Abstract:
The title compound, [Hg5Br10(C7H8N2O)2] n , contains two μ3-bridging Br atoms, six μ2-bridging Br atoms and two terminal Br atoms. One Hg(II) atom, lying on an inversion center, adopts a distorted octa-hedral 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 tetra-hedral 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].

Halogenation of Alkenes
Consider the bromination of cyclopentene. Molecular bromine is polarized in the proximity of the π electrons of cyclopentene. An electrophilic bromine atom adds across the double bond, forming a cyclic bromonium ion intermediate.
