Preparation and crystal structures of an ionic triple-hydrogen-bridged derivative of 9-BBN hydroborate zirconium(IV)

An ionic dinuclear triple-hydrogen-bridged 9-BBN hydroborate zirconium complex, [K(Et2O)4][{(μ-H)2BC8H14}3Zr(μ-H)3Zr{(μ-H)2BC8H14}3] (1) was formed from the reaction of Zr{(μ-H)2BC8H14}4 with KH and aniline in diethyl ether. Its molecular structure was determined. 9-BBN hydroborate ligands are coordinated to Zr atoms via bridging H atoms, with two Zr atoms bridged to each other by three hydrogens.
