Bis(μ-dimesitylborinato-κ2O:O)bis[(2-methylpyridine-κN)lithium]

Abstract

The title compound, [Li2(C18H22BO)2(C6H7N)2], is a lithium dimesitylboroxide dimer in which the lithium cation is also coordinated by one molecule of 2-methylpyridine. At the core of the structure is an Li2O2 four-membered ring. The structure is centrosymmetric with an inversion centre midway between two Li atoms. Intermolecular C—H...π interactions and π–π interactions between the 2-methylpyridine rings exist [centroid–centroid distance = 3.6312 (16) Å].
