The neodymium borohydride [Li(thf) 4 ] 2 [Nd 2 (μ‐Cl) 2 (BH 4 ) 6 (thf) 2 ] was synthesized from neodymium chloride and lithium borohydride. The compound crystallized in the triclinic crystal system, space group $P{\bar 1}$ (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 [Nd 2 (μ‐Cl) 2 (BH 4 ) 6 (thf) 2 ] 2− anion, which represents the first structurally characterized binuclear mixed borohydride chlorido complex, is compensated by two [Li(thf) 4 ] + cations.
