Summary
Compounds of the types [RhL6](BF4)3, [RhL5X](BF4)2 (L=1-methylimidazole), [RhL4X2]X (L=1-methylimidazole, 1-nbutylimidazole, 1-vinylimidazole, 1-vinyl-2-methylimidazole, 2-methylimidazole, 2-ethylimidazole, 2-isopropylimidazole, 2-ethyl-4(5)-methylimidazole; X=Cl or Br) and [RhL4X2]BF4 (L = 1-n-butylimidazole, 1-vinylimidazole, 1-vinyl-2-methylimidazole, 2-ethylimidazole, 2-isopropylimidazole and 1,2-dimethylimidazole) have been prepared and characterized by conductivity measurements, i.r. and1H n.m.r. spectral studies. Analytical data agree with the monodentate nature of the ligands while a strongv(Rh-X) frequency reveals that the halogens aretrans to each other. The compounds also reveal d-d transition bands atca. 24000–22000 cm−1 in the visible region.
