Dimethyl(salicylaldiminato[ N:O ])cobalt complexes [CoMe 2 (2‐O‐C 6 H 1 R 1 R 2 R 3 ‐CH=NR 4 )L 2 ] (L=PMe 3 ) ( 1 ‐ 6 ) have been prepared through the reaction of [CoMe 3 (PMe 3 ) 3 ] with the corresponding substituted salicylaldimine. The complexes were characterized with IR, 1 H NMR, 13 C NMR, 31 P NMR and elemental analyses. The X‐ray crystal structure of complex 1 shows an octahedral coordination of cobalt, with two equatorial cis ‐methyl groups opposite to the planar N:O ‐chelate ring.
