The crystal structures have been determined of CH 3 NH 3 HgCl 3 , (CH 3 NH 3 ) 2 HgCl 4 , and CH 3 NH 3 Hg 2 Cl 5 . In (CH 3 NH 3 ) 2 HgCl 4 the Hg II atom is tetrahedrally coordinated by four Cl atoms with HgCl bond lengths of 2.464 to 2.478 Å. In the other two compounds the Hg II atom is involved in two short covalent HgCl bonds, forming a pseudo HgCl 2 molecule and two much longer bridging HgCl bonds. The methylammonium groups are connected by hydrogen bonds to the chlorine atoms. The nature of the hydrogen bonding scheme probably causes disorder of the methylammonium groups.
