Crystal and molecular structure of 1‐(p‐nitrophenyl)‐2‐acetylamino‐3‐brom‐propen‐2‐on‐1, C11H9BrN2O4
Abstract M r = 313.11, orthorhombic space group Pbca, a = 8.165(1), b = 9.491(2), c = 32.207(5) Å V = 2496(1) Å 3 , D X = 1.667 Mgm −3 , Z = 8, F(000) = 1248, λ(MoKα) = 0.71069 Å, μ = 32.7 mm −1 . The crystal structure was determined by direct methods and refined by least‐squares procedure to the discrepancy factor R = 0.065. Positions of hydrogen atoms were calculated. The structure determined by x‐ray analysis confirms the chemical results.

A novel synthesis method of fibrillar trimolybdates with the use of Ag 2 Mo 3 O 10 ∙2H 2 O as a precursor has been used successfully to synthesize methylammonium trimolybdate, (CH 3 NH 3 ) 2 Mo 3 O 10 ∙H 2 O. The crystal structure of this compound was determined by X-ray powder diffraction method and refined by the Rietveld method. The compound is orthorhombic, space group P n m a (62), with a =11.241(3), b =7.585(1), and c =15.516(4) Å. The redetermined crystal structure of the precursor and the structure of the title compound are compared and discussed.

A crystal of 2,3-dimethyl-1-isopropylimidazolium bromide was prepared and its crystal structure determined at the orthorhombic space group Pnma with cell parameters a = 11.407(6), b = 7.157(4), c = 12.111(7)Å, Z = 4. Sandwiched structures were observed between the cations and the bromide anions. The π…Br and C-H…Br interactions contributed to stabilization of the crystal packing of the title compound.

The compound C 36 H 26 N 4 O 4 , a derivative of Pigment Yellow 101, is one of the few organic pigments that show fluorescence in the solid state. Since single crystals could not be grown, the structure was determined from powder data. The X-ray powder pattern could be indexed with an orthorhombic unit cell. The space group remained ambiguous. The crystal structure was solved by lattice energy minimisation in different space groups using the program CRYSCA. Subsequently, the structure was refined by the Rietveld method using restraints. The compound crystallises in a herringbone pattern in Pbcn with a = 30.117(1) Å, b = 9.723(2) Å, c = 9.511(3) Å, Z = 4 with the molecule on an inversion centre. The insolubility and the solid-state fluorescence can be explained from the crystal structure.
