Abstract

The donor-acceptor complex [Cl-I-C≡C-Ph]- has been prepared as the methyl-triphenyl-phosphonium salt from 1-iodo-2-phenylacetylene and [PMePh3]N3 in CH2Cl2 solution. It forms co­lourless single crystals which were characterized by a crystal structure determination. Space group Pbca, Z = 8, lattice dimensions at -80 °C: a = 1047.1(1), b = 1700.3(1), c = 2793.2(1) pm, R = 0.035. The chloride ion is coordinated at the io­dine atom of the 1-iodo-2-phenylacetylene molecule in a nearly linear arrangement [CI-I-C≡C-Ph]- with bond lengths I-Cl of 302.4 pm and I-C of 203.1(5) pm.

Keywords: Chloride Complex of 1-Iodine-2-phenylacetylene; Crystal Strucure
