Cover illustration: Bis[2-(2-hy­droxy­phen­yl)-1H-benzimidazol-3-ium] chloranilate was prepared as part of a study of D—H⋯A hydrogen bonding (D = N, O or C; A = N, O or Cl) in chloranilic acid–organic base systems.In the crystal, the cation and the anion are connected by a bifurcated N—H⋯(O,O) hydrogen bond, forming a 2:1 unit. The units are linked into a layer lying parallel via O—H⋯O and N—H⋯Cl hydrogen bonds. Between the layers, a C—Cl⋯π inter­action is observed. See: Ishida [IUCrData (2021). 6, x211150].

The crystal structure of the title complex, [PdCl(dppe)(INAM)]NO3.CH3CN consists of a PdII metal center in a distorted square-planar environment with hydrogen-bond inter­actions contributing to the crystal packing. An aceto­nitrile mol­ecule completes the asymmetric unit.

In the crystal of the title organic salt, the cation and the anion are connected via bifurcated N—H⋯(O,O) hydrogen bonds, forming a centrosymmetric 2:1 unit of the cation and anion. The units are further linked by O—H⋯O and N—H⋯Cl hydrogen bonds.

The title 1,2-diazole derivative is highly twisted with the dihedral angle between the pendant rings being 74.5 (1)°. In the crystal, weak C—H⋯O inter­actions feature predominantly within the three-dimensional architecture.
