2-(Naphthalen-2-yl)azulene.

ABSTRACT: In the title compound, C(20)H(14), a naphthalene ring system is linked at the 2-position to the 2-C atom of the five-membered ring of an azulene unit. The compound crystallizes with two reasonably similar mol-ecules in the asymmetric unit. Neither mol-ecule is perfectly planar: the r.m.s. deviations from the best fit planes through all non-H atoms are 0.092 and 0.091?Å for the two mol-ecules. The dihedral angle between the mol-ecular planes is 49.60?(4)°. The naphthalene and azulene ring systems are inclined at dihedral angles of 6.54?(12) and 5.68?(12)° in the two mol-ecules. The crystal structure exhibits two sets of parallel layers, a typical edge-to-face herringbone packing arrangement. The structure is stabilized by an extensive series of weak C-H?? inter-actions.
