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

摘要

Group 2B transition metal complexes of bis[N-(2,6-diisopropylphenyl)imino]acenaphmene(o,o'-iPr_2C_6H_3-BIAN),namely,[Hg(o,o'-iPr_2C_6H_3-BIAN)Cl_2](1),[Zn(o,o'-iPr_2C_6U_3-BlAN)_2](ClO_4)_2(2),and[Cd(o,o'-iPr_2C_6H_3-BIAN)_2](ClO_4)_2(3)have been synthesized and characterized.In complexes 2 and 3,IR,NMR,and conductivity measurements confirm the coordination of two(0,0'-iPr_2C_6H_3-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'-Pr_2C_6H_3-BIAN)ligand and two chloride atoms coordinating to the Hg(II)center.
