چکیده
The asymmetric unit of the title compound, C(12)H(14)N(4)·2C(6)H(7)NO(3)S·2H(2)O, contains one half of a centrosymmetric 1,4-bis-(4,5-dihydro-1H-imidazol-2-yl)benzene (bib) molecule, one 4-amino-benzene-sulfonic acid molecule and one water mol-ecule. In the bib molecule, the imidazole ring adopts an envelope conformation. The benzene rings of bib and 4-aminobenzenesulfonic acid are oriented at a dihedral angle of 21.89 (4)°. In the crystal structure, inter-molecular N-H⋯O, O-H⋯N and O-H⋯O inter-actions link the mol-ecules into a three-dimensional network. Weak π-π contacts between the benzene and imidazole rings and between the benzene rings [centroid-centroid distances = 3.895 (1) and 3.833 (1) Å, respectively] may further stabilize the structure.

The reaction of 1,4-bis-(4,5-dihydro-1H-imidazol-2-yl)benzene (bib) with silver(I) nitrate in a 1:1 molar ratio generates the metallacyclic title complex, [Ag(2)(C(12)H(14)N(4))(2)](NO(3))(2)·2H(2)O, in which the bib ligand displays a cis configuration. Each bib ligand acts as a bidentate bridging ligand connecting a pair of Ag(I) ions to form a [2 + 2] metallamacrocycle in which the Ag⋯Ag dist...

In the hydro-thermally prepared title coordination polymer, [Ni(C(2)H(6)NO(3)S)(2)(C(12)H(10)N(4))](n), the Ni(II) ion and the 1,4-bis-(1H-imidazol-1-yl)benzene ligand occupy special positions on inversion centers. The metal ion shows a slightly distorted octa-hedral coordination geometry, being linked to two N atoms of two 1,4-bis-(imidazol-1-yl)benzene ligands and to two O and two N atoms of ...

Trypanosoma brucei, the causative agent of sleeping sickness (Human African Trypanosomiasis, HAT), contains a kinetoplast with the mitochondrial DNA (kDNA), comprising of >70% AT base pairs. This has prompted studies of drugs interacting with AT-rich DNA, such as the N-phenylbenzamide bis(2-aminoimidazoline) derivatives 1 [4-((4,5-dihydro-1H-imidazol-2-yl)amino)-N-(4-((4,5-dihydro-1H-imidazol-2...
