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 AgI 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—HO and N—HO hydrogen bonds link the components, forming chains along the b-axis direction. These chains are connected through weak C—HO hydrogen bonds, leading to the formation of a two-dimensional supramolecular network parallel to (001).

In the title complex, [Ag(NO3)(C2H3N3S)(C18H15P)2]·CH3OH, the AgI ion exhibits a distorted tetrahedral coordination geometry formed by two P atoms from two triphenylphosphine ligands, one S atom from a 1H-1,2,4-triazole-5(4H)-thione ligand and one O atom from a nitrate ion. In the crystal, complex and solvent molecules are linked by O—HO and N—HO hydrogen bonds forming a chain along the b-axis direction. The chains are linked by weak C—HO hydrogen bonds forming a two-dimensional supramolecular architecture parallel to (001). In addition, an intramolecular N—HO hydrogen bond is observed.
