(N-Benzoyl-N-phenylhydroxylaminato)carbonyl(triphenylarsine)rhodium(I)

The mol-ecule of the title compound, [Rh(C13H10NO2){As(C6H5)3}(CO)] or [Rh(BPHA)(AsPh3)(CO)] (BPHA is the N-benzoyl-N-phenyl-hydroxy-laminate anion), comprises a bidentate N-benzoyl-N-phenyl-hydroxy-laminate anion coordinating through the O atoms to the soft Lewis acid, rhodium(I), and two monodentate ligands, viz. tri-phenyl-arsine and carbonyl. The resulting CO2As coordination environment around the central RhI atom is distorted square planar.=.
