ABSTRACT
The title compound, [Li(2)(C(18)H(22)BO)(2)(C(6)H(7)N)(2)], is a lithium dimesitylboroxide dimer in which the lithium cation is also coordinated by one mol-ecule of 2-methyl-pyridine. At the core of the structure is an Li(2)O(2) four-membered ring. The structure is centrosymmetric with an inversion centre midway between two Li atoms. Inter-molecular C-Hâ¯π inter-actions and π-π inter-actions between the 2-methyl-pyridine rings exist [centroid-centroid distance = 3.6312â (16)â Å].
