FIRST STRUCTURAL CONFIRMATION OF DIFFERENT GEOMETRICAL ISOMERS IN THE SAME CRYSTAL LATTICE - THE CRYSTAL STRUCTURE OF BENZOYLACETONATOCARBONYLTRIPHENYLPHOSPHINERHODIUM(I)

摘要

The first structural confirmation of two different [Rh(BA)(CO)(PPh(3))] isomers (BA = benzoylacetonate, CH3(CO)CH(CO)C6H5), namely one with PPh(3) cis to the oxygen atom nearest to the phenyl group and the second isomer with PPh(3) trans to the oxygen nearest to the phenyl group, in the same crystal lattice is reported. The small influence of the different substituents is illustrated by the near equal Rh-O, Rh-P and Rh-C bond distances in the two different isomers. The structure crystallizes in the triclinic system, space group P
