Abstract
Catena-(P4Se4)x was prepared in crystalline form from the elements usi ng iodine as a catalyst, and characterized by means of X-ray diffracti on and IR spectroscopy. Single-crystal investigations (space group P2( 1)/c, a = 1119.2(3), b = 728.2(2), c = 1142.5(2) pm, beta = 115.91(2)- degrees, V = 837.5(7).10(6) pm3) revealed parallel chains of P4Se3 het ero-norbornane units linked via Se atoms. Thus, being the first phosph orus selenide which does not contain discrete molecules, catena-(P4Se4 )x can be regarded as a polymeric form of alpha-P4Se4 or as a crystall ine modification of vitrous phosphorus selenide.
