Hexaborane(10)
Hexaborane(10), also known by the formula B6H10, is a borane cluster. It is one of the more stable and easily handled of the neutral boranes, making it a useful starting material for the synthesis of other boron-containing compounds.
Hexaborane(10) is a colorless or white crystalline solid under ambient conditions. It has a characteristic pungent odor. The molecule consists of a cluster of six boron atoms arranged in a distorted octahedron. Four hydrogen atoms are terminally bonded to boron atoms, and six hydrogen atoms bridge between pairs of boron atoms, resulting in the overall formula B6H10.
Synthesis of hexaborane(10) typically involves the controlled pyrolysis of diborane(6) (B2H6) under specific temperature and pressure conditions. Other methods involve the reaction of pentaborane(9) with diborane. The reaction products are complex and the desired product requires careful separation.
Hexaborane(10) is reactive towards various reagents, including bases, nucleophiles, and electrophiles. It undergoes reactions involving the breaking and forming of B-H and B-B bonds, leading to the formation of new boron clusters and derivatives. It is used in the synthesis of carboranes and other organoboron compounds.
Hexaborane(10) is a volatile compound and should be handled with care due to its toxicity and flammability. Appropriate safety precautions, including working in a well-ventilated area and using personal protective equipment, are necessary.
