Abstract
A series of neutral and anionic Rh(III)-chloride compounds bearing ammonia or imidazole (Im) ligands, and isostructural to Ru(III) complexes endowed with antineoplastic activity, were synthesized and characterized spectroscopically. The X-ray crystal structure of [ImH][ trans -RhCl 4 (Im) 2 ] was determined. Crystal data: monoclinic, space group C 2/ c , Z =4, a =13.133(3), b =7.977(1), c =16.683(4) A, β =113.84(2)°. The solution behaviour and some biological parameters of the new rhodium compounds, including cytotoxicity, in vitro interactions with DNA and in vivo antitumour activity against a tumour model, were investigated and compared with those of the corresponding ruthenium analogues.
