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

The dinuclear title compound, [Ag 2 (C 14 H 22 N 4 O 2 )(C 18 H 15 P) 2 (H 2 O) 2 ](NO 3 ) 2 , lies across an inversion center and consists of two [Ag(H 2 O)(PPh 3 )] 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).
