摘　　要：各种各样的氨基多羧酸类配合物多年来一直是化学家们较为感兴趣的研究课题之一［１～４］。特别是近年来，氨基多羧酸类配体作为一些有毒重金属的排泄剂［５］和与一些放射性金属离子形成配合物后作为核医学的显影剂［６］等方面得到了广泛的应用。金属Ｈｇ是有毒的，一般...In this paper we describe the moleculare and crystal structures of the Na 3[Hg(Ⅱ)(edta)Cl]·6H 2O (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, D c=1 798 g·cm -3 , μ =5 564 mm -1 , F (000)=2280, R =0 0317 and R w=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 ( C 2V MTP) in which the edta 4- 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 Hg 2+ which has a d 10 electronic structure can form a high coordinate compound with a hexadentate ligand (edta) because it has a big ionic radius
