title: 1-Diazo-naphthalen-2(1H)-one.
abstract: The mol-ecule of the title compound, C(10)H(6)N(2)O, is nearly planar [maximum deviation = 0.030 (1) Å]. The CN(2) moiety is almost linear, with a C-N-N angle of 175.50 (14)°. A single inter-molecular C-H⋯O hydrogen bond is observed in the crystal structure. A π-π inter-action is also observed with the shortest distance being 3.6832 (12) Å between the the centroids of the six-membered rings.
