[1,3-Bis(2-ethoxy­phen­yl)triazenido]bromidomercury(II)

To the central atom of the title compound, [HgBr(C(16)H(18)N(3)O(2))], is attached one bromide ion and a 1,3-bis­(2-ethoxy­phen­yl)triazenide ligand through one O and two N atoms, forming a distorted square-planar geometry around the Hg(II) atom. The mononuclear complexes are linked into centrosymmetric dimers by non-classical inter­molecular C—H⋯N hydrogen bonds and by weak Hg–η(3)-arene π-inter­actions [mean distance = 3.434 (3) Å]. The resulting dimeric units are assembled into zigzag chains by translation along the crystallographic c axis through secondary C—H⋯π edge-to-face benzene ring inter­actions.
