title: Hydrogen-bonded chains in 3-(5-chloro-3-methyl-1-phenyl-1H-pyrazol-4-yl)-1-(4-methoxyphenyl)propenone and 3-(5-chloro-3-methyl-1-phenyl-1H-pyrazol-4-yl)-1-(3,4,5-trimethoxyphenyl)propenone.
abstract: Molecules of 3-(5-chloro-3-methyl-1-phenyl-1H-pyrazol-4-yl)-1-(4-methoxyphenyl)propenone, C20H17ClN2O2, (I), are linked into C(10) chains and molecules of 3-(5-chloro-3-methyl-1-phenyl-1H-pyrazol-4-yl)-1-(3,4,5-trimethoxyphenyl)propenone, C22H21ClN2O4, (II), are linked into C(14) chains, in each case by means of a single C-H...O hydrogen bond.
