In the title compound, C(15)H(18)N(4)O(4), the 1H-imidazole ring forms a dihedral angle of 67.12 (8)° with the benzene ring. An S(6) ring motif is formed via an intra-molecular N-H⋯O hydrogen bond. In the crystal, neighbouring mol-ecules are linked by a pair of inter-molecular N-H⋯N hydrogen bonds, forming an inversion dimer. The dimers are further linked by a pair of C-H⋯O hydrogen bonds, lead...

The title compound, bis-[2,2'-dimethyl-3,3'-(butane-1,4-di-yl)diimidazol-1-ium] β-octa-molybdate(VI), (C(12)H(20)N(4))(2)[Mo(8)O(26)], was produced by hydro-thermal reaction of an acidified aqueous solution of Na(2)MoO(4) and 1,4-bis-(2-methyl-1H-imidazol-1-yl)butane (hereafter L). The structure of the title compound consists of the β-octa-molybdate anions having a center of symmetry, and proto...

The cations and anions of the title salt, 3C(6)H(16)N(+)·HSO(4) (-)·SO(4) (2-), are linked by N-H⋯O and O-H⋯O hydrogen bonds into a three-dimensional network. The hydrogensulfate ion, with a single S-O(H) bond of 1.563 (2) Å, forms a short O-H⋯O hydrogen bond [O⋯O = 2.609 (2) Å] to the sulfate ion. The hydrogensulfate ion accepts two hydrogen bonds from two cations, whereas the sulfate ion, as ...
