文摘

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_{鈭?/sub>[Cd3Cl6(OP(CH2OH)3)2] (1). The same oxidation reaction at 70 掳C gives another coordination polymer, 鈭?/sub>[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 鈭?/sub>[Na2CdCl2(O2P(CH2OH)2)2(H2O)3] (3) with (HOCH2)2PO2^{鈥?/sup> as the ligand. Coordination polymers 1鈥?b>3 have been characterized by X-ray analysis, elemental analysis, and IR spectroscopy.}}
