In the crystal, N—H⋯Cl and N—H⋯S hydrogen bonds link complex molecules, forming layers parallel to (001). These layers are connected through π–π stacking interactions [centroid–centroid distance = 3.665 (2) Å], leading to the formation of a three-dimensional network.

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—H⋯O and N—H⋯O hydrogen bonds forming a chain along the b-axis direction. The chains are linked by weak C—H⋯O hydrogen bonds forming a two-dimensional supramolecular architecture parallel to (001). In addition, an intramolecular N—H⋯O hydrogen bond is observed.

(anti-Chlorido-thio-semicabazide-κS)bis-(tri-phenyl-phosphane-κP)copper(I) 0.48-hydrate.

In the mononuclear title complex, [CuCl(CH5N3S)(C18H15P)2]·0.48H2O, the CuI ion is in a slightly distorted tetrahedral coordination geometry formed by two P atoms from two triphenylphosphane ligands, one S atom from a thiosemicarbazide ligand and one chloride anion. An intramolecular N—H⋯N hydrogen bond [graph-set motif S(5)] stabilizes the thiosemicarbazide ligand in its anti conformation, and an intramolecular N—H⋯Cl hydrogen bond between the hydrazine N—H group and the chloride anion influences the arrangement and orientation of the ligands around the metal center. A weak intramolecular C—H⋯Cl hydrogen bond is also present. In the crystal, complex molecules are connected through N—H⋯Cl hydrogen bonds originating from the amide –NH2 group, and through O—H⋯S and O—H⋯Cl hydrogen bonds involving the solvent water molecule. Both the direct N—H⋯Cl hydrogen bonds as well as the bridging hydrogen bonds mediated by the water molecule connect the complex molecules into zigzag chains that propagate along [010]. The solvent water molecule is partially occupied, with a refined occupancy of 0.479 (7).

Bis[μ-bis-(diphenyl-phosphan-yl)methane-κ(2) P:P'](μ-1-ethyl-thio-urea-κ(2) S:S)bis-[iodidocopper(I)] acetonitrile sesquisolvate.

In the dinuclear title compound, [Cu2I2(C3H8N2S)(C25H22P2)2]·1.5CH3CN, each CuI atom exhibits a distorted tetrahedral coordination with two P atoms from two bis(diphenylphosphanyl)methane (dppm) ligands, one metal-bridging S atom from the 1-ethylthiourea (ettu) ligand and one iodide ion. The dppm ligand and the bridging S atom of the ettu ligand force the two copper atoms into close proximity, leading to the formation of a close intramolecular Cu⋯Cu contact [3.3747 (17) Å]. The conformation of the dimeric complex is such that the two dppm ligands are located on one side of the dinuclear metal complex, while the two iodine atoms are pointed towards the other side of the complex, a conformation that is stabilized by two intramolecular N—H⋯I hydrogen bonds between the ettu NH2 and NHEt moieties and the I atoms. Another pair of symmetry-equivalent N—H⋯I hydrogen bonds is established between neighboring molecules across an inversion center, linking molecules into dimers. The dimers are connected with each other and with the interstitial acetonitrile solvent molecules via a range of weaker C—H⋯I and C—H⋯S interactions and through weak C—H⋯π interactions, leading to the formation of a three-dimensional network. One of the acetonitrile solvent molecules is disordered in a 1:1 ratio across a crystallographic inversion center.

The AgI ion presents a distorted tetrahedral coordination geometry. In the crystal, weak C—H⋯N and C—H⋯S hydrogen bonds link the complex molecules into a two-dimensional network parallel to (010).
