Abstract
Octamethylcyclotetraphosphonitrile and decamethylcyclopentaphosphonitrile react with the hexacarbonyls of molybdenum and tungsten to give tricarbonyls L,M(CO)3, co-ordination of the ligand occurring most probably through its nitrogen atoms. The octadimethylamido-derivative N4P4(NMe2)8 forms a tetracarbonyl L,W(CO)4. The quaternary iodide N4P4Me9I reacts with M(CO)6(M = Cr or Mo) to give the salts [N4P4Me9]+[M(CO)5l]+, in which 1H n.m.r. and i.r. spectra indicate donor–acceptor interaction between the ions.Keywords
