5-(Phenyl-diazen-yl)tropolone.

ABSTRACT: THE TITLE COMPOUND [SYSTEMATIC NAME: (E)-2-hy-droxy-5-(phenyl-diazen-yl)cyclo-hepta-2,4,6-trien-1-one], C(13)H(10)N(2)O(2), is essentially planar with an r.m.s. deviation of 0.036 (2) Å and a dihedral angle of 1.57 (8)° between the phenyl and tropolone rings. In the crystal, mol-ecules are linked by pairs of O-H⋯O hydrogen bonds into inversion dimers. The dimers are further connected by C-H⋯O hydrogen bonds and π-π stacking inter-actions, with centroid-centroid distances of 3.6934 (9) and 3.6282 (9) Å.
