| Abstract: | The synthesis and some properties of the Co(II) complex with di(hydroxymethyl)phosphinic acid (HL) of the composition CoL2·2H2O are described. X-ray powder diffraction analysis confirmed the phase homogeneity of the polycrystalline sample. The crystal structure is determined by X-ray diffraction method. The Co atom is located in the center of octahedron formed by the O atoms of two ligands L and of two water molecules. The ligand L performs bidentate-chelate function and is bonded to the Co atom through the O atoms of the phosphinate group and of one alcohol group. |
