two N-bonded seleno­cyanate anions and two O-bonded water mol­ecules in a distorted octa­hedral coordination mode. The asymmetric unit consists of one manganese(II) cation, located on a centre of inversion, as well as one seleno­cyanate anion, one water mol­ecule and one pyrimidine ligand in general positions. The crystal structure consists of discrete building blocks of composition [Mn(NCSe)(2)(pyrimidine)(2)(H(2)O)(2)], which are connected into layers parallel to (101) by strong water–pyrimidine O—H⋯N hydrogen bonds.
