Oxybis(dimesitylborane) dichloromethane hemisolvate

J.-H. Son and J. D. Hoefelmeyer

Abstract: The title compound, C₃₆H₄₄B₂O·0.5CH₂Cl₂, contains an almost linear O-B-O linkage [177.23 (15)°] and approximately orthogonal [interplanar angles 89.49 (5) and 80.77 (4)°] trigonal planar B centers, consistent with the previously reported non-solvated structure [Cardinet al. (1983). J. Chem. Res. (S), p. 93]. Intermolecular C-H interactions exist between mesityl groups, with a C-Hcentroid separation of 3.6535 (18) Å. The dichloromethane molecules lie on twofold rotation axes.
