7‐phenantroline (4,7‐phen) led to the formation of polymeric complexes of [SnPh2Cl2(4,7‐phen)]n (5) and [SnPh2Cl2(biq)]n (6). The NMR spectra, however, reveal the ligand lability in solution and suggest a coordination number of 5. The X‐ray crystal structures of complexes [SnMe2Cl2(5,5′‐Me2bpy)] (1), [SnMe2(NCS)2(bu2bpy)] (2) and [SnMe2(NCS)2(bphen)] (4) have been determined which reveal that the geometry around
当与二齿取代的吡啶基配体反应时,二有机锡(IV)配合物SnR 2 X 2(R = Me,Ph; X = Cl,NCS)形成一系列通用配合物。二氯化二甲基锡与5,5'-二甲基-2,2'-联吡啶(5,5'-Me 2 bpy)的反应导致形成[SnMe 2 Cl 2(5,5'-Me 2 bpy)] (1)。此外,SnMe 2(NSC)2与4,4'-二叔丁基-2,2'-联吡啶(bu 2 bpy),1,10-菲咯啉(phen)和4,7-二苯基1,10-菲咯啉(bphen)提供六配位配合物[SnMe 2(NCS)2(bu 2 bpy)](2),[SnMe 2(NCS)2(phen)](3)和[SnMe 2(NCS)2(bphen)](4)。使用元素分析,IR,多核NMR(1 H,13 C,119 Sn)和DEPT-135 ° NMR光谱对得到的络合物进行了表征。另一方面,二氯化二苯基锡与2,2'-联喹啉(biq)和4
