Three new boron complexes with anilido‐imine ligands, ortho ‐C 6 H 4 (NAr 1 )(CH=NAr 2 )BF 2 [Ar 1 = 2,6‐Et 2 C 6 H 3 , Ar 2 = p ‐MeC 6 H 4 ( 3a ); Ar 1 = 2,6‐ i Pr 2 C 6 H 3 , Ar 2 = p ‐MeC 6 H 4 ( 3b ); Ar 1 = 2,6‐ i Pr 2 C 6 H 3 , Ar 2 = 2,6‐Me 2 C 6 H 3 ( 3c )] were synthesized by the reaction of BF 3 (OEt 2 ) with the lithium salt of the corresponding ligands. All complexes were characterized by 1 H, 11 B, 13 C and 19 F NMR spectroscopy, elemental analyses and mass spectrometry. The molecular structures of complexes 3a – 3c were determined by X‐ray crystallography. DSC analysis of 3a – 3c demonstrates their good thermal stability. Luminescent properties of the ligands and the complexes 3a – 3c in solution and the solid state were studied. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
