Bis[μ-methyl-enebis(diphenyl-phosphine)]bis-[(5-nitro-1,10-phenanthroline)silver(I)] bis-(hexa-fluoridoanti-monate)

In the title compound, [Ag(2)(C(12)H(7)N(3)O(2))(2)(C(25)H(22)P(2))(2)](SbF(6))(2), the two Ag(I) atoms are bridged by the two methyl-enebis(diphenyl-phosphine) ligands and an eight-membered centrosymmetric metallacyclic ring is formed. The metal atom exhibits a distorted tetra-hedral coordination geometry, coordinated by two P atoms of the bridging ligands and two N atoms of the chelating 5-nitro-1,10-phenanthroline ligand. The latter ligand shows minor disorder, adopting two orientations with site occupancy factors of 0.84 and 0.16.
