资源简介：
The coordination of Cd2+ with P(CH2OH)3 (THP) in methanol was followed by 31P and 111Cd NMR techniques. A cadmium-to-phosphine coordination ratio of 1:3 has been established, and effective kinetic parameters have been calculated. Air oxidation of THP in the presence of CdCl2 at room temperature produces coordination polymer 3∞[Cd3Cl6(OP(CH2OH)3)2] (1). The same oxidation reaction at 70 °C gives another coordination polymer, ∞[CdCl2(OP(CH2OH)3)] (2). Complexes 1 and 2 are the first structurally characterized complexes featuring OP(CH2OH)3 as a ligand that acts as a linker between Cd atoms. The addition of NaBPh4 to the reaction mixture gives coordination polymer ∞[Na2CdCl2(O2P(CH2OH)2)2(H2O)3] (3) with (HOCH2)2PO2– as the ligand. Coordination polymers 1–3 have been characterized by X-ray analysis, elemental analysis, and IR spectroscopy.
