The title compound 2 crystallizes monoclinic, and the space group was determined to be C 2/c. The unit cell contains 16 molecules grouped in two sets of crystallographic independent molecules. The structure was solved by direct methods. Full matrix refinement led to R = 0.09. The molecules have C2 symmetry. The compound is composed of two five membered diazaborolidine rings joined by a boron-boron bond. The two nearly planar rings are twisted to one another by 61.6° and 56.8° respectively
