✦ Synopsis
The X-ray crystal structures of the complexes C6H5CHOoBF31 and H2C=C(CH3)CHO.BF32 reveal that the BF3 is coordinated to the oxygen lone pair which is syn to the formyl proton and, further, that the formyl proton and one B-F bond are in plane (eclipsed) with respect to the C-O-B triad, as shown in 1.
