Abstract
Abstract The reaction of chromocene with trifluoroacetic acid in benzene yields blue-green crystals of the paramagnetic ionic complex [Cp2Cr]+[CpCr(OOCCF3)3]- (I) (μeff. 3.70 (297 K) to 3.41 (77 K) BM). Upon recrystallizing from THF, complex I gives blue needles of the monomer CpCr(OOCCF3)2 - THF (III) (μeff. 3.70 BM) which under treatment with an equimolar quantity of pyridine is transformed to violet needles of CpCr(OOCCF3)2 - Py (IV) (μeff. 3.44 BM). On the other hand, the successive action of excess trifluoroacetic acid and pyridine on complex III affords violet crystals of the octahedral monomer (C5H5N)3Cr(OOCCF3)3 (V) (μeff. 3.96 BM) which has been characterized by a complete X-ray analysis (CrOOOCCF3 (mean) 1.95(1) A, CrN (mean) 2.10(1) A). Similarly, complex V can be obtained along with [CpCrS]4 from the binuclear complex (CpCrSCMe3)2S.
