The molecular packing arrangement in C13H9NO is characterized by two m
ajor interaction types. The first comprises N-H...O hydrogen bonds bet
ween glide-related molecules, with an N...O distance of 2.782 (3) angs
trom, such that each molecule is hydrogen bonded to two adjacent molec
ules. The second consists of pi-pi interactions between molecules stac
ked along the short crystal axis.
