Crystal structures and Hirshfeld surface analysis of 5-amino-1-(4-meth-oxy-phen-yl)pyrazole-4-carb-ox-ylic acid and 5-amino-3-(4-meth-oxy-phen-yl)isoxazole.

The title compounds, CHNO, (I), and CHNO, (II), are commercially available and were crystallized from ethyl acetate solution. The dihedral angle between the pyrazole and phenyl rings in (I) is 52.34 (7)° and the equivalent angle between the isoxazole and phenyl rings in (II) is 7.
