چکیده
The title compound, cis-[Re(C(12)H(24)O(4)P)Cl(2)O(C(18)H(15)P)], was prepared from the analogous trans isomer [Głowiak et al. (2000 ▶). Polyhedron, 19, 2667-2672] by a trans-cis isomerization reaction. The Re(V) atom adopts a distorted octa-hedral coordination geometry. Besides being coordinated by the oxide and the butano-late O atoms, the Re(V) atom is coordinated by a pair of chloride ligands and two P atoms in cis positions with respect to each other. In the crystal, adjacent mol-ecules are linked by weak C-H⋯Cl inter-actions, forming a three-dimensional network.

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 mol-ecules of the rhodium complex, two half-oc...
