Abstract

Two of the five possible geometrical isomers of [RhCl₂(edpp)₂]⁺ were formed by reaction of RhCl₃ · 2H₂0 with edpp (edpp=(2-aminoethyl)diphenylphosphine) in 1:2 molar ratio in ethanol. The chlorides of the isomers were separated by fractional crystallization from ethanol. The structures of the more soluble (main product) and the less soluble (minor product) complexes were determined by X-ray analyses to have the trans(Cl,Cl), cis(P,P) and cis(Cl,Cl), trans(P,P) configurations, respectively. Crystal data are: for trans(Cl,Cl), cis(P,P)-[RhCl₂(edpp)₂]Cl-2C₂H₅OH, triclinic, space group P1, with a= 10.024(3), b=18.865(3), c=9.833(2) Å, α=97.66(l), β=103.92(2), γ=82.30(2)°, and Z=2, and for cic(Cl,Cl), trans(P,P)-[RhCl₂(edpp)₂]Cl·4H₂O, triclinic, space group P1, with a= 11.341(4), b=17.780(6), c=8.712(3) Å, α=95.60(4), β=112.31(3), γ=82.56(4)°, and Z=2. The trans influence of the P atom on the Rh-N and Rh-P bond lengths is observed. The mean Rh-N and Rh-P bond lengths (2.125(4) and 2.300(1)Å) in the trans(Cl,Cl), cis(P,P) isomer are respectively longer and shorter than those of the cis(Cl,Cl), trans(P,P) isomer (2.078(12) and 2.336(3)Åt). ¹³C NMR and absorption spectra of the isomers were recorded and are discussed.
