One carbonyl group in yl(1,3-diphenyl-1,3-propanedionato-O,O')rhodium(
I) was substituted by triphenylphosphine to yield the title compound,
[Rh(C15H11O2)(C18H15P)(CO)(3), which has a square-planar geometry abou
t the Rh atom. There are two crystallographically independent molecule
s in the asymmetric unit.
