Body Symmetry of Phylum Chordata Although chordates come in many shapes and sizes, they share the four characteristics listed above and they also all have bilateral symmetry. If you divide a chordate in half, you will get two equal pieces that are mirror images of each other.
Thiomersal features mercury (II) with a coordination number 2, i.e. two ligands are attached to Hg, the thiolate and the ethyl group. The carboxylate group is not coordinated, but confers solubility in water. Like other two-coordinate Hg(II) compounds, the coordination geometry of Hg is linear, with a 180Â° S-Hg-C angle. Typically, organomercury thiolate compounds are prepared from organomercury chlorides.
