Dicarbonyl-{3,3′-di-tert-butyl-5,5′-di-methoxy-2, 2′-bis[(4,4,5,5-tetraphenyl-1,3,2-dioxaphospho-lan-2-yl)-oxy-κP] biphen-yl}hydridorhodium(I) diethyl ether monosolvate
In the title compound, [Rh(C 74H 68O 8P2)H(CO) 2]·C 4H 10O, the C 2HP 2 coordination set at the Rh I ion is arranged in a distorted trigonal-planar geometry with one P atom of the diphosphite mol-ecule and the H atom adopting the axial coordination sites.
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-κ2 P,P′}hydrido(triphenylphosphane-κP)rhodium(I) diethyl ether trisolvate
In the title compound, [RhH(C74H68O8P2)(C18H15P)(CO)]·3C4H10O, the CHP3 coordination set at the RhI 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].
{2-[Bis(2,4-di-tert-butylphenoxy)-phosphanyloxy-κP]-3, 5-di-tert-butylphenyl-κC 1}[(1,2,5,6-η)-cycloocta-1,5-diene] rhodium(I) toluene monosolvate
The reaction of (η 3-allyl)[(1,2,5,6-η)-cycloocta-1,5- diene]rhodium(I) with tris-(2,4-di-tert-butylphenyl)phosphite in toluene produces the title compound, [Rh(C 42H 62O 3P)(C 8H 12)]·C 7H 8, by spontaneous metallation at one of the nonsubstituted phenyl ortho-C atoms of the phosphite molecule. The coordination geometry at the Rh I ion is distorted squareplanar. The toluene solvent molecule is disordered over two different orientations, with site-occupation factors of 0.810 (2) and 0.190 (2).
