Tetra-μ₃-hydroxido-tetra­kis­[tricarbonyl­rhenium(I)] pyridine tetra­solvate

The title compound, [Re₄(μ₃-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—H...N and four inter­molecular C—H...O hydrogen-bond inter­actions are observed. Relatively strong hydrogen bonds are found between the hydrogen-bond donor (μ₃-OH) and acceptor (basic N atom of pyridine), with N...O distances between 2.586 (10) and 2.628 (10) Å. Inter­cube distances of 9.873 (2) and 12.376 (3) Å are observed.
