Bis[(1S*,2S*)-trans-1,2-bis(diphenylphosphinoxy)cyclohexane]chloridoruthenium(II) trifluoromethanesulfonate dichloromethane disolvate

Abstract

The crystal structure of a racemic mixture of the title ruthenium(II) complex, [RuCl(C30H30O2P2)2]CF3SO3·2CH2Cl2, reveals that the coordination geometry about the coordinatively unsaturated metal centre is approximately trigonal-pyramidal, with the chlorine atom occupying one of the equatorial positions. The axial Ru—P bonds are longer than the equatorial Ru—P bonds and there is an acute P—Ru—P angle.
