We usually think of hydrogen bonding as occurring between two atoms that are electronegative compared to H. But boron and H are already known to do odd.

An entirely new class of hydrogen bond that forms between a boron–hydrogen group and the aromatic, p-electron system of a benzene ring.
Diborane(6), generally known as diborane is the chemical compound consisting of boron and hydrogen with the formula B2H6. The bonding between the boron atoms and the bridging hydrogen atoms is, however, different from that in.
For example Boron is a semiconductor unlike the rest of the group 13 elements. It has properties that lie between metals and non-metals semimetals.
In contrast, qualitatively correct answers for boron clusters 7 are obtained when using the restrained fit to the electrostatic potential RESP method.
The non-classical B—H … p bond can be seen in the gas phase locking together diborane and benzene with a strength comparable to the hydrogen bonds that hold water dimers together. Dieter Cremer and Wenli Zou of the computational and theoretical chemistry group at Southern Methodist University, Dallas in the US, worked with coordination chemists from Nanjing University in China to investigate the theory of non-classical hydrogen bonds that might form between a B—H group and organic structures and to demonstrate one such system experimentally.

Boranes BoronHydrogen Compounds Introduction to Chemistry
The boranes comprise a large group of compounds with the generic formula of BxHy. Nonclassical (weak) hydrogen bonds are formed between weak Due to the slightly lower electronegativity of boron than hydrogen, the.
In a recent article, a derivative 1 of diborane B2H4(4) has been described, in which there are two bridging hydrogen atoms, with each boron atom also bonded to.
In agreement with the above-mentioned discussion on the model complexes, the calculated ESP surface of the B1 system Fig.
The name Boron comes from the Arabic and Persian words for borax, its principal ore.

According to this figure, the two B atoms and four H atoms lie in the same plane sp 3 - perpendicular to the plane of the page. E-mail: lepsik uochb.
