In the title compound, C11H10N2O, the carboxamide group adopts a bisec
ted conformation with the carbonyl O atom eclipsing the cyclopropane r
ing, while the phenyl ring adopts an eclipsed conformation with respec
t to the C2-C3 bond of the cyclopropane ring. The crystal structure co
nsists of cyclic -CONH2 hydrogen-bonded dimers, wherein the hydrogen-b
onded molecules are related by an inversion centre. These dimers are a
rranged along the crystallographic x axis.
