چکیده
Mol-ecules of the title compound, Gly-β-Ala-Histamine dihydro-chloride, C(10)H(19)N(5)O(2) (2+)·2Cl(-), are linked by N-H⋯O and N-H⋯Cl hydrogen bonds into two-dimensional polymeric sheets parallel to the (011) plane, forming a stacked structure along the a axis. The parallel layers are also inter-linked alternately by different N-H⋯Cl hydrogen bonds, forming a three-dimensional framework.

Structural characterization of two tetrachloridozincate salts of 4-carboxy-1H-imidazol-3-ium: a salt hydrate and a co-crystal salt hydrate
Imidazole-containing compounds exhibit a myriad of pharmacological activities. Two tetra-chlorido-zincate salts of 4-carb-oxy-1H-imidazol-3-ium, ImHCO2H+, are reported. Bis(4-carb-oxy-1H-imidazol-3-ium) tetra-chlorido-zincate monohydrate, (C4H5N2O2)2[ZnCl4]·H2O, (I), crystallizes as a monohydrate salt, while bis-(4-carb-oxy-1H-imidazol-3-ium) tetra-chlorido-zincate bis-(1H-imidazol-3-ium-4-carb...

The title compound, (C(4)H(7)N(4)O)(2)[Bi(2)Cl(9)(C(4)H(7)N(4)O)]·H(2)O, was prepared by the reaction of bis-muth trichloride and 5-amino-1H-imidazole-4-carboxamide in a dilute HCl medium. The asymmetric unit contains two 5-amino-4-amino-carbonyl-1H-imidazol-3-ium cations, one edge-shared non-centrosymmetric biocta-hedral [Bi(2)C1(9)(C(4)H(7)N(4)O)](2-) dianion and a water mol-ecule. In the dia...

In the crystal structure of the title salt, (C(5)H(9)N(2))(2)[CuCl(4)], the organic cations and the tetrahedral [CuCl(4)] anions are linked into a three-dimensional network by N-H⋯Cl hydrogen bonds. The two 2-ethyl imidazolium cations in the asymmetric unit differ in the orientation of the ethyl group, with N-C-C-C torsion angles of -170.0 (4) and -87.6 (5)°.
