Cyclic inorganic compounds. Part VIII. Aluminium tribromide addition compounds of hexabromo- and hexachloro-triphosphonitriles

Abstract

Addition compounds P₃N₃Br₆,AlBr₃, P₃N₃Br₆,2AlBr₃, and P₃N₃Cl₆, AlBr₃ result from reactions between aluminium tribromide and the appropriate phosphonitrile in carbon disulphide solution. I.r. spectra of the products can be assigned on the basis of the co-ordination of the aluminium tribromide to nitrogen atoms in the phosphonitrile ring.
