| Metal Complexes of Heteroarenes, X [1]. 7 7 1 -Coordination of Phosphinine: Synthesis and Structure of cis-Dichloro-bis(2,6-dimethyl-4-phenyI-phosphinine)platinum  | | | | Abstract
| C/5-Dichloro-bis(2 ,6 -dimethyl-4 -phenyl-77'-phosphinine)platinum (3) has been prepared by ligand substitution from cis -dichloro(2,5-cyclooctadiene)platinum and characterized by spec troscopy ('H , 13C, 31P NMR, IR, UV-Vis), CV and X-ray diffraction (space group P2|/c, a = 14.998, b = 16.540, c -11.506 Ä, a = 7 = 90°, ß = 92.46°, Z = 4). In line with findings for simi lar P hybridization states, the Pt-P bond length (221 pm) in 3 equals that in 771 -phosphaalkene Pt complexes and falls short of the respective parameters in Pt phosphane species. The stretching frequencies u^c\ and the bond length Pt-Cl indicate that phosphinines and phosphaalkenes, relative to phosphanes, adopt a lower position on the rram'-influence scale. This gradation is also suggested by the coupling constants 1 J (195Pt,31P). | | | |
