Reaction of 1,10-phenanthroline with some five-valent phosphorus, arsenic, and antimony halides

Abstract

The compounds PCl₅,phen; 2SbCl₅,phen; AsCl₅,SbCl₅,phen; and AsCl₅,SbCl₅,AsCl₃ have been prepared and characterised (phen = 1,10-phenanthroline). I.r. and Raman spectra of the solid adducts and molecular-weight and conductivity measurements in nitrobenzene have been obtained and used to suggest structures based on six-co-ordinate species. Cell dimensions and space group are reported for AsCl₅,SbCl₅,AsCl₃. The PF₅–phen system yielded no adduct formation.
