The single crystal X-ray structure determination of {[Cu(tpt)(o-phthalate)]·31/3(C2H2Cl4)}n (tpt=2,4,6-tri-4-pyridyl-1,3,5-triazine, C2H2Cl4=1,1,2,2-tetrachloroethane=TCE) shows a 3D network in which CuII centres are linked by 3-connecting tpt ligands with the topology of a 12,3 net. CuII centres are further linked by o-phthalate dianions. The copper coordination geometry is square pyramidal, with o-phthalate oxygen donors trans to each other in the basal plane and the remaining positions taken by the pyridines of three linking tpt units. The solvent accessible void space is ~65%. The pale blue-green crystalline desolvate, obtained by heating to 200°C or washing the TCE solvate with acetone ..
