Abstract

The tetranuclear clusters [(CO)8Co4(μ-CO)2](μ-C2R 2), where R = CH2OH or CH2SCMe3, were prepared by the reaction of Co2(CO)8 with [Co2(CO)6][μ-C2(CH2OH) 2] in CH2Cl2 or with [Co2(CO)6][μ-C2(CH2SCMe 3)2] in hexane. According to the X-ray diffraction data, they contain the butterfly metal core. The acetylene carbon atoms (C≡C 1.420(6) or 1.421(5) Å, respectively) are bonded to all cobalt atoms, and the C-C≡C angles are decreased to 125° on average, which results in the formation of the intramolecular hydrogen bond in the case of R = CH2OH.
