By combining a large pi-conjugated bidentate ligand L: 3,6-dipyrazole-N-ethylcarbazole with HgI(2), an extraordinary supramolecular coordination polymer, [Hg(4)L(2)I(8)](infinity), has been prepared. The crystal structures of the ligand and its coordination polymer were determined by X-ray crystallography, which shows three varied coordination modes(More)
In the crystal structure of the title compound, C(10)H(9)N(2)O(2) (+)·Cl(-)·2H(2)O, the components are linked by O-H⋯O, N-H⋯O, O-H⋯Cl and N-H⋯Cl hydrogen bonds. In the cation, the imidazole ring is oriented at a dihedral angle of 13.67 (17)° with respect to the benzene ring. In the crystal, π-π stacking occurs between nearly parallel benzene rings, which(More)
