2-[4-(Methylsulfanyl)phenyl]naphtho[1,8-de][1,3,2]diazaborinane

Abstract

The title compound, C17H15BN2S, is one member in a series of diazaborinanes featuring substitution at the 1-, 2- and 3-positions in the nitrogen–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 interactions link the molecules into sheets which lie parallel to the bc plane. There is a π–π interaction between each pair of centrosymmetrically related sheets [centroid–centroid distance = 3.5922 (8) Å].
