Synthesis and Crystal Structure of 5,7,12,13b,13c,14-Hexahydro-1,4,-dibromo-8,11-dimethoxy-13b,13c-bis(ethoxycarbonyl)-6H,13H-5a,6a,12a,13a-tetra azbenz[5,6]azuleno[2,1,8-ija]benz[f]azulene-6,13-dione

摘要

The title compound has been synthesized by the reaction of 4 with 1,4-dimethoxybenzene. The yielded product 5 was investigated with X-ray crystallographic, NMR, EI-MS, and IR techniques. The crystal belongs to a monoclinic system, space group P21/c with unit cell parameters a = 12.7790(17) ?, b = 21.565(3) ?, c = 12.2544(16) ?, α = 90°, β = 107.014(2)°, γ = 90°, V = 3229.3(7) ?3, Z = 4, Dc = 1.661, Mr = 807.32, μ = 2.732 mm?1, F(000) = 1632, R1 = 0.0540 and wR2 = 0.0989.
