Crystal Structure of 6,7-Dihydro-5a,7a,13,14-tetraaza-pentaphene-5,8-dione

Abstract : The X-ray crystal structure of 6,7-dihydro-5a,7a,13,14-tetraaza-pentaphene-5,8-dione, a potential antiproliferative agent on A2058 melanoma cells, was established. It crystallizes in the monoclinic space group P21/c with cell parameters a = 24.879(3)Å, b = 6.868(2)Å, c = 26.068(4Å, α = 90, β = 110.49(2), γ = 90, V = 4172.4(15)Å3 and Z = 12. The crystal structure was refined to final values of R1 = 0.1353 and wR2 = 0.1936. An X-ray crystal structure analysis revealed that each molecule features intermolecular CArom.–H···O hydrogen bonds to form trimers.
