摘要

Reaction of a solution of CuSO_4 and S,S'-diphenylsulfimide,PH_2SNH 1,with sodium salts of trimesic acid(H_3tma)in MeOH gives the 2-D coordination network[Cu_3(PH_2SNH)_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 5 which is composed of discrete units of three copper centres.These are further linked into a 2-D network by hydrogen bonds.
