| Abstract: | The new rigid bidentate nitrogen ligands 1, 2‐bis(2, 5‐di‐tert‐butylphenyl)imino]acenaphthene ( 1 ) (dtb‐BIAN) and 1, 2‐bis(2‐biphenyl)imino]acenaphthene ( 2 ) (bph‐BIAN) have been synthesized by condensation of 1, 2‐acenaphthylenedione with 2, 5‐di‐tert‐butylaniline and 2‐aminobiphenyl, respectively. Reduction of 1 and 2 with magnesium and calcium results in the formation of the monomeric metal complexes (dtb‐BIAN)Mg(THF)2] ( 3 ), (bph‐BIAN)Mg(DME)2] ( 4 ), and (bph‐BIAN)Ca(THF)3] ( 5 ). Compounds 1 — 5 have been characterized by C/H analyses, IR, 1H NMR, and 13C NMR spectra, the structures of 2 , 3 , and 5 have been estimated by single crystal X‐ray diffraction. |
