reaction of Zn(II) and Co(II) with thiosalicylic acid, o-HSC6H4COOH, and its methyl ester has led to the following complexes: [Zn(SC6H4COO)] (1), (NEt4)Na[Zn(SC6H4COO)2].H2O (2), (NEt4)2Na[Co(SC6H4COO)3].2H2O (3), (NEt4)3Na3[(Co(SC6H4COO)3)2].6MeOH (4), [Zn(SC6H4COOMe)2] (5), and [Co(SC6H4COOMe)n], n = 2 (6), 3 (7). These ligands have not allowed stabilization of Co(II) in a sulfur-oxygen coordination
Zn(II)和Co(II)与硫代水杨酸o-HSC6H4COOH及其甲酯的反应生成以下络合物:[Zn(SC6H4COO)](1),(NEt4)Na [Zn(SC6H4COO) 2] .H2O(2),(NEt4)2Na [Co(SC(6H4COO)3] .2H2O(3),(NEt4)3Na3 [(Co(SC6H4COO)3)2] .6MeOH(4),[Zn(SC6H4COOMe) 2](5)和[Co(SC6H4COOMe)n],n = 2(6),3(7)。这些配体不允许在硫-氧配位环境中稳定Co(II)。配合物2-4和7的结构已经通过晶体学确定。2-4的那些显示出显着的相似性,例如-SC6H4COO-阴离子作为螯合配体的行为以及钠离子作为结构元素的参与。因此,配合物2中[Na(Zn(SC6H4COO)2)(H2O)]-阴离子的结构可描述为通过[Na(H2O)]连接的连续[Zn(SC6H4COO)2]
