In this study we prepared N,O‐bidentate ligands, sodium salt of 5‐(4′‐hydroxyphenylimino)quinolin‐8‐one, and sodium salt of 5,8‐quinolinequinone‐5‐(8‐hydroxy‐5‐quinolylimide) [indoöxine]. According to experimental results, formation of nickel complexes causes a large bathochromic shift of the absorption bands; in addition, these absorption bands appear in the near‐infrared region at 678‐812 nm. Also, EA, 13 C NMR, UV, and IR were performed to characterize these complexes. The above results suggest that coordination occurs via the oxygen atom of the quinoneimine moiety and the nitrogen atom of the pyridine moiety.
