Tetra-₃-hydroxido-tetrakis[tricarbonylrhenium(I)] pyridine tetrasolvate

M. Schutte, A. Brink, H. G. Visser and A. Roodt

Abstract: The title compound, [Re₄(₃-OH)₄(CO)₁₂]·4C₅H₅N, crystallizes with one tetranuclear rhenium(I) cubane-like molecule and four pyridine molecules in the asymmetric unit. The coordination environment of each Re^I atom is distorted octahedral. Four intramolecular O-HN and four intermolecular C-HO hydrogen-bond interactions are observed. Relatively strong hydrogen bonds are found between the hydrogen-bond donor (₃-OH) and acceptor (basic N atom of pyridine), with NO distances between 2.586 (10) and 2.628 (10) Å. Intercube distances of 9.873 (2) and 12.376 (3) Å are observed.
