Synthesis and characterization of cadmium complexes with phosphorylated ligands

摘要

Complexes of cadmium(II) with phosphorylated ligands were studied in the solid state. One of these ligands is phosphocreatine (HPCR), an important natural compound and the others are diisopropylphosphorylguanidine (DPG) and diisopropylphosphorylthiourea (DPT). The complexes were synthesized and characterized by elemental and thermogravimetric analyses and IR and Raman spectroscopy. The formed complexes are: [Cd(PCr)Cl]_2, Cd(DPG)Cl_2 and [Cd(DPT)_3Cl]Cl. In the HPCR and DPG complexes, Cd(II) is bound through the oxygen of the phosphoryl group and the nitrogen of the guanidine group and in the DPT complexes through the sulfur atom.
