摘要：
Ba4MgF2(CN2)(4) was prepared by solid state metathesis reaction from metal fluorides and sodium carbodiimide in a fused copper ampoule at 650 degrees C. The crystal structure was refined by single-crystal X-ray diffraction in the space group P2(1)/c with unit cell dimensions a = 835.1(2) pm, b = 861.7(1) pm, c = 844.2(2) pm, and = 109.09(2)degrees. A characteristic feature in the crystal structure of Ba4MgF2(CN2)(4) is the two-dimensional arrangement of infinite [Mg(CN2)(4/2)(CN2)(2)] layers along the bc plane of the structure. Barium and fluoride ions are situated in-between these layers.
