In the crystal of the title compound, [Cu(2)Cl(4)(C(50)H(32)N(9)O(8)P(3))(2)], the binuclear mol-ecule is located across an inversion center. Each Cu(2+) cation is coordinated by two pyridine N atoms from symmetry-related 4,4;6,6-bis-(biphenyl-2,2'-diyldi-oxy)-2,2-bis-{2-[5-(pyridin-4-yl)-1,3,4-oxadiazol-2-yl]phen-oxy}cyclo-triphosphazene (L) ligands, a pair of bridging Cl(-) anions and a terminal Cl(-) anion, forming a distorted CuCl(3)N(2) square-pyramidal geometry. Weak intra-molecular C-H⋯O and inter-molecular C-H⋯N inter-actions occur in the crystal.
