Crystal structure of 4-(meth-oxy-carbon-yl)phenyl-boronic acid.

ABSTRACT: In the title compound, C8H9BO4, the meth-oxy-carbonyl group is rotated out of the plane of the benzene ring by 7.70?(6)°. In the crystal, mol-ecules are linked via pairs of O-H?O hydrogen bonds, involving the boronic acid OH groups, forming inversion dimers. The dimers are linked via O-H?O hydrogen bonds, involving a boronic acid OH group and the carbonyl O atom, forming undulating sheets parallel to (10-2). Within the sheets there are also C-H?O hydrogen bonds present, also involving the carbonyl O atom. The sheets are linked via C-H?? and offset face-to-face ?-inter-actions between inversion-related mol-ecules [inter-centroid distance = 3.7843?(16)?Å, inter-planar distance = 3.3427?(4)?Å and offset = 1.744?Å], forming a three-dimensional structure.
