The use of trichloroiminophosphoranes Cl3P=NR to control the concurrent release of the templating cation [RNH3]+ and chloride ligand via in situ P-N and P-Cl bond cleavage produced two new copper(II) chloride oligomers. The nature of the organic substituent R was a factor in determining the chain lengths. For n-propyltrichloroiminophosphorane, the hexanuclear cluster [n-PrNH3]2[Cu6Cl 14] (1) was obtained, while p-tolyltrichloroiminophosphorane generated the tetranuclear copper chloride salt [4-CH3C 6H4NH3][2-Cl-4-CH3C 6H3NH3][Cu4Cl10] (2). In both structures a two-dimensional framework displaying a herringbone arrangement is created by Cu-Cl secondary bonding interactions. The direct addition of the [n-PrNH3]+ cation to a CuCl2·2H 2O solution under the same reaction conditions produced [n-PrNH 3]2[CuCl4].
