Di­aqua­{μ₂-N,N′-bis­[(cyclo­hexa­nyl­idene)amino]­oxamide}­bis­(tri­phenyl­phosphane)silver(I) dinitrate

The dinuclear title compound, [Ag₂(C₁₄H₂₂N₄O₂)(C₁₈H₁₅P)₂(H₂O)₂](NO₃)₂, lies across an inversion center and consists of two [Ag(H₂O)(PPh₃)] units bridged by a bis­(cyclo­hexa­none)oxalydihydrazone ligand. The charge-balance is supplied by two nitrate anions. The symmetry-unique Ag^I ion is in a distorted tetra­hedral geometry coordinated by a P atom from a tri­phenyl­phosphane ligand, an O atom from a water mol­ecule and a bis­(cyclo­hexa­none)oxalydihydrazone ligand bidentate chelating through the O atom and one of N atoms. In the crystal, O—H...O and N—H...O hydrogen bonds link the components, forming chains along the b-axis direction. These chains are connected through weak C—H...O hydrogen bonds, leading to the formation of a two-dimensional supra­molecular network parallel to (001).
