Crystal and molecular structure of the mercury dichloride complex with the macrocyclic dibenzo-aza-14-crown-4 ether ligand containing the embedded Di(α-pyridyl)bispidone fragment, [Hg(L)Cl2]

The crystal and molecular structure of [Hg(L)Cl2] (I), where L is dibenzo-aza-14-crown-4 ether with the embedded di(α-pyridyl)bispidone fragment, is studied by X-ray diffraction. The irregular five-vertex polyhedron of the Hg atom is formed by two Cl atoms and three N atoms of the dipyridylbispidone part of the L molecule. The O and N atoms of the macrocycle are not involved in metal coordination. The structure of complex I is compared with the structures of compounds [Zn(L)Cl2]·C2H5OH, [Co(L)(H2O)][CoCl4], and [Cu(L)(H2O)](ClO4)·2H2O studied earlier. © Pleiades Publishing, Ltd., 2016.
