Abstract
Copper(II) complexes incorporating the isomeric tolyl-derivatised terpyridine ligands, 4′-p-tolyl-2,2′:6′,2′′-terpyridine (L1) and 6′-p-tolyl-2,2′:2′′,4′-terpyridine (L2) have been prepared and characterised by X-ray diffraction. The first of these is a co-crystal of type [Cu(L1)(NO3)2]·[Cu(L1)(NO3)(EtOH)]NO3·MeOH while the second is a single complex of type [Cu(L2)2(NO3)]NO3·0.5MeOH·1.5H2O. Crystallisation of a mixture of both products from ethanol/methanol (1:1) yields an unusual co-crystalline product of stoichiometry [Cu(L2)2NO3]2[Cu(L1)(NO3)2](NO3)2 whose structure was also confirmed by an X-ray stucture determination. §Dedicated to Professor Peter Williams in honour of his contribution to chemistry over many years.
