Abstract

A new silylated α-diimine ligand, bis [N, N′-(4-tert-butyl-diphenylsilyl-2, 6- diisopropylphenyl) imino] acenaphthene 3, and its corresponding Ni (II) complex,{bis [N, N′- (4-tert-butyl-diphenylsilyl-2, 6-diisopropylphenyl) imino] acenaphthene} dibromonickel 4, have been synthesized and characterized. The crystal structures of 3 and 4 were determined by X-ray crystallography. In the solid state, complex 4 is a dimer with two bridging Br ...
