Syntheses and structures of adducts of stoichiometry MX:dpex (2:1)(n), M = CuI, AgI, X = (pseudo-) halogen, dppx = Ph2E(CH2)xEPh2, E = P, As

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)xEPh2, 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 (1H, 13C, 31P NMR, ESI MS) and in the solid state (IR).

AgCl,Br:dppm (2:1)2 adopt the familiar tetranuclear ‘step’ structure, AgNCO:dpem (2:1)2 (E = P, As) also derivative of that, as also is AgNO3:dppp (2:1)2. CuCN:dppm (2:1) is a 2-D polymer.Figure optionsDownload as PowerPoint slide
