A supramolecular cocrystal of 2-ammino-5-nitropyridine (ANP) with 2,4-dinitrophenol (DNP) has been successfully grown by the slow evaporation solution growth technique. The crystal structure 2-amino-5-nitropyridine-2,4-dinitrophenol (ANDP) was elucidated single-crystal X-ray diffraction analysis, and it belongs to a monoclinic system centrosymmetric space group P21/n. bulk phase purity homogene...

The title compound, [RuCl(C10H14)(C11H10N4)]Cl is an Ru(II) complex in which an η (6) -p-cymene ligand, two N atoms of 3-amino-2-(phenyl-azo)pyridine and one Cl ion form a piano-stool coordination environment around the metal ion. In the crystal structure, N-H⋯Cl hydrogen bonds play an important role in the formation of the supramolecular zigzag chain along the a-axis direction. Disorder is obs...

The crystal structures of 7,7-dicyclobutyl-5-hydroxymethyl-6-oxabicyclo[3.2.1]octane-1-carboxylic acid, C17H26O4, (I), and 1-(hydroxymethyl)-7-oxaspiro[bicyclo[3.2.1]octane-6,1'-cyclopentane]-5-carboxylic acid, C13H20O4, (II), determined at 170 K, show that the conformation of the hydroxymethyl group (anti or gauche) affects the dimensionality (one- or two-dimensional) of the supramolecular str...

A novel terbium-containing fluorescent material, [Tb(CH3COO)2(H2O)3]Cl (1), has been prepared by a facile approach, i.e. an ultrasonic synthesis. Compound 1 has been structurally characterized via single-crystal X-ray diffraction and it crystallizes in the space group P21/n of the monoclinic system with four formula units in a cell. Compound 1 features a novel one-dimensional (1-D) chain-like s...

In the title salt solvate, C24H32O2P(+)·Br(-)·CHCl3, the P atom has a distorted tetra-hedral geometry, and the planes of the phenyl rings form a dihedral angle of 71.86 (14)° with one another. The bromide anion is disordered and was modelled over three positions (occupancy ratio 0.50:0.35:0.15). The crystal also contains one disordered chloro-form solvent mol-ecule that was modeled over three p...

Self-assembly relies on the ability of smaller and discrete entities to spontaneously arrange into more organized systems by means structure-encoded information. Herein, we show that design media can play a role even important than chemical design. The not only determines self-assembly pathway at single-component level, but in very narrow solvent composition, supramolecular homo-aggregate be no...

Arthropods face several key challenges in processing concentrated feedstocks of proteins (silk dope) into solid, semi-crystalline silk fibres. Strikingly, independently evolved lineages of silk-producing organisms have converged on the use of liquid crystal intermediates (mesophases) to reduce the viscosity of silk dope and assist the formation of supramolecular structure. However, the exact na...

The crystal structures of C5H14N2·HPO3·H2O (1) and C5H14N2·HPO3·2.23H2O (2) are described and compared. Compound 1 contains homochiral (S)-2-methyl piperizinium cations, hydrogen phosphite ions and water molecules. The components are linked by N–HLO and O–HLO hydrogen bonds into a three-dimensional network. In compound 2, racemic (R,S)-2-methyl piperizinium cations combine with the same anions ...
