Tetra-phenyl piperazine-1,4-diyldiphos-pho-nate.

ABSTRACT: The mol-ecule of the title compound, C(28)H(28)N(2)O(6)P(2), is organized around an inversion center located at the centre of the piperazine ring. Both piperazine N atoms are substituted by P(O)(OC(6)H(5))(2) phospho-ester groups. The P atoms display a slightly distorted tetra-hedral environment; the N atoms show some deviation from planarity. The O atoms of the P=O groups are involved in inter-molecular C-H?O hydrogen bonds, building R(2) (2)(22) rings, in extended chains parallel to the a axis. C-H?? inter-actions involving the phenyl rings further stabilize the packing.
