4′,4′,6′,6′-Tetrachloro-3-(4,6-dimethylpyridin-2-yl)-3,4-dihydrospiro[1,3,2-benzoxazaphosphinine-2,2′-(2λ5,4λ5,6λ5-cyclotriphosphazene)

Abstract

The title compound, C14H14Cl4N5OP3, is a phosphazene derivative with a bulky substituent attached through a spiro junction. The C3NPO ring at the spiro junction has a twist–boat conformation, while the phosphazene ring has a flattened-boat conformation. The Pspiro atom is likely to be stereogenic.
