Abstract

The in situ reactions of MCH₂Ph (M = Na, K or Rb) with C₆H₁₁NH₂ in toluene followed by the addition of the appropriate stoichiometric quantity of Sb(NMe₂)₃ gave the new heterobimetallic antimony(III)/alkali metal complexes [{Sb₂(NC₆H₁₁)₄}₂Na ₄] and M[{(C₆H₁₁NH)Sb(μ-NC₆H₁₁) ₂}₂Sb]·2thf (M = K or Rb). Comparison of the crystal structures of these species with those of the lithium complexes [{Sb₂(NC₆H₁₁)₄}₂Li ₄] and Li[{(C₆H₁₁NH)-Sb(μ-NC₆H₁₁) ₂}₂Sb] reveals that the geometries of these heterobimetallic cages are fundamentally dictated by the rigidity of the [Sb₂(NC₆H₁₁)₄]^2- and [{(C₆H₁₁NH)Sb(μ-NC₆H₁₁) ₂}₂Sb]^- anions.
