Abstract

Stepwise interactions of photochemically generated M(CO)₅(THF) (M = Cr, Mo, W) with diferrocenylditelluride initially generated mononuclear M(CO)₅(Fc₂Te₂) followed by the bimetallic [M(CO)₅]₂(μ-Fc₂Te₂), with terminal and bridged Fc₂Te₂ moieties, respectively. On photolysis, [M(CO)₅]₂(μ-Fc₂Te₂) transformed to FcTe bridged and M-M bonded "butterfly" complexes [(CO)₄M(μ-FcTe)]₂ via the elimination of two carbonyl groups. The solid state structures and ¹²⁵Te NMR spectral data of the new complexes and a new polymorphic form of Fc₂Te₂ having remarkable intermolecular Te⋯π-Cp short contacts (av. 3.5 Å) are discussed.
