Chlorido[1-(2-eth-oxy-phen-yl)3-(4-nitro-phen-yl)triazenido]mercury(II)
Abstract:
In the title compound, [Hg(C(14)H(13)N(4)O(3))Cl], the Hg(II) atom is four-coordinated by one O atom and two N atoms from a tridentate 1-(2-eth-oxy-phen-yl)-3-(4-nitro-phen-yl)triazenide ligand and one terminal chloride ion in a distorted square-planar geometry. In the crystal structure, the mononuclear complexes are linked into pairs through C-H⋯O and C-H⋯Cl hydrogen bonds as well as π-π and C-H⋯π stacking inter-actions. In addition, weak Hg-μ(6)-arene π-inter-actions [mean distance of 3.667 (2) Å] are present between these dimers. The π-π stacking inter-actions are between aromatic rings with a centroid-centroid distance of 3.884 (2) Å. Moreover, edge-to-face inter-actions are present between eth-oxy CH groups and aromatic rings with H⋯π distances of 2.81 Å.

Noble Gases
The elements in group 18 are noble gases (helium, neon, argon, krypton, xenon, and radon). They earned the name “noble” because they were assumed to be nonreactive since they have filled valence shells. In 1962, Dr. Neil Bartlett at the University of British Columbia proved this assumption to be false.
