Abstract
The molecular and crystal structure of tetraphenylphosphonium antimony(III) bis-dmit (H-2-dmit = 4,5-dimercapto-1,3-dithiole-2-thione) has been determined by X-ray diffraction. The structure was solved by Patterson methods. The least-squares refinements lead to the conventional R factor of 0.039. A conformational characterization is reported for an almost undistorted pentagonal bipyramidal coordination about the Sb metal center, achieved through intraanionic and secondary interanionic bond interactions between antimony and thiocarbonyl sulfur atoms. The anions form a linear polymeric association elongated in the c direction.File in questo prodotto:
