Abstract: 4-[(1-Hydroxycyclohexyl)methyl]-5-(2-hydroxy-1-phenylethyl)-2,2-diphenyl-1,3-dioxa-4-azonia-2-borata-4-cyclopentene benzene hemisolvate, C₂₈H₃₂BNO₄·0.5C₆H₆, contains a five-membered BONCO heterocycle with a B-envelope conformation, formed by the hydroxamate portion of the molecule. Bond lengths and angles are similar to those in related compounds. The crystal structure contains a molecule of benzene lying on a crystallographic inversion centre. The heterocycle molecules are linked by pairs of O-HO hydrogen bonds and possible O-H-interactions.
