Abstract

The charge-neutral bimetallic Zn(II)/Co(II) tridecanuclear oxocarboxylate cluster [Zn_xCo_13–x(μ₄-O)₄(O₂CPh)₁₈] (x ≈ 5.6) was synthesized under anaerobic conditions by the controlled hydrolysis of an alkylzinc carboxylate [EtZn(O₂CPh)] in the presence of cobalt(II) benzoate Co(O₂CPh)₂. The composition and molecular structure of the resulting aggregates were solved by a combination of elemental analysis, infrared spectroscopy and single-crystal X-ray diffraction.
