Phosphorus-nitrogen compounds- (Part 50): correlations between structural parameters for cylophosphazene derivatives containing ferrocenyl pendant arm(s)

The results of a systematic study of spiro-cyclotri/tetraphosphazenes with ferrocenyl pendant arm onthe basis of correlation between structural parameters were presented. The main parameters were obtained from Xray crystallography and ${}^{31}P$ NMR results in order to investigate the relationship between the δPspiro shift valuesand endocyclic and exocyclic NPN bond angles, and electron density transfer parameters. Structural parametersderived from 11 types of the ferrocenyl cyclophosphazene derivatives with 5- to 7-membered spiro-rings introducedto the literature from our research group were studied and compared with each other.
