(R)-N-(3-Meth­oxy­phen­yl)-tert-butane­sulfinamide

The title compound, C₁₁H₁₇NO₂S, was obtained by the reaction of (R)-tert-butane­sulfinamide with 3-meth­oxy­phenyl bromide in toluene. In the crystal, mol­ecules inter­act head-to-tail through N—H...O and C—H...O hydrogen bonds, forming one-dimensional chains parallel to the a axis.

catena-Poly[[(acetato-κ²O,O′)[2-(4-oxo-1,4-dihydro­quinolin-1-yl)acetato-κO¹]copper(II)]-μ-4,4′-bipyridine-κ²N:N′]

In the title compound, [Cu(C₁₁H₈NO₃)(CH₃COO)(C₁₀H₈N₂)]_n, the Cu^II ion is six-coordinated by two N atoms from two 4,4′-bipyridine ligands, four O atoms from one acetate ligand, one 2-(4-oxo-1,4-dihydro­quinolin-1-yl)acetate ligand and one water mol­ecule in a distorted octa­hedral geometry. The 4,4′-bipyridine ligands inter­connect [Cu(C₁₁H₈NO₃)(CH₃COO)] units, giving rise to a chain along [010]. These chains are further linked to each other by O—H...O hydrogen bonds, leading to a two-dimensional supra­molecular network parallel to (100).

Dimethyl­ammonium 5-carb­oxy-2-(1-oxo-1λ⁵-pyridin-2-yl)-1H-imidazole-4-car­box­yl­ate

In the title salt, C₂H₈N⁺·C₁₀H₆N₃O₅⁻, the imidazole­carboxyl­ate anion is essentially planar [maximum deviation from the least-squares plane = 0.046 (5) Å], with a dihedral angle between the rings of 2.7 (2)°. This conformation is maintained by the presence of both intra­molecular carb­oxy–carboxyl­ate O—H...O and imidazole–oxide N—H...O hydrogen bonds. Iin the crystal, cation–carboxyl­ate N—H...O and cation–imidazole N—H...N hydrogen bonds result in chains along the b axis.
