Abstract

cis-Bis(isopropyl isocyanide)dicyanoplatinum(II), Pt ^II(CN-i- C ₃H ₇) ₂(CN) ₂ has been synthesized,and its solid-state characteristics have been investigated. X-ray crystallographic data show that Pt ^II(CN-i-C ₃H ₇) ₂(CN) ₂forms an extended linear chain (ELC) material in the solid state that is yellow and luminescent. Exposure of crystalline films of Pt ^II(CN-i-C ₃H ₇) ₂(CN) ₂to benzene vapor leads to a solid-state luminescence color change from yellow to blue and a loss of crystallinity. Single-crystal X-ray data obtained for a benzene solvate of Pt ^II(CN-i-C ₃H ₇) ₂(CN) ₂ suggest that the luminescent blue form observed in the thin film results from a structural rearrangement. In the benzene solvate single crystal the lattice is changed from a staggered to an eclipsed ELC material in which the unit cell has expanded by 20% in volume and contains one benzene molecule for every two PtII(Pt ^II(CN-i-C ₃H ₇) ₂(CN) ₂ molecules. The selectivity, kinetics, and reversibility of this transformation have been studied to determine if crystalline films of Pt ^II(CN-i-C ₃H ₇) ₂(CN) ₂would make a useful benzene sensor.
