The crystal structure of (3 Z)-4-[(3-hy-droxy-phen-yl)amino]-pent-3-en-2-one: helices and π-stacking inter-actions of hy-dro-gen-bridged rings
{{output}}
The title com-pound, C11H13NO2, crystallizes in the monoclinic space group P21/c with four mol-ecular units per unit cell and Z' = 1. A strong intra-molecular N-H⋯O inter-action results in a six-membered hy-dro-gen-bridged ring. An inter-molecular O-H⋯O hy-... ...
