Abstract: In this paper we describe the moleculare and crystal structures of the Na3[Hg(Ⅱ)(edta)Cl]·6H2O (edta=ethylenediamine-N,N,N′,N′-tetraacetate). The crystal data are as follows: orthorhombic, a=8.083(2)?, b=13.870(3)?, c=38.617(5)?, V=4329.4(13)?3, Z=8, Dc=1.798 g·cm-3, μ=5.564 mm-1, F(000)=2280, R=0.0317 and Rw=0.0731 for 3883 unique reflections. In complex, the complex anion [Hg(Ⅱ)(edta)Cl]3- has a seven-coordination structure like a mono-capped trigonal-prism (C2V-MTP) in which the edta4- acts as a hexadentate ligand with four O atoms and two N atoms and a Cl- caps a quadrilateral face as a seventh ligand. It can be known that the Hg2+ which has a d10 electronic structure can form a high-coordinate compound with a hexadentate ligand (edta) because it has a big ionic radius. |
