The title compound, {[Cd(3-apz2)]I2}n consists of a Cd2+ cation, iodine anions balancing the charge and bridging 3-aminopyrazole (3-apz) molecules. The Cd2+ cations are coordinated by two iodine anions and two apz ligands, generating trans-CdN4I2 octahedra, and are linked into chains by pairs of the bridging ligand. In the crystal structure, the apz ligands and iodide anions of neighboring chains are linked through interchain hydrogen bonding into a two-dimensional supramolecular network.

The structures of the four thioglycosides, all Z-configured across the C=N(CN) moiety, differ in many important torsion angles. The C—N bond lengths at the central carbon atom of the carbamimidothioate group are almost equal. Three of the four structures form layers by hydrogen bonding.

The asymmetric unit of the title compound consists of two independent ion pairs of 4-(dimethylamino)pyridin-1-ium quinolin-8-ol-5-sulfonate (HDMAP+·HqSA−) and neutral N,N-dimethylpyridin-4-amine (DMAP), forming a 1:1:1 cation:anion:neutral molecule co-crystal. The compound has a layered structure, including cation layers of HDMAP+ with DMAP and anion layers of HqSA− in the crystal. The cation and anion layers are linked by intermolecular C—H⋯O hydrogen bonds and C—H⋯π interactions.

In [UO2L(CH3OH)]n, the acetate group of the 1,2,4-triazol-based ligand bridges two uranyl cations, forming a neutral zigzag chain. A solid-state LMCT transition at 463 nm is responsible for the light-red colour of the compound.

Molecules of the aryl diester, 2-methyl-1,4-phenylene bis(3,5-dibromobenzoate), crystallized out from the melt (m.p. = 502 K/DSC). The crystal structure consists of a C—H⋯Br hydrogen-bonded network and weaker, offset π–π interactions.

Two intermediates, 4-amino-3,5-difluorobenzonitrile, C7H4F2N2 (I), and ethyl 4-amino-3,5-difluorobenzoate, C9H9F2NO2 (II), along with a visible-light-responsive azobenzene derivative, diethyl 4,4′-(diazene-1,2-diyl)bis(3,5-difluorobenzoate), C18H14F4N2O4 (III), obtained by four-step synthetic procedure, were studied using single-crystal X-ray diffraction. In the crystals of I and II, the molecules are connected by N—H⋯N, N—H⋯F and N—H⋯O hydrogen bonds, C—H⋯F short contacts, and π-stacking interactions. In the crystal of III, only stacking interactions between the molecules are found.

In the title molecule, C11H11BrO3, the dihydroindene moiety is essentially planar but with a slight twist in the saturated portion of the five-membered ring. The methoxy groups lie close to the above plane. In the crystal, π-stacking interactions between six-membered rings form stacks of molecules extending along the a-axis directions, which are linked by weak C—H⋯O and C—H⋯Br hydrogen bonds.
