Phosphorus-nitrogen compounds (Part 51): the relationship betweenspectroscopic and crystallographic data of mono- and di-spirocyclophosphazenederivatives with 4-fluoro/nitrophenylmethyl pendant arm/arms
Abstract:A great wealth of structural information about phosphazenes can be gleaned from the combined spectroscopic and crystallographic data. When data from 31 P NMR spectroscopy and X-ray crystallography are put together like pieces in a puzzle, a number of correlations can be obtained for phosphazene derivatives. A systematic study concerning the correlations among the structural parameters (e.g., 31 P NMR data, endocyclic/exocyclic NPN bond angles and bond lengths) revealed some characteristics of mono-and di-spiro… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
