The first examples of platinum(II)-amine complexes containing 1,2-dicarba-closo-dodecaborane(12)

Treatment of the labile precursor complexes cis- or trans-[PtCl(dmf)(NH3)2]OTf (dmf=N,N-dimethylformamide; OTf=trifluoromethanesulfonate) with the monodentate 1-aminoalkyl-1,2-carborane ligands NH2(CH2)nC2B10H11 (n=1,3) afforded the moderately-stable species cis- or trans-[PtCl(NH3)2{NH2(CH2)nC2B10H11}]OTf, respectively. The novel complexes are the first examples of platinum(II)-amine derivatives containing a 1,2-dicarba-closo-dodecaborane(12) (closo-1,2-carborane) ligand.
