The neodymium borohydride [Li(thf)(4)](2)[Nd-2(mu-Cl)(2)(BH4)(6)(thf)(2)] was synthesized from neodymium chloride and lithium borohydride. The compound crystallized in the triclinic crystal system, space group P (1) over bar (No. 2) with the cell constants a = 14.8613(11), b = 17.8715(13), c = 23.5846(18) angstrom, alpha = 100.760(6), beta = 90.648(6) and gamma = 103.294(6)degrees. 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(mu-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.
