A panel of risk assessment experts reviewed a site-specific reference dose (RfD) for methylmercury for fish-eating populations on January 12, 1998. At that meeting the panel raised a number of issues and concerns which it asked the authors (ICF Kaiser International) to address in a revised document. This same panel of reviewers discussed this revised document in a conference call on February 26...

In the title mononuclear complex, [HgI(2)(C(12)H(11)NO(3))], the Hg(II) ion has a distorted trigonal-planar coordination sphere defined by two I(-) anions and the N atom of a methyl 2-(quinolin-8-yl-oxy)acetate ligand. In the crystal, face-to-face π-π stacking inter-actions, with a centroid-centroid distance of 3.563 (9) Å, are observed.

In the mol-ecule of the title compound, [HgCl(2)(C(11)H(10)N(2))], the Hg(II) atom is four-coordinated in a distorted tetra-hedral configuration by two N atoms from a 6-methyl-2,2'-bipyridine ligand and two Cl atoms. There is a π-π contact between the pyridine rings [centroid-centroid distance = 3.9758 (5) Å].
