The dinitrogen-tetrafluoroborato complex (Ph3P)2(Cl)(N2)(H)IrFBF3 reacts with 9-methylguanine in CH2Cl2 to give (+)BF4(-) (2).From a solution of 2 in methanol the complex (Ph3P)2(Cl)2(H)Ir(9-methylguanine) (3) is obtained.The reaction of with 9-methylguanine affords the complexes (+)C4F9SO3(-) (5) and (+)C4F9SO3(-) (6).The coordination of the guanine derivative to the iridium atom in 2, 5, 6 is discussed on the basis of the infrared spectra.The crystal structure of 3 was determined. 9-Methylguanine is coordinated via N(7).Intermolecular hydrogen bonding between the chloro-ligand and HN(1) of guanine leads to linear chains in the crystal. - Key words: Iridium(III) Complexes, Hydride, Dinitrogen, Tetrafluoroborate, Sulfonate, 9-Methylguanine as Ligands
