Crystal Structure of 1-N-Ethylthiocarbamoyl-3,5-di(2-thienyl)-2-pyrazoline

Abstract

The title compound, 1-N-ethylthiocarbamoyl-3,5-di(2-thienyl)-2-pyrazoline, C14H15N3S3, crystallizes in the triclinic space group P1 with the following unit-cell parameters: a = 10.7560(7)A, b = 11.4836(8)A, c = 13.3007(9)A α = 77.048(5)° β = 85.563(5)°, γ = 78.261(5)° and V = 1566.72(18)A3. The crystal structure was solved with a final R = 0.0358 using 5848 independent reflections. There are two molecules in the asymmetric unit and the title compound is composed of a pyrazoline moiety containing two thiophene groups, which are oriented in opposite directions. The structure of the title compound contains two molecules in the asymmetric unit. The crystal structures are stabilized by intra and intermolecular hydrogen bonds, and C-H…π stacking interactions.
