Olive Corral, Anna,Kubus, Mariusz,Stroebele, Markus,Meyer, H.-Juergen
, p. 902 - 904 (2014)
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
Template assisted formation of micro- and nanotubular carbon nitride materials
Tragl, Sonja,Gibson, Katharina,Glaser, Jochen,Duppel, Viola,Simon, Arndt,Meyer, H.-Jürgen
, p. 529 - 534 (2007)
Micro- and nanotubes of an amorphous carbon nitride material were synthesized by metathesis reactions between cyanuric chloride (C3N3Cl3) and different nitrogen sources, such as Li2(CN2) or Li3(BN2). The intermediate formation of needle-shaped crystals of N(C3N3Cl2)3 was always observed in our reactions, and investigated with respect to their role as a template in the formation of tubes. Chemical analyses of the micro- and nanotubes reveal carbon to nitrogen ratios near 3:4, consistent with the suspected material C3N4. Synthesized carbon nitride materials were thermally stable up to 600?{ring operator}C in inert atmosphere. They were inspected by a number of physical measurements, mainly using TEM, EDX and IR investigations.

Stork, Ludwig,Liu, Xiaohui,Fokwa, Boniface P. T.,Dronskowski, Richard
, p. 1339 - 1342 (2007)
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.
Ni(II), Pd(II) and Pt(II) complexes of N,N-bis(3,3-dimethyl-allyl)-dithiocarbamate: Synthesis, spectroscopic characterization, antimicrobial and molecular docking studies

A potassium salt of N,N-bis(3,3-dimethyl-allyl)-dithiocarbamate has been synthesized from three step processes involving the synthesis of bis(3,3-dimethyl-allyl)-cyanamide and subsequent conversion to N,N-bis(3,3-dimethyl-allyl)amine. The dithiocarbamate ligand was obtained in a rapid exothermic reaction involving the amine and carbon disulfide in alkali medium, and its Ni(II), Pt(II) and Pd(II) complexes are reported. The characterization of the ligand and its metal complexes were carried out using various spectroscopic (FTIR, NMR, Mass) and magnetic susceptibility measurements. Square planar structures were proposed for the complexes as obtained from single crystal X-ray diffraction studies for Pt (II) and Pd(II) complexes and magnetic moment study for the Ni(II) complex. Antimicrobial susceptibility screening of the compounds was carried out using Gram positive strains: Bacillus subtilis and Staphylococcus aureus, Gram negative strains: Escherichia coli and Pseudomonas aeruginosa, and a fungal species: C. albicans. The drugs ciprofloxacin and ketoconazole were used as the reference standard drugs. The metal complexes showed significant antimicrobial activity. Thus, further study on this approach could pave a way for the development of dithiocarbamate-metal complex based antimicrobial agents.
Sulfoxide-to-sulfilimine conversions: Use of modified Burgess-type reagents

supporting information, p. 3363 - 3368 (2013/12/04)
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
Synthesis and characterization of carbon- and nitrogen-centered (Z) trigonal prismatic tungsten clusters of the formula type A[W6ZCl 18]
Weisser, Martina,Burgert, Ralf,Schnoeckel, Hansgeorg,Meyer, H.-Juergen
, p. 633 - 640 (2009/04/13)
Solid state reactions of tungsten(IV) chloride and carbodiimides (cyanamides) of lithium, sodium, calcium and silver yielded black crystalline powders of centered (Z) trigonal-prismatic tungsten cluster compounds having the general formula A[W6ZCl18] with A = Li, Na, Ca, Ag and Z = C, N. Crystal structures of the corresponding compounds were investigated by powder and single-crystal X-ray diffraction. The nature of the central atom was studied by mass spectrometry and nuclear magnetic resonance spectrometry. It turned out that the central atom can be C (in the case of the lithium and sodium compound) or N (in the case of the sodium and calcium compound).

A procedure has been developed for the synthesis of bis(arylcarbonylamino- 1H-benzimidazol-5-yl) ethers by reaction of the corresponding substituted benzoyl chloride with sodium cyanamide, followed by treatment of the resulting N-cyanobenzamide with 4-(3,4-diaminophenoxy)benzene-1,2-diamine in acid medium.
