Reactions of aminated cyclotriand cyclotetra-phosphazenes, viz., N3P3L6 and N4P4L8 (L = -NC4H80 , -NC5H io, -HNC6Hn and -HNC8H ,7) with W(CO)6 have been studied. [(N3P3L6)W(CO)3] derivatives are obtained with N3P3L6 while N4P4L8 yield tetracarbonyl substituted derivatives, [(N4P4L8)W(CO)4]. Mixed ligand tungsten tricarbonyls of the type [Ci2HgN2)(N3P3L6 or N4P4Lg)W(CO)3] have also been synthesi...
