RESUMO

In the title compound, [HgBr(2)(C(13)H(11)NO)(2)], the Hg(II) atom adopts a four-coordinated HgN(2)Br(2) geometry, formed by two pyridine N atoms from two ligands and two bromide anions. The complex is located on a twofold axis. The coordination geometry is close to forming a see-saw (SS-4) polyhedron, the symmetry-related organic ligands being almost perpendicular; the dihedral angles between the two pyridine rings and between the two benzene rings are 85.5 (4) and 87.7 (4)°, respectively. Within the organic ligand, the pyridine ring is nearly coplanar with the benzene ring [dihedral angle = 13.1 (8)°]. In the crystal, the mol-ecular complexes are connected through weak inter-molecular C-H⋯Br contacts.
