The title compound, C26H20O5, crystallizes with two independent molecules (AandB) in the asymmetric unit, which differ primarily in the location of the –OCH3groups. In the crystal, the molecules form a layered structure parallel to (10-1) by C—H...O hydrogen-bonded networks. Adjacent layers are also linked by further C—H...O hydrogen bonds, forming a three-dimensional structure.

The furanose ringAadopts aoT4conformation. The fused dioxolane ringBand the substituent dioxolane ringCalso have twisted conformations. There are no strong hydrogen bonds in the crystal structure: only weak C—H...O contacts are present, which link the molecules to form a three-dimensional structure.

In the title compound, [FeIr(C5H5)(C20H14N3)Cl3]·2CH3CN, the central IrIIIatom is sixfold coordinated by three chloride ligands and three terpyridine N atoms in a slightly distorted octahedral fashion. The terpyridine ligand is functionalized at the 4′-position with a ferrocenyl group, the latter being in an eclipsed conformation. In the crystal, molecules are stacked in rows parallel to [001], with the acetonitrile solvent molecules situated between the rows. An extensive network of intra- and intermolecular C—H...Cl interactions is present, stabilizing the three-dimensional structure.

In the title compound, [Co(C10H8N2)3](C9H5N4O)2, the tris(2,2′-bipyridine)cobalt(II) dication lies across a twofold rotation axes in the space group C2/c. The N atoms of the three bipyridine ligands form a distorted octahedron around the cobalt ion. All the N atoms of the polynitrile 1,1,3,3-tetracyano-2-ethoxypropenide anions participate in C—H...N hydrogen bonds ensuring crystal cohesion and forming a three-dimensional structure. The structure is further stabilized by C—H...π(cation) and anion...π(cation) interactions.
