摘要：

The action of ammonium fluoride on a mixture of boron and chromium in a sealed Monel ampoule at 300 degrees C yields single crystals of [CT(NH3)(6)] [CT(NH3)(2)F-4][BF4](2). The crystal structure (tetragonal, P4/mbm, Z = 2, a = 1056.0(1), c = 781.7(1) pm; R-1 = 0.0414; wR(2) = 0.1087 for 411 reflections with I-0 > 2 sigma(I)) contains [Cr(NH3)(6)](3+) and [Cr(NH3)(2)F-4](-) octahedra and twice as many [BF4](-) tetrahedra that are arranged in a quadrupled super-structure of the CsCl-type of structure.
