Crystal Structure of [1-Phenyl-3-(4-nitrophenyl)triazenido 1-oxide-κ²N³,O]-bis(triphenylphosfine)silver(I), [Ag(O₂-NC₆H₄NNNOC₆H₅)(C₁₈H₁₅P)₂]

Abstract

The reaction between [Ag(PPh₃)₃(NO₃)] and 1-phenyl-3-(4-nitrophenyl) triazene 1-oxide desprotonated with potassium hydroxide in methanol yields crystalline [Ag(O₂NC₆H₄NNNOC₆H₅)(C₁₈H₁₅P)₂], the first mononuclear triazenido 1-oxide complex of Ag(I) including a [Ag(PPh₃)₂]⁺ fragment. In the asymmetric title complex, the coordination geometry about the Ag⁺ ion is tetrahedral, with one triazenido 1-oxide anion acting as a bidentate ligand (four-electron donor). The crystal belongs to the monoclinic system, space group P2₁/c with the cell dimensions a = 19.551(7), b = 19.342(9), c = 11.124(6)Å, β = 95.453(15)°, V = 4187(3)ų, Z = 4.
