Metallboranate und Boranatometallate. 13 [1]. Darstellung und Molekülstruktur von Uran(III)-tetrahydridoborat-3-Tetrahydrofuran

Metal Boranates and Boranatometallates. 13. Preparation and Molecular Structure of Uranium(III) Tetrahydridoborate-3-Tetrahydrofuran U(BH₄)₃ · 3 THF is slowly formed from UH₃ and diborane in the presence of tetrahydrofuran as a solvent. The compound crystallizes in the triclinic system, space group P1 , with distinct molecules in the unit cell. Its uranium atom is surrounded by three BH₄ and three tetrahydrofuran ligands in a distorted facial-octahedral arrangement. Uranium boron bond distances indicate that the BH₄ groups act as μ₃-H ligands.
