摘要

The MnII ion in the structure of the mononuclear title compound, Mn(C4H3N2O2)2(H2O)4, is situated on an inversion center and is coordinated by two O atoms from two deprotonated 4,6-di#173;hydroxy#173;pyrimidine ligands and by four O atoms from water mol#173;ecules giving rise to a slightly distorted octa#173;hedral coordination sphere. The complex includes an intra#173;molecular hydrogen bond between an aqua ligand and the non-protonated N ring atom. The extended structure is stabilized by inter#173;molecular hydrogen bonds between aqua ligands, by hydrogen bonds between N and O atoms of the ligands of adjacent mol#173;ecules, and by hydrogen bonds between aqua ligands and the non-coordinating O atom of an adjacent mol#173;ecule.
