Abstract
Compounds of the type [N(2amet)pipzH3)-[HgX4]X (N(2amet)pipzH3 = N-(2-ammoniumethyl)-piperazinium trication; X = Cl, Br) have been prepared and characterized by means of Raman and far-IR spectroscopy. The crystal determination of [N(2amet)pipzH3)-[HgCl4] Cl shows that it is composed of discrete monomeric [HgCl4]2− units, chloride and [N(2amet)pipzH3]3+ ions. Co-ordination around the mercury atom is distorted tetrahedron with two shorter and two longer HgCl distances (av. 2440(9) and av. 2.556(9) Å, respectively).
