The preparation and characterisation of square planar cationic rhodium(I) dicarbonyl complexes {[Rh((mim)2C=O)(CO)2]+BPh4 -] (1),{[Rh((mim)2CH2)(CO)2]+BPh 4-} (2) and{[Rh((mBnzim)2CH2)(CO)2]+BPh 4-} (3) [mim=N-methylimidazol-2-yl, mBnzim=N-methylbenzimidazol-2-yl] is reported. The carbonyl ligands in 2 and 3 are readily exchanged for triphenylphosphine to form{[Rh((mim)2CH2)(PPh3)2] +BPh4-} (7) and {[Rh((mBnzim)2CH2)(PPh3)2] +BPh4-} (8). Complexes 2 and 3 were characterised by multinuclear NMR spectroscopy as well as by X-ray crystallography. Structural characterisation by X-ray analysis confirmed that complexes 2 and 3 are essentially square planar.
