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.
在标题化合物C60H54N3O18P3中，中心磷腈环基本呈平面状，六个拟合原子的均方根偏差为0.068 Å。P-N键长在1.575(2)-1.585(2) Å的狭窄范围内，表明电子在环内离域。每个P原子上的两个乙烯基苯甲酸酯取代基相对于中心P3N3环的平面上下排列。两个末端丙烯基的原子在两组位置上无序，精制的位点占有率比为0.249(12):0.751(12)和0.476(9):0.524(9)。未观察到分子间相互作用。
