ABSTRACT
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-(cyclo-hexa-none)oxalydihydrazone ligand. The charge-balance is supplied by two nitrate anions. The symmetry-unique Ag(I) ion is in a distorted tetra-hedral geometry coordinated by a P atom from a tri-phenyl-phosphane ligand, an O atom from a water mol-ecule and a bis-(cyclo-hexa-none)oxalydihydrazone ligand bidentate chelating through the O atom and one of N atoms. In the crystal, O-Hâ¯O and N-Hâ¯O hydrogen bonds link the components, forming chains along the b-axis direction. These chains are connected through weak C-Hâ¯O hydrogen bonds, leading to the formation of a two-dimensional supra-molecular network parallel to (001).
