title: Crystal structure of hexa-prop-2-en-1-yl 4,4',4'',4''',4'''',4'''''-[1,3,5,2λ(5),4λ(5),6λ(5)-tri-aza-triphosphinine-2,2,4,4,6,6-hexa-yl-hexa-kis-(-oxy)]hexa-benzoate.
abstract: In the title compound, C60H54N3O18P3, the central phosphazene ring is essentially planar, with an r.m.s. deviation of the six fitted atoms of 0.068 Å. The P-N bond lengths are within the narrow range 1.575 (2)-1.585 (2) Å, indicating the electrons are delocalized within the ring. The two ethenyl benzoate substituents on each P atom are located up and down with respect to the plane of the central P3N3 ring. The atoms of two terminal propenyl groups are disordered over two sets of sites, with refined site-occupancy ratios of 0.249 (12):0.751 (12) and 0.476 (9):0.524 (9). No intermolecular interactions are observed.
