The title compound, 1,2-(COOH)2-1,2-closo-C2B 10H10·0.5C2H6O or C 4H12B10O4·0.5C 2H6O, forms a tetramer by incorporating ethanol (solvent) molecules through hydrogen bonding. Two eight-membered rings [graph set R 22(8)] are formed by hydrogen bonding between two carboxylic acid groups, whereas two ten-membered rings [R33(10)] are formed by hydrogen bonding between two carboxylic acid groups and the OH group of an ethanol molecule (solvent). Two crystallographically independent tetramers are present in the crystal structure.
