Abstract
To the central atom of the title compound, [HgBr(C16H18N3O2)], 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 HgII atom. The mononuclear complexes are linked into centrosymmetric dimers by non-classical intermolecular C—H⋯N hydrogen bonds and by weak Hg–η3-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.

Summary
[HgBr(C16H18N3O2)], is attached one bromide ion and a 1,3bis(2-ethoxyphenyl)triazenide ligand through one O and two. N atoms, forming a distorted square-planar geometry around the HgII atom. The mononuclear complexes are linked into centrosymmetric dimers by non-classical intermolecular C—. H N hydrogen bonds and by weak Hg–3-arene -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 edge-toface benzene ring interactions
