the hydrazone ligand 1-(3′-carboxyphenylhydrazono)naphthalene-2-one (H2L) was employed to generate three new organotin(IV) compounds with the general formula of [RxSnIV(HL)y] (where R = Me, x = y = 2 (1); R = n-Bu, x = 3, y = 1 (2), and R = Ph, x = 3, y = 1 (3)). The single-crystal structures of 1 and 3 were examined to establish the coordination environment about Sn(IV). Compound 1 possesses a hepta-coordinate

配体 1-(3'-carboxyphenylhydrazono)naphthalene-2-one (H 2 L) 生成三种新型
有机锡 (IV) 化合物,通式为 [R x Sn IV (HL) y ](其中 R = Me,x = y = 2(1);R = n- Bu,x = 3,y = 1(2),R = Ph,x = 3,y = 1(3))。检查了1和3的单晶结构以建立 Sn(IV) 的配位环境。化合物1具有Me 2 Sn IV O 5的发色配位环境的七配位均聚物。另一方面,化合物3具有带有 Ph 3 SnO 发色单元的单体扭曲四面体几何结构。1-3谱图中的119 Sn-NMR 信号分别位于 145.5、120.1 和 -104.4 ppm,表明它们是同构的,在溶液中采用四坐标四面体几何结构。三者中1和3的
生物活性截然不同。1的抗氧化活性在
