The title compound consists of cholesteryl and heptanoate units, in which the six-membered rings adopt chair and twisted-boat conformations, while the five-membered ring adopts an envelope conformation. In the crystal, the molecules are aligned along the a-axis direction and stacked along the b-axis direction.

A novel triiodide phase of the formamidinium cation, CH5N2+·I3−, crystallizes in the triclinic space group P at a temperature of 100 K. The structure consists of two independent isolated triiodide ions located on inversion centers. The centrosymmetric character of I3− was additionally confirmed by the observed pronounced peaks of symmetrical oscillations of I3− at 115–116 cm−1 in Raman scattering spectra.

The structure of the product obtained from the reaction of [Zr6O4(OH)4(ib)12(H2O)]·3Hib (Hib = isobutyric acid) with Sr(NO3)2 and H2mda (H2mda=N-methyldiethanolamine) in the presence of MnCl2 and Et3N in acetonitrile was shown to be the one-dimensional coordination polymer [Sr(ib)2(H2mda)]n. Although manganese did not incorporate into the structure, its addition was the key to the isolation of a high-quality crystalline product.

In the title Schiff base hexanuclear copper(II) complex, two discrete environments are present in the structure: CuNO4 and CuNO3. Four copper(II) cations are situated in a distorted square-pyramidal environment, while two copper(II) cations are located in a slightly square-planar geometry. Three of the copper(II) cations occupy three vertices of an open cubane Cu3O4.

The structure of the title coordination polymer is determined by multiple hydrogen-bonding interactions. In the crystal, two ligands coordinate with the metal centre, generating chains, which are further connected with each other via N—H⋯O hydrogen bonds, and expanded into the final framework through additional N—H⋯O hydrogen bonds.

The structure of bis(2-methylpyridinium) tetrachlorocuprate(II) is characterized by layers formed by [C6H8N]+ and [CuCl4]2– connected through N—H⋯Cl and C—H(phenyl)⋯Cl interactions. The layers are further connected by C—H(methyl)⋯Cl interactions.

The styryl and ester substituents are displaced to opposite sides of the plane through the pyridine ring while the acetyl group is rotated well out of that plane. In the crystal, inversion-related C—H⋯O hydrogen bonds form chains extending parallel to the a-axis direction, which pack with partial intercalation of the styryl and ester substituents.

The molecules are connected in the crystal by N—H⋯O hydrogen-bond pairs along the b-axis direction as dimers with (8) and (14) ring motifs and as ribbons by intermolecular C—H⋯N hydrogen bonds. Between the ribbons, there are weak van der Waals contacts.
