Four new complexes [L2Cu(S2COC2H5)] L=PPh3 (A), C3H4N2 (B)}, [L2IrCl2(S2COC2H5)] (L=PPh3) (C) and [L2Pd(S2COC2H5)] (L=PPh3) (D) have been synthesized by the insertion of CS2 in L2CuCl2, L3IrCl3 and L2PdCl2, respectively in mixed solvent of dichloromethane and ethanol at room temperature. The complexes have been characterized by FTIR, UV-visible and ESR spectroscopy. All the complexes have been found to be air-stable. Complexes (A), (B) and (D) are distorted square planar while complex (C) is of distorted octahedral geometry.
通过在 L2CuCl2 中插入 CS2,在室温二氯甲烷和乙醇混合溶剂中分别合成了四种新的配合物 [L2Cu(S2COC2H5)] L=PPh3 (A), C3H4N2 (B)}, [L2IrCl2(S2COC2H5)] (L=PPh3) (C) 和 [L2Pd(S2COC2H5)] (L=PPh3) (D)、L3IrCl3 和 L2PdCl2 中插入 CS2 而合成的。这些配合物通过傅立叶变换红外光谱、紫外可见光谱和 ESR 光谱进行了表征。所有络合物均在空气中稳定存在。络合物 (A)、(B) 和 (D) 是扭曲的方形平面,而络合物 (C) 则是扭曲的八面体几何形状。
