A new series of quinoxalinophenazine derivatives were synthesized in good yields by the reaction of 2,3-dibromonaphthalene-1,4-dione with different aryl-1,2-diamines in DMF as solvent at 120~130℃ or under reflux conditions. 3,12-dimethylbenzo[a]quinoxalino[2,3-c] phenazine with bidentate character reacts with mercury(Ⅱ) bromide to give suitable crystals. All products were confirmed by IR, 1H and 13C NMR, and the metal complex by single-crystal X-ray method. The crystal (C24H16Br2HgN4, Mr=720.82) belongs to the triclinic system, space group P1 with a=10.186(6), b=10.421(6), c=11.470(7) Å, α=98.670(7), β=95.069(7), γ=109.831(7)°, V=1119.4(12) Å3, Z=2, Dc=2.139 Mg/m3, μ=10.46 mm-1, F(000)=676, R=0.043 and wR=0.115 for 3982 observed reflections with I>2σ(I).
