The title compound, [Zn2(C6H8O4)2(C10H9N3)2]·3H2O or {Zn2[(C5H4N)2NH]2[μ-(CH2)4(COO)2]2}·3H2O, was separated from the solvothermal reaction of zinc(II) sulfate heptahydrate, 2,2′-dipyridylamine and sodium adipate. The dinuclear metal complex has a centrosymmetric structure, with the ZnII atom adopting a highly distorted octahedral coordination sphere composed of four oxygen atoms from bridging adipato ligands and two pyridine nitrogen atoms. In the crystal, the title compound aggregates into a tri-periodic supramolecular structure through intermolecular hydrogen-bonding networks of the form O—H...O and N—H...O.

In the title compound, C15H14IN3O2·CH3OH, two aromatic rings are linked by an N-substituted hydrazide function. The dihedral angle between the aromatic rings is 10.53 (8)°. The stereochemistry about the imine function is E. The methanol molecule forms an O—H...O hydrogen bond to the hydrazide O atom. In the crystal, chains of molecules running along the c-axis direction are formed by O—H...O hydrogen bonds. Adjacent chains are linked through N—H...O hydrogen bonds and π–π stacking interactions. The intermolecular interactions in the crystal packing were investigated using Hirshfeld surface analysis, which indicated that the most significant contacts are H...H (38.2%), followed by C...H/H...C (20.6%), O...H/H...O (11.1%) and I...H/H...I (9.7%).

In the title compound, C13H11N3S2, the phenyl ring is twisted from the 1,2,4-triazole plane by 63.35 (9)° and by 47.35 (9)° from the thiophene plane. In the crystal, chains of molecules running along the c-axis direction are formed by N—H...S interactions [graph-set motif C(4)]. The 1,2,4-triazole and phenyl rings are involved in π–π stacking interactions [centroid–centroid distance = 3.4553 (10) Å]. The thiophene ring is involved in C—H...S and C—H...π interactions. The intermolecular interactions in the crystal packing were further analysed using Hirshfield surface analysis, which indicates that the most significant contacts are H...H (35.8%), followed by S...H/H...S (26.7%) and C...H/H...C (18.2%).

This study aimed to understand the impact of computer-mediated communication (CMC) tools on journalism in Vietnam by employing a quantitative-methods approach influenced by Social Presence Theory, Media Richness Theory, and Uses and Gratifications Theory. A quantitative survey was conducted with 335 journalists and other stakeholders in newsrooms. The results indicated that social presence significantly affects the adoption and efficacy of CMC tools in this unique cultural context. The study extended the Media Richness Theory by adding a cross-cultural dimension, and the Uses and Gratifications Theory sheds light on the motivations behind tool adoption. This research contributed to theory by adapting established frameworks to a new cultural environment and offers practical guidelines for media organizations in Vietnam undergoing digital transformation. Future research should explore interdisciplinary frameworks incorporating cultural, technological, and psychological factors. [ABSTRACT FROM AUTHOR]

The title compound, C 11 H 7 NS 2 , was prepared in high yield (87%) using a solvent-free microwave-assisted synthesis. The structure shows whole-mol-ecule disorder with occupancies for two orientations (A and B) of 0.4884 (10) and 0.5116 (10), respectively. The thio-phene and benzo-thia-zole rings are almost planar and make dihedral angles of 10.02 (18) and 12.54 (19)° for orientations A and B, respectively. Slipped π-π stacking between the aromatic rings, together with C-H⋯π, C-H⋯S and C-H⋯N inter-actions, result in a herringbone motif in the crystal packing.

In the title compound, C 7 H 8 N 4 S 2 , the thio-phene ring shows rotational disorder over two orientations in a 0.6957 (15):0.3043 (15) ratio. The plane of the 1,2,4-triazole ring makes a dihedral angle of 75.02 (17)° with the major-disorder component of the thiophene ring. In the crystal, two types of inversion dimers, described by the graph-set motifs R 2 2 (8) and R 2 2 (10), are formed by N-H⋯S inter-actions. Chains of mol-ecules running in the [101] direction are linked by weaker N-H⋯N inter-actions. The thio-phene ring is involved in π-π and C-H⋯π inter-actions.

The title compound, C 9 H 8 N 2 O 2 S 3 , crystallizes with two mol-ecules ( A and B ) in the asymmetric unit. Both have similar conformations (overlay r.m.s. deviation = 0.209 Å) and are linked by an N-H⋯O hydrogen bond. In both mol-ecules, the thio-phene rings show orientational disorder, with occupancy factors of 0.6727 (17) and 0.3273 (17) for mol-ecule A , and 0.7916 (19) and 0.2084 (19) for mol-ecule B . The five-membered rings make an angle of 79.7 (2)° in mol-ecule A and an angle of 66.8 (2)° in mol-ecule B . In the crystal, chains of mol-ecules running along the a -axis direction are linked by N-H⋯O hydrogen bonds. The inter-action of adjacent chains through N-H⋯O hydrogen bonds leads to two types of ring structures containing four mol-ecules and described by the graph-set motifs R 4 4 (18) and R 4 2 (14).

Reactions of (NBu4)[ReOCl4] and 3,3,3',3'-tetraalkyl-1,1'-isophthaloylbis(thioureas), H2phth(R2tu)2 where R = Et, i-Bu, in hot MeOH with the addition of Et3N give red products of the composition [ReO(OMe){phth(R2tu)2}]2 (8a, R = Et; 8b, R = i-Bu). X-ray structures of 8 reveal symmetric binuclear complexes containing two almost coplanar organic ligands, each of which coordinates to two rhenium centers via the two bidentate-O,S moieties. The octahedral coordination spheres of the rhenium atoms are completed by each one oxo and one methoxido ligand which are directed perpendicular to the plane defined by the {phth(R2tu)2}(2-) ligands. While in 8a, both methoxido ligands point to the same side of the described plane and form a syn isomer, the MeO(-) ligands in 8b are located at opposite sides and form an anti isomer. Studies in solution show that there exists a reversible equilibrium between the anti and syn isomers. Dimerization/condensation of complexes 8 with the formation of tetranuclear complexes of the composition [{ReO{phth(R2tu)2}}2O]2 (9) and/or polynuclear species is observed in solutions, which do not contain MeOH.
