Intermolecular Interactions of 3,5-bis(4-Methoxyphenyl)-4,5-dihydro-1H-pyrazole-1-carbothioamide in a Cocrystal with 1,3-bis(4-Methoxyphenyl)prop-2-en-1-one and Dimethylformamide Solvate

Two new multicomponent crystals consisting of 3,5-bis(4-methoxyphenyl)-4,5-dihydro-1H-pyrazole-1-carbothioamide (1) with 1,3-bis(4-methoxyphenyl)prop-2-en-1-one (2) and dimethylformamide (DMF), both in 1:1 ratio, prepared structurally characterized. The occurrence 1 different crystal structures enabled a comparison hydrogen bonding contacts between the two as well known structure pure 1. backbone molecule was similar but orientation methoxy groups varied. Molecule involved various combinations possible contacts, including N–H…O=C, N–H…OMe, N–H…S. Both N–H hydrogens cocrystal (1–2) solvate (1-DMF) participated only one atom took part S accepted 1–2 not that 1-DMF solvate. oxygen atoms acted acceptors 1, whereas none 1–2.
