Abstract

Abstract: A number of linear, short-chain phosphazenes have been prepared as structural models for three classes of phosphazene linear high polymers. X-ray diffraction results from studies of OP (CI,) NPCI,(7), OP (C1,) NP (C1,) NPC13 (lo),[CI, PNP-(Cl2) NP (CI2) NPC1,]+ PCI6-(14), OP (OPh), NP (OPh),(8), OP (NHPh), NP (NHPh),(9), and OP (NHPh) 2NP- (NHPh) 2NP (NHPh) 3 (12) suggest different values for the bond angles and bond lengths ...
