✦ Synopsis

Three metal complexes of general composition

[ Rh( PPh3) (dmgH)*R] (dmgH -= monoanion of dimethylglyoxime, R-&H&H;, CH2=CH-and C,H,C=C-) have been investigated by the quasirelativistic INDO/l method. Geometric models of the complexes were taken from X-ray structure analysis. The bonding situation has been analyzed in terms of bondmultiplicity indices and bicentric increments to the total energy. A decreasing trunk influence of the organ0 group evidenced from the X-ray data was not confirmed by the corresponding stabilization of the Rh-P bond.
