Full TextAbstract
The molecule of the title compound, C28H28N2O6P2, is organized around an inversion center located at the centre of the piperazine ring. Both piperazine N atoms are substituted by P(O)(OC6H5)2 phosphoester groups. The P atoms display a slightly distorted tetrahedral environment; the N atoms show some deviation from planarity. The O atoms of the P O groups are involved in intermolecular C—H...O hydrogen bonds, building R2 2(22) rings, in extended chains parallel to the a axis. C—H...O interactions involving the phenyl rings further stabilize the packing.
