(CuI)2P14: ein neues Phosphorpolymer in einer Kupferhalogenid-Matrix /(CuI)2P14: a Novel Phosphorus Polymer in a Copper Halide Matrix

Abstract

Abstract (CuI)2P14 is a new adduct of copper iodide to a neutral phosphorus polymer. It is obtained by reaction of Cul and Pred at 400 °C. The compound crystallizes monoclinically, space group P21/c (No. 14), a = 9.919(2), b = 9.718(2), c = 16.478(3) Å, β = 105.71(1)°, V = 1529.0(7) Å3, with Z = 4. The crystal structure was refined to R1 = 0.029 for 2680 reflections and 173 parameters. It contains a new polymeric phosphorus allotrope with the translational unit P14 ±0 consisting of experimentally unknown [P12] groups which are linked by [P2] fragments. The phosphorus rods consist of five-and six-membered rings, and are coordinated only by copper atoms.
