Reaction of silver(I) chloride with 1-(4-nitro­phen­yl)thio­urea and tri­phenyl­phosphane ligands of 1:2:1 ratio leads to the mononuclear complex [AgCl(C7H7N3O2S)(C18H15P)2]. In the crystal, bifurcated N—H⋯Cl and a weak C—H⋯O hydrogen bonds link mol­ecules into a two-dimensional network.

Two metal(I) complexes containing triphenylphosphine (PPh 3 ) and 1-(4-nitrophenyl)thiourea (NPTU) ligands were prepared, namely, [MBr(NPTU)(PPh 3 ) 2 ] (M = Cu (1) and Ag (2)). Both compounds (1) and (2) exhibit a distorted tetrahedral metal coordination environment with two P atoms from two PPh 3 ligands, one terminal S atom from the NPTU ligand and a bromide ion. An intramolecular N−H · · · Br hydrogen bond is observed (graph set motif S(6)). Amine and bromide units from neighbouring molecules are linked via bifurcated (N−H) 2 · · · Br hydrogen bonds forming 1D zigzag chains along [001] with an R 2 1 (6) graph set motif. Neighbouring chains are connected through C−H · · · O hydrogen bonds leading to the formation of a three-dimensional network.

In the mononuclear title complex, [Ag(SCN)(C18H15P)3], the AgIcenter is in a slightly distorted tetrahedral coordination geometry formed by one S atom from a terminal thiocyanate ligand and three P atoms from three triphenylphosphane ligands. In the crystal, weak C—H...N hydrogen bonds connect molecules into a two-dimensional network parallel to (10\overline{1}). One of the phenyl rings is disordered over two positions which were refined with an occupancy ratio of 0.715 (16):0.285 (16).
