1. 4,4-Difluoro-1,3,5,7-tetra-methyl-4-bora-3a,4a-diaza-s-indacene
Hai-Jun Xu Acta Crystallogr Sect E Struct Rep Online. 2008 Aug 6;64(Pt 9):o1672. doi: 10.1107/S1600536808024057.
In the title compound, C(13)H(15)BF(2)N(2), the two pyrrole rings are almost coplanar, with a dihedral angle of 3.08 (10)°. The BF(2) plane is almost perpendicular to the boron-dipyrromethene ring plane, with a dihedral angle of 89.99 (7)°.
2. 4,4-Difluoro-1,3,5,7-tetra-methyl-8-penta-fluoro-phenyl-4-bora-3a,4a-diaza-s-indacene
Xiaofeng Zhou Acta Crystallogr Sect E Struct Rep Online. 2010 Mar 6;66(Pt 4):o757. doi: 10.1107/S1600536810003703.
In the title dye compound, C(19)H(14)BF(7)N(2), the boron-dipyrromethene core lies on a crystallographic mirror plane which bis-ects the BF(2) and penta-fluoro-phenyl groups. The dihedral angle between the penta-fluoro-phenyl ring and the tricyclic system is thus 90° by symmetry. The sp(3)-hybridized B atom has a slightly distorted tetra-hedral coordination.
3. (2E)-1-(4,4''-Difluoro-5'-meth-oxy-1,1':3',1''-terphenyl-4'-yl)-3-(2-fluoro-phen-yl)prop-2-en-1-one
Hoong-Kun Fun, Wan-Sin Loh, S Samshuddin, B Narayana, B K Sarojini Acta Crystallogr Sect E Struct Rep Online. 2012 Jul 1;68(Pt 7):o2024. doi: 10.1107/S1600536812024981. Epub 2012 Jun 13.
In the title compound, C(28)H(19)F(3)O(2), the central benzene ring forms dihedral angles of 48.69 (6), 60.93 (6) and 42.06 (6)° with the fluoro-benzene rings. In the crystal, inter-molecular C-H⋯O and C-H⋯F hydrogen bonds link the mol-ecules, forming an undulating two-dimensional network parallel to the bc plane. C-H⋯π inter-actions further consolidate the crystal packing.
