摘　　要：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） A, α = 98.670（7）, β = 95.069（7）, γ = 109.831（7）°, V = 1119.4（12） A3, Z = 2, Dc = 2.139 Mg/m^3, μ = 10.46 mm^-1, F（000） = 676, R = 0.043 and wR = 0.115 for 3982 observed reflections with I 〉 2σ（I）.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.
