Crystal structure of tetraaquabis(pyrimidin-1-ium-4,6-diolato-κO 4)manganese(II)
نویسندگان
چکیده
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-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.

The title salts, C8H13N4 (+)·Cl(-), (I), and C8H13N4 (+)·NO3 (-), (II), contain linked pyridinium-piperazine heterocycles. In both salts, the piperazine ring adopts a chair conformation with protonation at the N atom not linked to the other ring. In the crystal of (I), weak N-H⋯Cl inter-actions are observed, leading to zigzag chains along [100]. In the crystal of (II), both H atoms on the NH2 (...
