In the crystal structure of the title compound, (C(7)H(15)ClN(2))[CuCl(4)], a weak inter-molecular N-H⋯Cl hydrogen bond is observed between the organic dication and the tetrahedral [CuCl(4)](2-) anion. The organic dication is distorted, as indicated by the N-C-C-N torsion angles, which range from 16.76 (4) to 19.54 (3)°.

Under anaerobic conditions, in the dark and in the absence of electron acceptors, organic compounds are catabolized by strictly anaerobic or facultatively anaerobic bacteria by internally balanced oxidation–reduction reactions, a process called fermentation. In fermentation, the organic compound serves as both electron donor and acceptor, and adenosine triphosphate is synthesized by substrate l...

The title compound, C10H22N2 (2+)·2Br(-), was synthesized via reduction of 2,2'-dipyridyl with Ni-Al alloy/KOH, followed by separation of diastereoisomers (meso and rac) by recrystallization from ethanol. Although the two bridging C atoms are optically active, these two chiral centers adopt an (S,R) configuration; thus, the title compound contains an achiral meso form of 2,2'-bi-piperidine. Bot...

The structure of the title compound, 2C(8)H(12)NO(+)·SO(4) (2-)·3H(2)O, consists of organic layers, water mol-ecules and SO(4) (2-) anions which lie within the organic layers. In the crystal, inter-molecular N-H⋯O, N-H⋯S O-H⋯O and O-H⋯S hydrogen bonds, some of which are bifurcated, stabilize the structure.

The asymmetric unit of the title inorganic-organic hybrid compound, (C10H16N2O)[CoCl4]·H2O, consists of a tetrahedral [CoCl4](2-) anion, together with a [C10H18N2O](2+) cation and a water mol-ecule. Crystal cohesion is achieved through N-H⋯Cl, O-H⋯Cl and N-H⋯O hydrogen bonds between organic cations, inorganic anions and the water mol-ecules, building up a three-dimensional network.

In the title compound, C17H22ClNO·0.5H2O, the water mol-ecule O atom resides on a twofold rotation axis. In the organic mol-ecule, the phenol group forms an intra-molecular O-H⋯N hydrogen bond. In the crystal, pairs of organic mol-ecules are hydrogen bonded through bridging solvent water mol-ecules, forming chains along the b-axis direction.

This work presents the synthesis and studies of a red-NIR luminescent liquid crystal compound based on an octahedral metallic cluster core orthogonally bounded to six non-mesogenic organic ligands. It evidences synergetic effects between the organic and inorganic parts of the hybrid, resulting in the generation of liquid crystal properties on cooling from the isotropic melt.
