In the cation of the title compound, [Ru(CH3CN)2(C10H8N2)2](BF4)2, the RuII atom is six-coordinated in a distorted octahedral geometry by the N atoms of the two 2,2′-bipyridine (bpy) ligands and two cis-arranged acetonitrile molecules. The dihedral angles formed by the pyridine rings of the bpy ligands are 8.86 (12) and 10.12 (14)°. In the crystal, the cations and anions are linked by C—HF hydrogen bonds into a three-dimensional network.

Through a diffusion reaction, cuprous bromide, triphenylphosphane and 1,3-bis(pyridin-4-yl)propane (bpp) were self-assembled to form the one-dimensional title compound, [Cu2Br2(C13H14N2)(C18H15P)2]n. Each CuI atom is coordinated by two Br atoms, one P atom from a triphenylphosphane ligand and one N atom from a bpp molecule in a distorted tetrahedral geometry. Two μ2-Br bridges connect two [Cu(PPh3)]+ units to form neutral [CuBr(PPh3)]2 dimers, which are linked by the flexible bridging bpp ligands to form a one-dimensional chain structure parallel to the c axis. The dihedral angle between the pyridine rings of the bpp ligand is 34.59 (14)°.

The title complex, [Cu3WBrOS3(C18H15P)3], a neutral heavily distorted cubane-like W/S/Cu cluster, was self-assembled from ammonium trithiotungstate(VI), cuprous bromide and triphenylphosphane in N,N-dimethylformamide. The average Cu—Br, Cu—S and W—μ3-S bond lengths are 2.731 (2), 2.318 (2) and 2.256 (2) Å, respectively, in the distorted cubane-like skeleton. The W atom exhibits tetrahedral geometry, formed by one terminal O atom and three μ3-S atoms; the W—O bond length is 1.728 (6) Å. Each Cu atom is coordinated by one P atom from a triphenylphosphane ligand, and two μ3-S and one μ3-Br atoms, forming a distorted tetrahedral coordination geometry.

The title compound, C24H22N2O4·H2O, was obtained by the reaction of 3,4-dimethoxybenzaldehyde, malononitrile and 5-phenylcyclohexane-1,3-dione. The cyclohexyl and pyran rings show half-boat and V-shaped conformations, respectively. The dihedral angle between the phenyl and benzene ring planes is 30.67 (9)°. The organic molecules are packed in a two-dimensional network parallel to the bc plane stabilized by intermolecular N—HN and N—HO hydrogen bonds.

In the cation of the title compound, [Ru(C15H10ClN3)2]Cl2·2H2O, the metal atom exhibits a distorted octahedral coordination geometry provided by the N atoms of two tridentate terpyridine ligands. The ligands are approximately planar [maximum deviation = 0.156 (5) Å] and form a dihedral angle of 87.0 (3)°. In the crystal, the cations, anions and water molecules are linked into a three-dimensional network by C—HCl, C—HO and O—HCl hydrogen bonds.

In the cation of the title organic ion pair compound, C23H20ClN2O3+·CH3O−, the cyclohexyl ring shows a half-boat conformation and the dihedral angles between two benzene rings and the pyran ring are 83.14 (7) and 73.18 (9)°. In the crystal, centrosymmetrically related cations are linked into a dimer by pairs of N—HN hydrogen bonds, generating an R22(12) ring motif. The anion interacts with the dimer through an N—HO hydrogen bond. π–π interactions between pyran rings of adjacent dimers, with a centroid–centroid distance of 3.861 (2) Å, are also observed.
