Abstract
The asymmetric unit of the title complex, [Pd2(NO3)4(C58H52N2P4)], contains one half-molecule, in which the central benzene ring is located on a crystallographic centre of inversion. The Pd atom has a distorted square-planar coordination consisting of two P and two O atoms. In the crystal structure, intermolecular C—H...O interactions link the molecules into chains, and π–π contacts between the phenyl rings [centroid–centroid distance = 3.928 (3) Å] may further stabilize the structure.
