title: [μ-N,N,N',N'-Tetra-kis(diphenyl-phosphino-meth-yl)benzene-1,4-diamine-κP,P':P'',P''']bis-[bis-(nitrato-κO)palladium(II)].
abstract: The asymmetric unit of the title complex, [Pd(2)(NO(3))(4)(C(58)H(52)N(2)P(4))], contains one half-mol-ecule, 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, inter-molecular C-H⋯O inter-actions link the mol-ecules into chains, and π-π contacts between the phenyl rings [centroid-centroid distance = 3.928 (3) Å] may further stabilize the structure.
