The crystal is of orthorhombic, space group P212121 with a = 5.931(1), b = 12.413(1), c = 28.102(2) A, V= 2090.4(3) A3, Z = 4, Dc = 1.358 g/cm3, F(000) = 888, μ= 0.186 mm-1, MoKa radiation (2 = 0.71073), R = 0.041 and wR = 0.105 for 4567 observed reflections with I 〉 2σ(I). X-ray diffraction analysis reveals that the indole and thiophene rings are not coplanar with a dihedral angle of 46.26(5)°. Intramolecular and intermolecular N-H'..O hydrogen bonds together with C-H...π interations can be observed in the lattice.  相似文献

X-ray crystallographic study showed that compound 1 is constructed from [As6V15O42(H2O)]^6- polyoxoanions linked together by novel [Zn(dien)(Hdien)]^3+ complex fragments via hydrogen bonds into a three-dimensional network. Variable temperature susceptibility measurement demonstrates the presence of antiferromagnetic interaction between V^IV cations in 1.  相似文献

We have devised a convenient procedure for the synthesis of fused organic salts resulting from 1:1 proton-transfer, using an amine and a derivative ofbenzenesulfonic acid. The synthesized salts have a number of applications ranging from their consumption as eco-friendly solvents and catalysts in organic syntheses, to being used as efficient precursors for the production of sulfa drugs. Structures of compounds 3-chloroanilinium 2,4-dinitrobenzenesulfonate (CA-DNBS) and triethylaminium 2,4,6-trimethylbenzenesulfonate (TEA-TMBS) were determined by single-crystal X-ray diffraction studies and infrared spectroscopy.  相似文献

A total of 30431 reflections were collected, of which 3083 were independent (Rint = 0.0605). S is 1.182. The title compound presents a 3-D structure via intermolecular hydrogen bonds among [PW12O40]3- polyanions and pyridine-4-carboxylic acid ligands. The ultraviolet and luminescence spectra have been studied at room temperature, of which the purple fluorescent emission is located at 363 nm when excited at 264 nm. Fluorescent emission of the compound derives from the π-π* transitions in the pyridine-4-carboxylic acid ligands.  相似文献
