A heterocyclic molecule of a novel class with a multiple ring system has been synthesized using a new and simple strategy and acetic acid as catalyst. The structure of the title molecule has been determined by spectral analysis and single crystal X-ray diffraction analysis. The compound crystallizes in monoclinic system, space group P21/c, with two crystallographically independent molecules in an asymmetric unit. The two molecules show close comparable geometric parameters and a similar conformation of fused-ring systems. The crystal structure is stabilized by a combination of N–H⋅⋅⋅O and C–H⋅⋅⋅O hydrogen bonds, where independent molecules display equivalent interaction patterns.
