Synthesis and Crystal Structure of 4-Methyl-6H-pyrido[3,2,1-jk]carbazol-6-one

The synthesis, NMR and X-ray structure of 4-methyl-6H-pyrido[3,2,1- jk ]carbazol-6-one—a potential DNA intercalator are reported. The compound crystallizes in the orthorhombic P bca space group with unit cell parameters: a = 7.775(8), b = 15.113(7), c = 19.849(7) Å, V = 2332.8(3) Å 3 , Mr = 233.26 and Z = 8. In the three-dimensional arrangement of the molecules no classical hydrogen bonds were found; weak π···π and C–H···O interactions are responsible for the packing of the molecules in the crystal structure.
