Piperazine-1,4-diium bis(hydrogen 2-propyl-1H-imidazole-4,5-dicarboxylate) monohydrate
The title compound, C(4)H(12)N(2) (2+)·2C(8)H(9)N(2)O(4) (-)·H(2)O, is a hydrated proton-transfer compound obtained from 2-propyl-1H-imidazole-4,5-dicarb-oxy-lic acid and piperazine. The asymmetric unit contains one half-cation, one anion and half a water mol-ecule. There is a centre of inversion at the centre of the cation ring and the water molecule O atom lies on a twofold rotation axis. In ...

In the crystal structure of the title compound, C(4)H(12)N(2) (2+)·C(6)H(6)O(7) (2-)·H(2)O, the cations, anions and water mol-ecules are linked by inter-molecular N-H⋯O, O-H⋯O and weak C-H⋯O hydrogen bonds into a three-dimensional network. An intra-molecular O-H⋯O inter-action occurs in the dianion.

In the title hydrated molecular salt, C(2)H(10)N(2) (2+)·2C(8)H(9)N(2)O(4) (-)·H(2)O, an intra-molecular O-H⋯O hydrogen bond occurs in the anion, forming an S(7) ring. The -CO(2) and -CO(2)H groups make dihedral angles of 3.2 (2) and 2.0 (3)°, respectively, with the five-membered ring. In the crystal, N-H⋯O, N-H⋯N and O-H⋯O hydrogen bonds lead to the formation of a three-dimensional supra-molec...

In the title compound, C(7)H(8)N(2)O(4)·H(2)O, the imidazole N atom is protonated and one of the carboxyl-ate groups is deprontonated, forming a zwitterion. The two carboxyl groups are are approximately coplanar with the imidazole ring [O-C-C-C torsion angles = -176.8 (2) and 2.9 (4)° for one group and -4.6 (3) and 176.4 (2)° for the other] and have an intra-molecular O-H⋯O hydrogen bond betwee...

In the crystal structure of the title compound, (C(10)H(15)ClN(2))[ZnCl(4)]·H(2)O, the Zn atom is coordinated by four Cl atoms in a tetrahedral geometry. The water mol-ecules and the 1-(4-chloro-phen-yl)piperazine-1,4-diium cations inter-act with the [ZnCl(4)](2-) anions through O-H⋯Cl, N-H⋯Cl, N-H⋯O and C-H⋯Cl hydrogen bonds (five simple and one bifurcated). Inter-molecular π-π stacking inter-...
