2,2'-Bipyridine Mercury(II) Complexes [Hg(bpy)(NO2)X] (X = NO2 –, SCN– , CH3COO–); Π-Π Stacking In The Crystal Structure Of [Hg(bpy)(NO2)2]
2,2'-Bipyridine Mercury(II) Complexes [Hg(bpy)(NO2)X] (X = NO2 –, SCN– , CH3COO–); Π-Π Stacking In The Crystal Structure Of [Hg(bpy)(NO2)2]
|
The mercury(II) complexes of 2,2′-bipyridine (bpy), [Hg(bpy)(NO2)2], [Hg(bpy)(NO2) (CH3COO)], and [Hg(bpy)(NO2)(NCS)] have been synthesized and characterized by elemental analysis, IR, 1H NMR and 13C NMR spectroscopy. The structure of [Hg(bpy)(NO2)2] has been confirmed by X-ray crystallography. The complex is a monomer and the Hg atom has an unsymmetrical six-coordinate geometry, formed by two nitrogen atoms of the bpy ligand and four oxygen atoms of the two nitrite anions. There is a short intermolecular π-π stacking interaction between parallel aromatic rings |
