Stable, six coordinated Bu(2)SnLA type complexes have been prepared [where LH = RCOC:C(OH)N(C(6) H(5))N:CCH(3); R = -4-F-C(6)H(4)-(L(1)H), R = -4-Cl-C(6)H(4)-(L(2)H), R= -4-Br-C(6)H(4)-(L(3)H), R=-CF(3)(L(4)H) and AH = C(O)C(6) H(4) C(O)NCHR'COOH; R'= -H(A(1)H), -CH(3)(A(2)H), -CH(CH(3))(2)(A(3)H)] by the interaction of 1:1:1 molar ratios of di-n-butyltin(IV) dichloride with corresponding organic moieties in refluxing benzene using two moles of Et(3)N as a base. In these complexes LH and AH behave as bidentate and coordination is taking place through oxygen, this is inferred from IR and (13)C NMR studies. These complexes possess tin atoms in skew trapezoidal bipyramidal geometry with the C-Sn-C angles ranging from 149.88( degrees ) to 156.84( degrees ). Some of these complexes with their corresponding organic moieties (LH, AH) were tested for their antimicrobial activities.

已制备稳定的六种协调的 Bu(2)SnLA 型复合物 [其中 LH = RCOC:C(OH)N(C(6) H(5))N:CCH(3); R = -4-FC(6)H(4)-(L(1)H), R = -4-Cl-C(6)H(4)-(L(2)H), R= -4 -Br-C(6)H(4)-(L(3)H), R=-CF(3)(L(4)H) 和 AH = C(O)C(6) H(4) C (O)NCHR'COOH; R'= -H(A(1)H), -CH(3)(A(2)H), -CH(CH(3))(2)(A(3)H)] 通过 1 的相互作用使用两摩尔 Et(3)N 作为碱，回流苯中二正丁基锡 (IV) 二氯化物与相应有机部分的摩尔比为 1:1。在这些配合物中，LH 和 AH 表现为双齿，并且通过氧发生配位，这是从 IR 和 (13)C NMR 研究推断出来的。这些配合物具有倾斜梯形双锥几何形状的锡原子，C-Sn-C 角范围从 149.88(度) 到 156.84(度)。这些复合物中的一些与它们相应的有机部分 (LH,
