Crystal structures of (5RS)-(Z)-4-[5-(furan-2-yl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl]-4-oxobut-2-enoic acid and (5RS)-(Z)-4-[5-(furan-2-yl)-3-(thiophen-2-yl)-4,5-dihydro-1H-pyrazol-1-yl]-4-oxobut-2-enoic acid

The title compounds, C17H14N2O4 (I) and C15H12N2O4S (II), possess very similar molecular geometries. In both molecules, the central 1,3,5-trisubstituted dihydropyrazole ring adopts an envelope conformation. The oxobutenoic acid fragment has an almost planar Z conformation [r.m.s. deviations of 0.049...
