New ionic liquid crystals (including ionic metallomesogens) based on the pyrrolidinium core are presented. N-Methylpyrrolidine was quaternized with different mesogenic groups connected to a flexible, ω-bromosubstituted alkyl spacer. The length of the flexi ...
The syntheses, crystal structures, and adsorption/desorption properties of two novel chiral three-dimensional cyano-bridged bimetallic assemblies, {[Cu(1R,2Rchxn)2]2[Ru(CN)6]·6H2O}∞ (1) and {[Cu(1R,2Rchxn)2]12[Ru(CN)6]6·26H2O}∞ (2) (where 1R,2Rchxn = trans ...
Enantioselective synthesis of a 3-D inorganic net has been achieved leading to metal–organic frameworks built from cobalt-oxide helices in which handedness is controlled by the chirality of the linked ligand. ...
The title compound, C10H18, a decalin stereoisomer, crystallizes with Z' = 0.5 in the space group P21/n. The trans-decalin molecule is located on an inversion centre with both rings in a chair conformation, making for a quasi-flat overall shape. Despite th ...
The self-assembly properties of the proximal p-tert-butylcalix[4]dihydroquinone compound have been studied to investigate the role played by crystallization conditions in driving the formation of a previously reported cubic porous framework. In chloroform ...
The previously proposed model postulating that the incommensurately modulated KNd(MoO4)2 structure can act as a generator of the scheelite family members is validated here by refining the crystal structure of europium molybdate, Eu2(MoO4)3. ...
Three new bimetallic framework compounds, namely, (([Cd3(tn)4][Co(CN)6]2)·5H2O)∞ (1), ([Cd(tn)]3[Cr(CN)6]2)∞ (2), and ([Cu2(tn)2][Ru(CN)6]·4H2O)∞ (3), have been prepared in a very simple manner from the ligand 1,3-diaminopropane (tn), the hexacyanometalate ...
The preparation of single crystals suitable for X-ray analysis is frequently the most difficult step in structural studies of proteins.With the aid of two examples, it is shown that de novo solution of the crystallographic phase problem can be achieved at l ...
We use thermal diffuse scattering of x rays to visualize the lens-shaped portions of the Fermi surface in metallic zinc. Our interpretation of the nature of the observed scattered intensity anomalies is supported by the incorporation of inelastic x-ray sca ...
Structural studies of substituted 1,3,5-benzenetrisamides, a new family of highly versatile and efficient nucleating and clarifying agents for polymeric materials, are reported. Subtle details of the molecular structure of these species are shown to have a ...
