Carbon­yl{3,3′-di-tert-butyl-5,5′-dimeth­oxy-2,2′-bis­[(4,4,5,5-tetra­methyl-1,3,2-dioxaphospho­lan-2-yl)­oxy]biphenyl-κ²P,P′}hydrido(triphenyl­phosphane-κP)rhodium(I) diethyl ether tris­olvate

In the title compound, [RhH(C₇₄H₆₈O₈P₂)(C₁₈H₁₅P)(CO)]·3C₄H₁₀O, the CHP₃ coordination set at the Rh^I ion is arranged in a distorted trigonal–bipyramidal geometry with the P atoms adopting equatorial coordination sites and the C atom of the carbonyl ligand as well as the H atom adopting the axial sites. The asymmetric unit contains two very similar mol­ecules of the rhodium complex, two half-occupied diethyl ether mol­ecules and further diethyl ether solvent mol­ecules which could not be modelled successfully. Therefore contributions of the latter were removed from the diffraction data using the SQUEEZE procedure in PLATON [Spek (2009). Acta Cryst. D65, 148–155].
