The reactions of zirconium, yttrium, and zinc tetrahydroborate complexes NaMn(BH4)n + 1(DME)m (M = Zr, Y, Zn; DME = 1,2-diethoxyethane) with triethylcarbinol in tetrahydrofuran were studied. The products of the transformation of the BH4 groups in these reactions were isolated and identified. The reaction of triethylcarbinol with the yttrium and zirconium complexes yields bis(3-ethyl-3-pentoxy)borane BH[OC(C2H5)3]2, whereas the reaction with the zinc complex yields tris(3-ethyl-3-pentyl) borate B[OC(C 2H5)3]3. The physicochemical properties of the compounds obtained were studied. The crystal and molecular structure of B[OC(C2H5)3]3 was determined. Crystals of B[OC(C2H5)3] 3 are trigonal: a = 12.562(2) ?, c = 9.048(2) ?, Z = 2, space group P 3. The B atom is located at the crystallographic axis 3, the BO3 fragment is planar (B-O = 1.362(2) ?). The C 2H5 groups experience considerable thermal vibrations.
