A series of nine novel diorganotin(IV) complexes of O,N,O' chelating ligands were synthesized viz., [n-Bu2Sn(L2)]2·0.25 (C6H14) (1), [Me2Sn(L1)]2·(C7H8) (2), [n-Bu2Sn(L1)]2·(C7H8) (3), [Me2Sn(L3)]2·(C7H8) (4), 2 [n-Bu2Sn(L3)]2·4 (n-Bu2Sn(L3)) (5), [Ph2Sn(L3)] (6), [Ph2Sn(L1)] (7), [Ph2Sn(L4)] (8) and [Ph2Sn(L2)] (9) and structurally characterized. The ligand scaffolds differ with respect to the chemical
合成了O,N,O ′螯合配体的一系列九种新颖的二有机锡(IV)配合物。,[ n -Bu 2 Sn(L 2)] 2 ·0.25(C 6 H 14)(1),[Me 2 Sn(L 1)] 2 ·(C 7 H 8)(2),[ n -Bu 2 Sn(L 1)] 2 ·(C 7 H 8)(3),[Me 2 Sn(L 3)] 2·(C 7 H 8)(4),2 [ n -Bu 2 Sn(L 3)] 2 ·4(n -Bu 2 Sn(L 3))(5),[Ph 2 Sn(L 3)] (6),[Ph 2 Sn(L 1)](7),[Ph 2 Sn(L 4)](8)和[Ph 2 Sn(L 2)](9)和结构特征。配体支架在配位的N和O原子之间的化学连接方面不同,该N或O原子是烷基或芳基部分。衍射结果表明,最小的甲基基团有利于通过Sn-O-Sn桥接和阳离子的六配位进行二聚。在这些双核衍生物中,亲核性较弱的酚盐O发现更多
