Abstract

The dihydridocarbaferraborane [FeH₂(2,3-Me₂-2,3-C₂B₄H ₄)₂] reacts with [Co(PEt₃)₄], [Pt₂(μ-cod)(PEt₃)₄] (cod = cyclo-octa-1,5-diene), and [Fe(cod)(η-C₅H₅)] to afford, respectively, the dimetallic species [CoFe( Me₄C₄B₈H₈)(PEt₃) ₂], [FePt(Me₄C₄B₈H₈) (PEt₃)₂], and [Fe₂(Me₄C₄B₈H₈) (η-C₅H₅)], each of which features a metal-metal connectivity. An X-ray diffraction study of the iron-cobalt molecule shows that it belongs to the structural family involving two pentagonal bipyramids fused about a common iron apical vertex and sharing a double-capping BH function. Crystals are orthorhombic, space group P2₁2₁2₁ with a = 16.533(5), b = 11.012(2), c = 16.279(3) Å, and four molecules per unit cell. Using 3 496 amplitudes recorded on a four-circle diffractometer at 291 ± 1 K the structure has been refined to R 0.043. The Co-Fe distance is 2.5300(8) Å; 0.05 Å longer than that in [CoFe(Me₄C₄B₈H₈) (η-C₅H₅)].
