چکیده
In the title salt, C(2)H(8)N(+)·C(10)H(6)N(3)O(5) (-), the imidazole-carboxyl-ate 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 intra-molecular carb-oxy-carboxyl-ate O-H⋯O and imidazole-oxide N-H⋯O hydrogen bonds. Iin the crystal, cation-carboxyl-ate N-H⋯O and cation-imidazole N-H⋯N hydrogen bonds result in chains along the b axis.

The water-coordinated Ni(2+) cation in the title compound, [Ni(C(10)H(5)N(3)O(4))(H(2)O)](n), assumes an octa-hedral NiN(3)O(3) coord-ination mode and is N,O-chelated by two deprotonated 2-(pyridin-4-yl)-1H-imidazole-4,5-dicarb-oxy-lic acid (HPyImDC(2-)) ligands, forming a layer structure extending in the bc plane. The chains are arranged along the b-axis direction, forming a layer structure ex...

In the zwitterionic mol-ecule of the title compound, C(10)H(7)N(3)O(4)·H(2)O, one carboxyl group is deprotonated and the pyridine N atom is protonated. The pyridinium and imidazole rings form a dihedral angle of 5.23 (1)°. An intramolecular O-H⋯O hydrogen bond occurs. In the crystal, inter-molecular N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds link the zwitterions and water mol-ecules into sheets para...

In the title zwitterionic mol-ecule, C(11)H(9)N(3)O(4), the imidazole and pyridine rings form a dihedral angle of 2.60 (2)°. An intra-molecular O-H⋯O hydrogen bond occurs. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules into inversion dimers. Weak inter-molecular C-H⋯O inter-actions further consolidate the crystal packing.

In the title compound, [Zn(C(8)H(6)N(5)O(4))(2)(H(2)O)(2)], the six-coordinate Zn(II) ion, which is located on an inversion center, has a distorted octa-hedral configuration. Each 5-carb-oxy-2-[(1H-1,2,4-triazol-1-yl)meth-yl]-1H-imidazole-4-carboxyl-ate ligand chelates to the Zn(II) ion through a triazole N atom and a carboxyl-ate O atom in the equatorial plane. The coordination sphere is compl...

The fused five- and three six-membered rings of the anthra[1,2-d]imidazole-trione part of the title compound, C27H20N4O4, show two different substituents at the imidazole N atoms, viz. an allyl group and a [3-(pyridin-4-yl)-4,5-di-hydro-isoxazol-5-yl]methyl group. The fused-ring system is approximately planar [r.m.s. deviation = 0.232 (2) Å], but is slightly buckled along the common edge of the...
