Interactions of tetrakis(-µ-carboxylato)dirhodium(II), an antitumour agent, with nucleic acid bases. X-Ray crystal structures of [Rh2(acetato)4(theophylline)2] and [Rh2(acetato)4(caffeine)2]
Abstract
X-Ray crystal structure analyses of tetrakis(-µ-acetato)dirhodium(II) complexes of theophylline and caffeine have shown that in both complexes the dirhodium–tetra-acetate nucleus is occupied at the two axial positions by N(9) of the theophylline and caffeine bases.
