摘要：
The structure of [Rh(C4H7N2O2)(2)(C2H5)(C18H15P)] consists of discrete complex molecules in which the Rh atom displays distorted octahedral coordination; the two dimethylglyoxime ligands lie in the equatorial plane and the ethyl and triphenylphosphine groups occupy the axial positions. The Rh atom is displaced by 0.130 (1) Angstrom from the mean plane through the four oxime N donor atoms in the direction of the P atom. The Rh-N distances range from 1.903 (6) to 1.993 (6) Angstrom, while the axial Rh-P and Rh-C distances are 2.461 (2) and 2.064 (7) Angstrom, respectively. Comparison of the results with those obtained previously for analogous compounds containing the axial fragment Ph(3)P-Rh-X indicates that the trans influence of X is determined by its sigma-donor power.
