Two new octahedral cobalt(III) and nickel(II) complexes, [CoL2]·ClO4 (1) and [NiL2]·H2O·NO3 (2) containing the potentially tridentate Schiff base like hydrazone ligand, N′-[1-(pyridin-2-yl)ethylidene]acetohydrazide (L) (1:1 condensation product of acetichydrazide and 2-acetylpyridine) were synthesized and characterized by spectral a well as thermal analysis and single crystal X-ray diffractometry....... hiện toàn bộ
Molecular structure and 1H, 13C NMR assignments of 1,3,5-tris(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene
Springer Science and Business Media LLC - Tập 30 - Trang 115-118 - 2000
Wei-Yin Sun, Jian Fan, Jun Hu, Kai-Bei Yu, Wen-Xia Tang
The molecule 1,3,5-tris(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene (titmb) crystallizes as a monohydrate in the monoclinic space group C2/c with a = 20.888(4), b = 13.220(2), c = 14.385(2) Å, β = 90.36(1)°. Two of three imidazole groups are on one side of the central benzene ring, and the other one is on the opposite side. The crystal packing of titmb is stabilized by O-H--N hydrogen bonding betw...... hiện toàn bộ
The Crystal Structure of Bis(diethylammonium) Hexachloridoplumbate(IV) Derived From Powder Diffraction Data and its Relation to Structurally Related Hexachloridometallate Salts
Springer Science and Business Media LLC - Tập 47 - Trang 173-181 - 2017
A. Ouasri, A. Rhandour, S. Schloots, G. J. Reiss
Bis(diethylammonium) hexachloridoplumbate(IV) was obtained by the reaction of PbO2 and (C2H5)2NH2Cl in hydrochloric acid solution. From the obtained crystalline powder a Rietveld refinement verified the structure of bis(diethylammonium) hexachloridoplumbate(IV) to be isotypic to the corresponding tin(IV) and platinum(IV) salts. The hexachloridoplumbate(IV) anions act as fourfold hydrogen bond acce...... hiện toàn bộ

Hydrogen bonding in 2-hydroxy((di)thio)benzoates. III. IR and NMR spectra of 2,6-dimethylpiperidinium and tetraethylammonium salts
Springer Science and Business Media LLC - Tập 23 - Trang 403-406 - 1993
Werner Mikenda, Erich Steinwender, Hans Peter Kählig
Solid state ir and solution ir and nmr data are reported for 2,6-dimethylpiperidinium and tetraethylammonium salts of 2-hydroxybenzoic, 2-hydroxythiobenzoic and 2-hydroxydithiobenzoic acid. The solid state ¯v(OH) frequencies, range from 2800 to 2300 cm−1 and decrease within the series thiocarboxylate (O-H⋯O)>dithiocarboxylate (O-H⋯S)>carboxylate (O-H⋯O)>thiocarboxylate (O-H⋯S), reflect the differe...... hiện toàn bộ
Crystal structure of strontium potassium arsenate octahydrate

The crystal structure of strontium potassium arsenate octahydrate, SrKAsO4·8H2O, has been determined by single crystal X-ray diffraction. The crystals are tetragonal, a = 7.144(1), c = 23.613(2) Å, space group I41md (No. 109), Z = 4, V = 1205.1(1) Å3, and d c = 2.258 g cm−3. All cations and anions in this compound are completely surrounded by water molecules. Sr2+ and K+ ions are each coordinated ...... hiện toàn bộ
Crystallographic and Computational Studies of Non-Covalent Interactions of Molecular Clips with a Series of Small Solvent Molecules
Springer Science and Business Media LLC - Tập 48 - Trang 131-137 - 2018
Madhubabu Alaparthi, Dayton Jonathan Vogel, Andrew G. Sykes
Molecular clips hold the potential of self-association and the ability to form host–guest complexes. Here we describe the synthesis of a 1,2-dimethoxyphenyl terminated glycoluril molecular clip (2) that binds with smaller solvent molecules by π⋯H–C and C=O⋯H–O non-covalent interactions. We obtained single crystals of 2 and 2 + CH2Cl2, CH3OH, CH3CN, and DMF solvents complexed within the clip. These...... hiện toàn bộ
