Abstract
The neodymium borohydride [Li(thf)4]2[Nd2(μ-Cl)2(BH4)6(thf)2] was synthesized from neodymium chloride and lithium borohydride. The compound crystallized in the triclinic crystal system, space group 
(No. 2) with the cell constants a = 14.8613(11), b = 17.8715(13), c = 23.5846(18) Å, α = 100.760(6), β = 90.648(6) and γ = 103.294(6)°. Each neodymium atom is coordinated by three borohydride anions and a THF molecule whereas two neodymium cations are bridged through two chloro ligands. The charge of the [Nd2(μ-Cl)2(BH4)6(thf)2]2− anion, which represents the first structurally characterized binuclear mixed borohydride chlorido complex, is compensated by two [Li(thf)4]+ cations.
