Abstract: Abstract A novel panel of 1-(2,6-dibenzhydryl-3,4-difluorophenylimino)-2-aryliminoacenaphthylenes was synthesized and reacted with (DME)NiBr2 to give rise to mono and di-nuclear complexes with the general formula of LNiBr2 and L2Ni2Br4, respectively. All the ligands were characterized by… read more here.
