In the title Ebselen [systematic name: (2-phenyl-1,2-benzoisoselenazol-3-(2H)-one)] analogue, C14H11NOSe, the benzisoselenazolyl moiety (r.m.s. deviation = 0.0209 Å) is nearly perpendicular to the N-arenyl ring, making a dihedral angle of 78.15 (11)°. In the crystal, molecules are linked by C-HO and SeO interactions into chains along the c-axis direction. The SeO distance [2.733 (3) Å] is longer than that in Ebselen (2.571 (3) Å].
