Synthesis and characterization of cadmium complexes with phosphorylated ligands

Complexes of cadmium(II) with phosphorylated ligands were studied in the so lid state. One of these ligands is phosphocreatine (HPCR), an important nat ural compound and the others are diisopropylphosphorylguanidine (DPG) and d iisopropylphosphorylthiourea (DPT). The complexes were synthesized and char acterized by elemental and thermogravimetric analyses and IR and Raman spec troscopy. The formed complexes are: [Cd(PCr)Cl](2), Cd(DPG)Cl-2 and [Cd(DPT )(3)Cl]Cl. In the HPCR and DPG complexes, Cd(II) is bound through the oxyge n of the phosphoryl group and the nitrogen of the guanidine group and in th e DPT complexes through the sulfur atom.
