在甲醇中，CuSO(4)和S、S的二苯基亚硫亚胺、Ph(2)SNH1的溶液与三偏苯基三甲酸钠(H(3)TMA)在甲醇中反应，形成了二维配位网络[Cu(3)(Ph(2)SNH)(6)(TMA)(2)]，其中每个三偏位酸与三个铜中心相连。向反应混合物中添加其他溶剂会引起网络形状的改变。用这种方法制备了三种晶型，并用X射线结晶学对其进行了表征。其中包括已知的蜂窝结构，2，砖墙结构，3，基序和人字形结构，4，这是含过渡金属的三元系化合物的新构型。观察到的超分子异构化的关键是1促进铜(II)中心的结构异构化的能力。与铜中心为正方形平面的2相反，4类似于同系物间的铜中心，同时具有平面和四面体的铜中心。还准备了一个相关的复合体，它由三个铜中心的离散单元组成。它们通过氢键进一步连接成一个2-D网络。
Reaction of a solution of CuSO(4) and S,S'-diphenylsulfimide, Ph(2)SNH 1, with sodium salts of trimesic acid (H(3)tma) in MeOH gives the 2-D coordination network [Cu(3)(Ph(2)SNH)(6)(tma)(2)] in which each trimesate is bound to three copper centres. Addition of other solvents to the reaction mixture causes a change in the shape of the network. By this route, three forms have been prepared and characterised by X-ray crystallography. These include the known honeycomb, 2, and brick-wall, 3, motifs and a herringbone, 4, arrangement which is novel for transition metal-containing trimesate complexes. Key to the supramolecular isomerism observed is the ability of 1 to facilitate structural isomerism at copper(II) centres. In contrast to 2 in which the copper centres are square planar, 4 is analogous to an inter-allogon, with both planar and tetrahedral copper centres. Also prepared is a related complex which is composed of discrete units of three copper centres. These are further linked into a 2-D network by hydrogen bonds.
