Probing Structural Diversity in a Series of Perhydrocarbyl Heterobimetallic Complexes Associating Tantalum and 3d (Cr, Mn, Fe, Co, Ni) Transition Metals.

ABSTRACT: Salt metathesis between an alkali-stabilized tantalate complex, [Li(thf)₂][Ta(CtBu)(CH₂tBu)₃] (1), and a series of alkylcyclopentadienyl 3d transition metal halide dimers, [Cp'M(μ-X)]₂ (2-MX, Cp' = 1,2,4-tBu₃C₅H₂, X = Cl, Br or I), provides a set of perhydrocarbyl-stabilized heterobimetallic complexes [Ta(CH₂tBu)₂(μ-CHtBu)₂MCp']/[Ta(CH₂tBu)₃(μ-CtBu)MCp'] (3-M, M = Cr, Mn, Fe, Co, Ni). A combination of single-crystal X-ray diffraction, spectroscopic studies and computational investigations reveals that the species 3-M make up a series of nearly isostructural molecules, some of which ex
