Chlorido{4-ethyl-1-[1-(pyrazin-2-yl)ethyl-idene]thio-semicabazidato-κS}bis-(triphenyl-phosphane-κP)silver(I).

The title compound, [Ag(C9H13N5S)Cl(C18H15P)2], crystallizes with four independent mol-ecules in the asymmetric unit, in each of which the Ag atom is in a distorted tetra-hedral coordination, defined by the chloride ligand, the S atom of the neutral ligand and two P atoms derived from the triphenyl phosphine ligands. The thio-semicarbazone acts as a monodentate ligand through its thione S atom. An intra-molecular N-H⋯Cl hydrogen bond occurs in two of the independent mol-ecules. In the crystal, the mol-ecules are assembled through N-H⋯Cl hydrogen bonds, forming chains along [101].
