1′-Methyl-3′-(4-methylbenzoyl)-4′-[5-(2-thienyl) -2-thienyl]spiro-[acenaphthylene-1,2′-pyrrolidin]-2(1H)-one

Abstract

In the title compound, C32H25NO2S 2, the mean plane through the fivemembered pyrrolidine ring, which exhibits an envelope conformation, makes dihedral angles of 82.3 (1) and 83.9 (9)° with the benzene ring and the acenaphthylene ring system, respectively. The dihedral angle between the thiophene rings is 19.0(3)°. The crystal structure shows C -H⋯π and π-π interactions [centroidcentroid distance = 3.869 (2) Å].
