Abstract
A new bis-Schiff base ligand, N,N′-bis(3,5-dimethylanil)-4-methyl-2,6-bis(imino)phenol was prepared by reacting 2,6-diformyl-4-methylphenol with 3,5-dimethylaniline. Treatment of the ligand with (DME)NiBr2 (DME = 1,2-dimethoxyethane) gave the novel dinuclear bromo-bridged complex, {di-μ-bromotetra [N,N′-bis(3,5-dimethylanil)-4-methyl-2,6-bis(imino)phenoxy]dinickel} bromide, whose crystal structure was confirmed by single crystal X-ray analysis. The calculation, via the molecular mechanics method, performs well to reproduce the crystal structure. The complex shows some activity in respect of ethene oligomerization under mild conditions with methylaluminoxane (MAO) as a co-catalyst.
