Crystal structure of tetra-aqua-bis-(pyrimidin-1-ium-4,6-diolato-κO⁴)manganese(II).

ABSTRACT: The Mn^II 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-hydroxy-pyrimidine ligands and by four O atoms from water mol-ecules giving rise to a slightly distorted octa-hedral coordination sphere. The complex includes an intra-molecular hydrogen bond between an aqua ligand and the non-protonated N ring atom. The extended structure is stabilized by inter-molecular hydrogen bonds between aqua ligands, by hydrogen bonds between N and O atoms of the ligands of adjacent mol-ecules, and by hydrogen bonds between aqua ligands and the non-coordinating O atom of an adjacent mol-ecule.
