Abstract
Abstract The crystal structure of 1-phenyl-3-trifluoromethyl-1,3-propanedionatobis(triphenylphosphite)rhodium(I), [Rh(TFBA)(P(OPh) 3 ) 2 ] has been determined by means of single crystal X-ray diffraction. The structure was refined to a R value of 0.043.2719 Independant observed reflections were used. The unit cell is orthorombic, with space group Pca 2 1 , a = 20.761 A, b = 10.790 A, c = 19.035 A and Z = 4. The compound was prepared by substitution of the two carbonyl groups in the Rh(I) complex, 1-phenyl-3-trifluoromethyl-1,3-propanedionatobiscarbonylrhodium(I), [Rh(TFBA)CO) 2 ], by triphenylphosphite in methanolic medium. The significant difference between the two Rh-P bond lengths reveals that the oxygen atom nearest to the phenyl group has a larger trans influence than the other oxygen atom.
