In the mononuclear title complex, [Ag(C5H12N2S)(C18H15P)3](CH3COO)·CH3OH, the AgI ion is in a distorted tetrahedral coordination geometry formed by three P atoms from three triphenylphosphane ligands and one S atom from an N,N′-diethylthiourea ligand. In the crystal, the acetate anion is connected to the complex molecule via a pair of N—H⋯O hydrogen bonds [graph-set motif R

2(8)] and the solvent methanol molecule is connected to the anion via an O—H⋯O hydrogen bond. This aggregate is further connected through a weak C—H⋯O hydrogen bond, forming a chain along [100]. In addition, sixfold phenyl embraces with intermolecular distances of 6.6463 (13)–6.667 (2) Å are arranged in a chain along [001]. The combination of hydrogen bonding and phenyl⋯phenyl interactions leads to the formation of a two-dimensional network parallel to (010).
In the mononuclear title salt, [Ag(C3H8N2S)(C18H15P)3](CH3COO), the AgI ion exhibits a distorted tetrahedral coordination sphere defined by three P atoms from three triphenylphosphane ligands and one S atom from a 1,3-dimethylthiourea ligand. In the crystal, the acetate anion is linked with the complex cation via duplex N—H⋯O hydrogen bonds [graph-set motif R

In the mononuclear title complex, [CuI(CH3CN)(C18H15P)2], the CuI ion is in a distorted tetrahedral geometry, coordinated by two P atoms of two triphenylphosphane ligands, one N atom of an acetonitrile ligand and one iodide anion. The acetonitrile ligand is disordered over two sets of sites in a 0.629 (15): 0.371 (15) ratio. In the crystal, weak C—H⋯I hydrogen bonds link the molecules, forming a chain along [100].
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
