The structure of the title complex, [Ag(C 11 H 15 N 3 S) 2 ]PF 6 , has monoclinic ( P 2 1 / c ) symmetry, and the silver atom has a distorted square-planar geometry. The coordination complex crystallized from mixing silver hexafluoridophosphate with a concentrated tetrahydrofuran solution of N , N -diethylphenylazothioformamide [ATF; systematic name: 3,3-diethyl-1-(phenylimino)thiourea] under ambient conditions. The resultant coordination complex exhibits a 2:1 ligand-to-metal ratio, with the silver(I) atom having a fourfold AgN 2 S 2 coordination sphere, with a single PF 6 counter-ion. In the crystal, however, one sulfur atom from an ATF ligand of a neighboring complex coordinates to the silver atom, with a bond distance of 2.9884 (14) Å. This creates a polymeric zigzag chain propagating along the c -axis direction. The chains are linked by C—H...F hydrogen bonds, forming slabs parallel to the ac plane.
