The tetranuclear complex[Ag4((-Ph2PNHPPh2)2((-OPh2PNPPh2O)2](PF6)2·CH3COCH3 containing bis(diphenylphosphino)amine (Ph2PNHPPh2) and deprotonated bis- (diphenylphosphino)amine-dioxide (OPh2PNPPh2O) was isolated and characterized by X-ray crys- tallography. The deprotonated OPh2PNPPh2O acts as a tridentate ligand in a chelating and bridging mode. Two of the four Ag atoms are in a trigonal planar environment composed of PO2 chro- mophore, whereas the other two are coordinated with PN donors in a distorted linear arrangement. The title complex (C51H47Ag2F6N2O3P5) crystallizes in triclinic, space group P -1 with a = 12.9552 (2), b = 14.1691(3), c = 15.8110(3)(A), α = 68.7500(10),β = 86.8840(10), γ = 75.6170(10)°, V = 2618.16 (8) (A)3, Mr = 1220.50, Z = 2, Dc = 1.548 g/cm3, F(000) = 1228 and μ(MoKα) = 0.965 mm-1. The final refinements converged at R = 0.0679 and wR = 0.1528 for 7001 observed reflections (I > 2σ(I)).
