The title compound, {[Mn(C₂₄H₁₄N₂O₄)(C₂₄H₁₆N₂O₄)]·0.5H₂O}_n, was obtained by the reaction of manganese nitrate with the ligand 4,4′-(4,4′-bi­pyridine-2,6-di­yl) di­benzoic acid under hydro­thermal conditions. The water O atom is located on a twofold rotation axis. The Mn²⁺ ion is hepta­coordinated by six O atoms and one N atom from the ligands. In this structure, the ligands adopts two different forms, one completely deprotonated and one with a protonated N atom (pyridinium) and a carboxylic acid function. In the crystal, N—H...O and O—H...O hydrogen bonds consolidate the packing, forming a three-dimensional framework.

2-[2-(2-Nitro­phen­yl)-4,5-diphenyl-1H-imidazol-1-yl]-3-phenyl­propan-1-ol

In the title compound, C₃₀H₂₅N₃O₃, the central imidazole ring forms dihedral angles of 77.34 (6), 12.56 (6) and 87.04 (6)°, respectively, with the o-nitro­benzene ring and the phenyl substituents in the 5- and 4-positions. The mol­ecular conformation is stabilized by weak intra­molecular C—H...π inter­actions. In the crystal, mol­ecules are linked by O—H...N hydrogen bonds, forming chains running parallel to the b-axis direction.

Crystal structure of 4-chloro-2-[(5-eth­oxy-1,3,4-thia­diazol-2-yl)meth­yl]-5-(piperidin-1-yl)pyridazin-3(2H)-one

In the title mol­ecule, C₁₄H₁₈ClN₅O₂S, the six atoms of the 1,6-di­hydro­pyridazine ring are essentially coplanar (r.m.s. deviation = 0.008 Å), and the dihedral angle between this and the 1,3,4-thia­diazole ring is 62.06 (10)°. In the crystal, centrosymmetrically related mol­ecules are linked by inter­molecular C-H-O hydrogen bonding to form a supra­molecular dimer. The terminal ethyl group is statistically disordered over two positions.
