title: 2-[4-(Methyl-sulfan-yl)phen-yl]naphtho[1,8-de][1,3,2]diaza-borinane.
abstract: The title compound, C(17)H(15)BN(2)S, is one member in a series of diaza-borinanes featuring substitution at the 1-, 2- and 3-positions in the nitro-gen-boron heterocycle. The dihedral angle between the mean planes of the naphthalene and phenyl ring systems is 19.86 (6)°. In the crystal structure, two C-H⋯π inter-actions link the mol-ecules into sheets which lie parallel to the bc plane. There is a π-π inter-action between each pair of centrosymmetrically related sheets [centroid-centroid distance = 3.5922 (8) Å].
