Abstract

In the crystal structure of the title compound, [Mn(NCSe)2(C4H4N2)2(H2O)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(H2O)2], which are connected into layers parallel to (101) by strong water–pyrimidine O—H⋯N hydrogen bonds.
