Ethane-1,2-diaminium bis(4-carboxy-2-propyl-1H-imidazole-5-carboxyate) monohydrate
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...
متن کامل4,5-Bis(1H-tetrazol-5-yl)-1H-imidazole monohydrate
The title compound, C(5)H(4)N(10)·H(2)O, is composed of three five-membered rings that are essentially coplanar, the dihedral angles between the imidazole ring and the tetra-zole rings being 3.5 (2) and 3.0 (2)°. In the crystal, inter-molecular O-H⋯N, N-H⋯O and N-H⋯N hydrogen bonds lead to the formation of a three-dimensional network. An intra-molecular N-H⋯N hydrogen bond is also present.
متن کاملPiperazine-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 ...
متن کامل2-Ethyl-1H-imidazole-4-carboxylate monohydrate
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...
