Abstract

Single crystal X-ray studies have defined the structures of a number of adducts of the form MX:dpex (2: 1), M = univalent coinage metal (Cu, Ag), X = (pseudo-)halide, dpex = bis(diphenylpnicogeno)alkane, Ph2E(CH2)(x)EPh2, E = P, As, of diverse types, some novel. The adducts of AgCl,Br:dppm and AgNCO:dpem (x = 1) are tetranuclear as is the AgNO3:dppp (x = 3) array, all derivative of the familiar 'step' structure while the combination CuCN:dppm yields a two-dimensional web of twenty-membered macro/metallacycles. Synthetic procedures for all adducts have been reported. All compounds have been characterized both in solution (H-1, C-13, P-31 NMR, ESI MS) and in the solid state (IR). (c) 2005 Elsevier B.V.
