| Abstract: | The ready substitution of coordinated trifluoromethanesulfonate on pentaamminechromium(III) has been applied to the facile synthesis of a range of complexes of neutral ligands, Cr(NH3)5(L)]3+ (L = OH2, OHCH3, OS(CH3)2, OP(OCH3)3, OC(NH2)2, OC(NHCH3)2, OC(CH3) · N(CH3)2, OCH · NH2, OCH · N(CH3)2, NCCH3, NH3 and imidazole). The complexes have been characterized by microanalysis, electronic and infrared spectroscopy, and the lability of the neutral ligand towards acid hydrolysis determined, and compared with cobalt(III) analogues. |
