The complex [Cr(tpy)(O3SCF3)3] (tpy = 2,2′:6′,2′′-terpyridine) is readily made from [Cr(tpy)Cl3] and is a convenient precursor to [Cr(tpy)2][PF6]3 and to [Cr(tpy)(4′-(4-tolyl)tpy)][PF6]3 and [Cr(tpy)(5,5′′-Me2tpy)][PF6]3 (4′-(4-tolyl)tpy = 4′-(4-tolyl)-2,2′:6′,2′′-terpyridine; 5,5′′-Me2tpy = 5,5′′-dimethyl-2,2′:6′,2′′-terpyridine); these are the first examples of heteroleptic bis(tpy) chromium(III) complexes
络合物[Cr(tpy)(O 3 SCF 3)3 ](tpy = 2,2':6',2''-叔吡啶)易于由[Cr(tpy)Cl 3 ]制成,是方便的前体[Cr(tpy)2 ] [PF 6 ] 3和[Cr(tpy)(4'-(4-甲苯基)tpy)] [PF 6 ] 3和[Cr(tpy)(5,5'-Me 2 tpy)] [PF 6 ] 3(4'-(4-甲苯基)tpy = 4'-(4-甲苯基)-2,2':6',2''-吡啶; 5,5''-Me 2 tpy = 5,5''-二甲基-2,2':6',2''-叔吡啶); 这些是杂合双(tpy)铬(III)配合物的第一个实例。2 [Cr(tpy)2] [PF 6 ] 3 }·5MeCN,[Cr(tpy)(4'-(4-tolyl)tpy)] [PF 6 ] 3 ·3MeCN和[Cr(tpy)(5,5'-Me 2 tpy )] [PF 6 ] 3 ·3MeCN已
