ABSTRACT:     Copper(I) and silver(I) chloride complexes containing triphenylphosphine (PPh3) and 4-phenyl- thiosemicarbazide (4-PTSC) ligands were prepared and structurally analyzed, namely [CuCl(4-PTSC)(PPh3)2] (1) and [AgCl(4-PTSC)(PPh3)2]CH3CN (2). Both compounds (1) and (2) exhibit a distorted tetrahedral metal coordination environment with two P atoms from two PPh3 ligands, one terminal S atom from the 4-PTSC ligand and a chloride ion. Intramolecular N−H · · · Cl and N−H · · · N hydrogen bonds are observed (graph set motifs S(6) and S(5), respectively). In the crystals of both complexes, molecules are linked to form dimers via bifurcated N−H · · · Cl hydrogen bonds involving the amine and chloride units. For compound (2), a solvate acetonitrile molecule acts as a hydrogen bond donor and acceptor via C−H(CH3CN) · · · Cl and C−H · · · N(CH3CN) interactions, leading to the formation of 1D chains along [010].
