Diborane is dimer of bh3
BH3 is a trigonal planar molecule with D3h symmetry. The experimentally determined B–H bond length is 119 pm. In the absence of other chemical species, it reacts with itself to form diborane. Thus, it is an intermediate in the preparation of diborane according to the reaction: BX3 +BH4 → HBX3 + (BH3) (X=F, Cl, … See more Trihydridoboron, also known as borane or borine, is an unstable and highly reactive molecule with the chemical formula BH 3. The preparation of borane carbonyl, BH3(CO), played an important role in exploring the … See more Molecular BH3 is believed to be a reaction intermediate in the pyrolysis of diborane to produce higher boranes: B2H6 ⇌ 2BH3 BH3 +B2H6 → B3H7 +H2 (rate determining … See more • Butterfly cluster compound See more WebSo, these computations agree with the experimental observation that $\ce{BCl3}$ does not dimerize in the way that $\ce{BH3}$ and $\ce{AlCl3}$ do. In the course of exploring the $\ce{B2Cl6}$ system, I performed a constrained optimization where I locked one $\ce{B-Cl}$ bond on each boron atom to be considerably longer than its equilibrium value ...
