Abstract: The title compound, [Hg₅Br₁₀(C₇H₈N₂O)₂]_n, contains two ₃-bridging Br atoms, six ₂-bridging Br atoms and two terminal Br atoms. One Hg^II atom, lying on an inversion center, adopts a distorted octahedral geometry defined by six Br atoms. Two Hg^II atoms adopt a distorted square-pyramidal geometry by five Br atoms and the other two Hg^II atoms have a distorted tetrahedral geometry by two N atoms from a chelating O-methyl pyridine-2-carboximidate ligand and two Br atoms. The Br atoms link the Hg^II atoms into a ribbon structure along [100].
