Synthesis and crystal structure of mercury (II) complex Hg (Meca2en) I2

Abstract

The mercury (II) complex, Hg (Meca2en)I2 (1), containing bidentate Schiff base ligand  Meca2en = N,N′-bis[(E)-2-benzylidenepropylidene]ethane-1,2-diamine, has been synthesized and characterized by elemental analyses (CHN) and 1H-NMR spectroscopy. The crystal structure of 1 was determined using single-crystal X-ray diffraction. Structural investigation shows that 1 crystallizes in a monoclinic system, with space group P < /em>21/n. The Schiff base ligand Meca2en acts as a bidentate ligand coordinating via two N atoms to mercury (II) ion.
