Abstract

Red crystals of iodotriphenylphosphonium pentaiodide, C18H 15IP+·I5-, appear on cooling the black melt formed by heating a mixture of the commonplace reagents triphenyl-phosphine and molecular iodine. The compound has the highest I:P ratio hitherto established for a crystalline iodophosphonium polyiodide and constitutes the third member of the series Ph3P(I2) n (n = 1, 2 and 3). All atoms occupy general positions in the triclinic space group P1̄. Comparison of the bond lengths within the above series reveals a pattern of primary and secondary bonding that is highly reminiscent of the much studied polyiodides, I2n+1-, where one of the I2 moieties has been replaced by a P-I group. © 2006 International Union of Crystallography.
