Abstract

The condensation of m-aminobenzoic acid with dichloroglyoxime has resulted in a new dioxime, di-m-aminobenzoyl glyoxime (DmabaH₄) (I). Based on the latter, coordination 2D polymers {[Zn(DmabaH₂)(H₂O)(dmf)] ⋅ dmf}_n (II), {[Cd(DmabaH₂)(H₂O)₂] ⋅ 0.5dmf ⋅ 4H₂O}_n (III), and {[Mn(DmabaH₂)(H₂O)(dmf)] ⋅ dmf}_n (IV) have been sythesized. The compositions and structures of new Zn(II), Cd(II), and Mn(II) compounds have been determined by various physicochemical methods, including X-ray diffraction (CIF files CCDC nos. 2 004 634 (II), 2 004 635 (III), and 2 004 636 (IV)). In compounds II–IV, DmabaH₄ acts as a bridging ligand, which is tetradentate coordinated as a dianion by three metal ions using a donor set of N₂O₂ atoms. This ligand is coordinated by one metal atom through two nitrogen atoms of the dioxime fragment in a bidentate chelate manner forming five-membered chelate rings, and by the other two monodentally using two oxygen atoms belonging to the carboxyl groups of two benzoic fragments. The coordination polyhedra of metal atoms in II–IV are completed to octahedrons by oxygen atoms of dmf and water molecules; the donor set of atoms is N₂O₄.

基于二氨基苯甲酰乙二肟的Zn（II），Cd（II）和Mn（II）二维配位聚合物的合成和结构研究

摘要

的缩合米氨基苯甲酸与dichloroglyoxime已导致新的二肟，二间氨基苯甲酰基乙二肟（DmabaH ₄）（我）。基于后者，配位二维聚合物{[Zn（DmabaH ₂）（H ₂ O）（dmf）]⋅dmf} _n（II），{[Cd（DmabaH ₂）（H ₂ O）₂ ]⋅0.5dmf⋅ 4H ₂ O} _n（III）和{[Mn（DmabaH ₂）（H ₂ O）（dmf）]⋅dmf} _n（IV）已合成。新的Zn（II），Cd（II）和Mn（II）化合物的组成和结构已通过多种物理化学方法测定，包括X射线衍射（CIF文件CCDC No.2,004634（II），20004 635（III）和2 004 636（IV））。在化合物II – IV中，DmabaH ₄起到桥联配体的作用，使用供体组N ₂ O ₂将三齿的四齿配位为二价阴离子。原子。该配体通过二齿肟螯合物的一个金属原子穿过二肟片段的两个氮原子配位，形成五元螯合环，而另外两个通过单齿使用两个氧原子，它们属于两个苯甲酸片段的羧基。II-IV中金属原子的配位多面体由dmf的氧原子和水分子完成为八面体。供体原子为N ₂ O ₄。
