为了深入了解化学均质但几何异构体不同的配体在构建配位聚合物中的性能,两种二甲苯官能化的N-供体,具体地,p-BIMB和o-BIMB,(BIMB =双-(咪唑-1-基甲基)苯)在溶剂热条件下用CuCN和KI平行处理,在层扩散中用CuCl 2和NaN 3平行处理,从而提供了四种新的配位聚合物,其尺寸从1D到3D。特别是,亚铜配合物[Cu 2(CN)2(p-BIMB)]n(1)是一种三维结构,具有前所未有的双峰(8 × 102)(85.10)2拓扑结构和[Cu 2(CN)2(o-BIMB)]n(2)作为基于(CuCN)n网络和二价铜{[Cu(N3)2(p-BIMB)2](H2O)2}n(3)的波状片以[Cu(N3)2(o-BIMB)2]n(4)为金属稠环链状结构,通过倾斜互穿(4,4)网络组装成三维多链状结构。1 - 4的组装揭示了两个同分异构配体衍生的聚合物在性质上相似的规律。
To have an insight into the performance of chemically homogeneous but geometrically different isomeric ligands in constructing coordination polymers, two xylene-functionalized N-donors, specifically, p-BIMB and o-BIMB (BIMB = bis-(imidazol-1-ylmethyl)benzene), were treated, in parallel, with CuCN and KI under solvothermal conditions and with CuCl2 and NaN3 in layer diffusion, thereby affording four new coordination polymers with dimensions from 1D to 3D. In particular, the cuprous [Cu2(CN)2(p-BIMB)]n (1) is structured as a 3D framework showing an unprecedented bimodal (8 × 102)(85.10)2 topology and [Cu2(CN)2(o-BIMB)]n (2) as an undulated sheet based on a (CuCN)n network and the cupric {[Cu(N3)2(p-BIMB)2](H2O)2}n (3) is assembled as a 3D polycatenated framework based on the inclined interpenetrating (4,4) nets and [Cu(N3)2(o-BIMB)2]n (4) as a metal-fused ring catenation. The assemblies of 1−4 are of note for revealing a law that the polymers, comparably derived from two isomeric ligands, are similar in met...
