7,11-(Butane-1,4-Diyldioxydi-o-Phenylenedimethylene)-6,6-Dichloro-4,4-Bis(pyrrolidin-1-yl)-2 λ(5),4 λ(5),6 λ(5)-Triphosphaza-1,3,5,7,11-Pentaazaspiro[5.5] Undeca-1,3,5-Triene

Abstract

The title compound, C<inf>29</inf>H<inf>42</inf>Cl<inf>2</inf>N <inf>7</inf>O<inf>2</inf>P<inf>3</inf>, is a phosphazene derivative with a bulky substituent attached through a spiro junction with two pyrrolidine rings. The six-membered C<inf>3</inf>N<inf>2</inf>P ring has a chair conformation, while the phosphazene ring has a slight envelope conformation. The two N atoms in the C<inf>3</inf>N<inf>2</inf>P ring are likely to be stereogenic. © 2005 International Union of Crystallography Printed in Great Britain - all rights reserved.
