Description
Summary:The title compound, C3H12B10O2 or 1‐COOH‐1,2‐closo‐C2B10H11, forms centrosymmetric dimers through intermolecular hydrogen bonding between the carboxylic acid groups, resulting in the formation of an eight‐membered ring [R(8)]. The C=O bond of the carboxylic acid group almost eclipses the unsubstituted cage C atom, with a C—C—C—O torsion angle of 2.6 (2)°.
