exchange of phenyl groups in solution and redox processes, respectively. In addition to single crystal X-ray structure analyses, NMR spectra involving the nuclei 1H, 31P, 77Se, 117/119Sn and 107/109Ag allowed a structural analysis of these complexes in solution. Each element present in complexes 5–8 consists of at least one isotope with nuclear spin I=1/2. In co-thermolysis experiments of these complexes
以膦配位的醋酸银和醋酸二有机锡与双(三甲基甲硅烷基)硫族化物反应合成了一系列异核银锡硫族化物配合物。除了具有通式[( i Pr 3 PAg) 2 (SnR 2 )E 2 ] 2 ( 1 – 6 , R=Me, Ph, t Bu and E=S, Se)的银配合物,[( i Pr 3 PAg) 3 (SnPh 2 )(SnPh)S 4 ] ( 7 ) 和 [( i Pr 3 PAg)(SnPh 2 )(SnPh)Se2 ] 2 ( 8 ) 分别通过溶液和氧化还原过程中的苯基交换得到。除了单晶 X 射线结构分析外,涉及核1 H、31 P、77 Se、 117/ 119 Sn 和107/109 Ag 的 NMR 光谱允许对溶液中的这些配合物进行结构分析。配合物5 – 8中存在的每种元素都由至少一种核自旋 I=1/2 的同位素组成。在这些配合物与 Zn(SC 2 H 4 S) 或 Zn(SeC 2
