Synthesis and Structural Studies of Group 2B Transition Metal Complexes with the Bulky Nitrogen Ligand Bis[N-(2,6-diisopropylphenyl) imino]acenaphthene

Summary.

Group 2B transition metal complexes of bis[N-(2,6-diisopropylphenyl)imino]acenaphthene (o,o′-iPr₂C₆H₃-BIAN), namely, [Hg(o,o′-iPr₂C₆H₃-BIAN)Cl₂] (1), [Zn(o,o′-iPr₂C₆H₃-BIAN)₂](ClO₄)₂ (2), and [Cd(o,o′-iPr₂C₆H₃-BIAN)₂](ClO₄)₂ (3) have been synthesized and characterized. In complexes 2 and 3, IR, NMR, and conductivity measurements confirm the coordination of two (o,o′-iPr₂C₆H₃-BIAN) ligands to the metal center with two discrete perchlorate anions. X-Ray crystal structure of 1 indicates a distorted tetrahedral geometry with two nitrogen atoms from (o,o′-iPr₂C₆H₃-BIAN) ligand and two chloride atoms coordinating to the Hg(II) center.
