The synthesis and crystal structure of bis-[3,3-diethyl-1-(phenyl-imino-?N)thio-urea-?S]silver hexa-fluorido-phosphate.

ABSTRACT: The structure of the title complex, [Ag(C₁₁H₁₅N₃S)₂]PF₆, has monoclinic (P2₁/c) symmetry, and the silver atom has a distorted square-planar geometry. The coordination complex crystallized from mixing silver hexa-fluorido-phosphate with a concentrated tetra-hydro-furan solution of N,N-di-ethyl-phenyl-azo-thio-formamide [ATF; systematic name: 3,3-diethyl-1-(phenyl-imino)-thio-urea] under ambient conditions. The resultant coordination complex exhibits a 2:1 ligand-to-metal ratio, with the silver(I) atom having a fourfold AgN₂S₂ coordination sphere, with a single PF₆ 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.
