Abstract

The crystal structures of three compounds formed from the crystallisation of different copper(II) salts (nitrate, acetate and sulphate) with the new ligand 1,3-bis[2-(4-pyridyl)ethyl]-benzene, C20H20N2 (L) are reported. The anion is incorporated into each structure, but it plays a completely different role in each case: [Cu2L4(NO3)(H2O)2]·3(NO3) (1) contains discrete ‘paddlewheel’ bimetallic clusters incorporating a nitrate ion at their centres. [Cu2L(Ac)3(OH)]n (2) contains unusual tetra-metallic clusters in which the acetate ions display three different coordination modes: the L ligands link the clusters into (100) sheets. [CuL2(SO4)]n·2n(H2O) (3) contains looped [0 1 0] chains in which both the L ligands and sulphate ions bridge adjacent metal ions.
