title: Octahedral complexes of anti-cancer Pt(IV)(cyclohexyldiamine) agents with 9-methylguanine.
abstract: The compounds [Pt(IV)(dach)(9-methylguanine)2X2]2+ (X = Cl, OH) have been prepared and structurally characterized. Their existence shows that it is possible to accommodate two purine bases (in a cis configuration) and four other ligands around a Pt(IV) atom. The geometries of these complexes have very different orientations of the guanine rings as compared to their corresponding Pt(II) counterparts.
