In the asymmetric unit of the title compound, [HgCl2(C16H14N4S)], the Hg(II) cation is linked to two Cl atoms and two imidazole N atoms of the chelating bis-[(1H-benzimidazol-2-yl)meth-yl]sulfane ligand, forming a slightly distorted tetra-hedral environment. The substitued imidazole rings of the ligand are almost perfectly planar [with maximum deviations of 0.017 (3) and 0.012 (3) Å] and form a...

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 chemically dynamic spermine-based polymer: polyspermine imidazole-4, 5-amide (PSIA, Mw > 7 kDa) was designed, synthesized, and evaluated in terms of its ability to deliver nucleic acids. This polymer was made from an endogenous monomer professionally condensing genes in sperms, spermine, and a known safety drug metabolite, imidazole-4, 5-dicarboxylic acid, through a bis-amide bond conjugated ...
