Abstract

Coordination complexes of bismuth bromide, iron(II) bromide, and zinc chloride with the aceanthrylene-o-iminoquinone (ANQ) ligand, 2-((2,6-diisopropylphenyl)imino)aceanthrylen-1(2H)-one, are synthesized. The compounds have the characteristic dimeric structure due to two bridging halogen atoms connected to the metals into the four-membered cycle. The DFT-calculated energy of the bridging bonds increases in the series Bi, Fe, and Zn. The metal–ANQ interaction energy is the highest in the case of Fe and lowest for Bi. The coordination complexes of the diimine derivative (N,N'-(aceanthrylene-1,2-diylidene)bis(2,6-diisopropylaniline)) and its 7- and 8-bromosubstituted derivatives with ZnCl2 are synthesized. The lowest acceptor effect of the coordination of ZnCl2 to the carbon and hydrogen atoms in positions 7 and 8 of the anthracene fragment is found.
