Preparation and crystal structure of Ba4MgF2(CN 2)4

Ba4MgF2(CN2)4 was prepared by solid state metathesis reaction from metal fluorides and sodium carbodiimide in a fused copper ampoule at 650 °C. The crystal structure was refined by single-crystal X-ray diffraction in the space group P21/c with unit cell dimensions a = 835.1(2) pm, b = 861.7(1) pm, c = 844.2(2) pm, and β = 109.09(2)°. A characteristic feature in the crystal structure of Ba 4MgF2(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. Copyright

Crystal structure determination of thallium carbodiimide, Tl2NCN

Orange-red single crystals of thallium carbodiimide, Tl2NCN, have been grown from an aqueous solution of cyanamide and thallium carbonate under strongly basic conditions. Tl2NCN crystallizes in space group P1 with a = 5.338(1), b = 6.626(2), c = 9.645(3) A, α = 98.765(4)°, β = 98.685(4)°, γ = 113.178(4)°, and Z = 3; the structure can be considered a strongly distorted antiCdI2 type. One finds two crystallographically different and irregular [NCN]Tl6 octahedra in which the Tl-N distances of the three-coordinate monovalent thallium ions lie between 2.52 and 2.72 A. The two symmetry-inequivalent NCN2- units adopt the carbodiimide shape, and the course of its molar volume as a function of the monovalent counter cation is analyzed.

Sulfoxide-to-sulfilimine conversions: Use of modified Burgess-type reagents

Sulfoxides can directly be converted into N-cyanosulfilimines using a new Burgess-type reagent. By applying this strategy with a related reagent variant, synthetically valuable NH-sulfoximines have been prepared from sulfoxides via N-protected sulfilimines. The practical three-step reaction sequence is generally high yielding and applicable to a wide range of substrates. The sulfoxide-to-sulfilimine conversion can also be performed under solvent-reduced conditions in a ball mill. Copyright
