title: 4-(4,4-Difluoro-1,3,5,7-tetra-methyl-3a-aza-4a-azonia-4-borata-s-indacen-8-yl)benzonitrile.
abstract: The title compound, C(20)H(18)BF(2)N(3), contains one C(9)BN(2) (Bodipy) framework and one cyano-benzyl group. The Bodipy framework is essentially planar with a maximum deviation of 0.041 (2) Å. The introduction of two methyl groups at positions 1 and 7 of s-indacene in the Bodipy unit results in almost orthogonal configuration between the mean plane of the Bodipy unit and the cyano-benzyl group [dihedral angle = 89.78 (4)°].
