The interaction of the new tridentate ?hybrid? ligand, N-o- dimethylarsino-phenylsalicylaldimine (As-N-O), with cobalt(II) salts leads to the formation of cationic octahedral cobalt(III) complexes of the type [Co(As-N-O)2]+. No cobalt(II) complex entities containing the ligand could be isolated. With nickel(II) salts three types of octahedral complexes were obtained: (a) [Ni(As-N-O)2],H2O, (b) Ni(As-N- O)X,-xH2O (X = Cl, Br, or NCS), (c) [Ni2(As-N-O)3ClO4]. Electronic spectra, conductivity measurements, and magnetic data have been used to determine the structure of the complexes isolated. The ?hybrid? ligand appears to operate overall as a relatively weak field ligand.
