Kc. Malhotra et al., ADDUCTS OF 4-T-BUTYLPHENOXO COMPLEXES OF OXOVANADIUM(V) WITH 2-CYANOPYRIDINE, 3-CYANOPYRIDINE AND 4-CYANOPYRIDINE, Journal of the Indian Chemical Society, 75(3), 1998, pp. 137-139
4-t-Butylphenoxo-complexes of oxovanadium(v) of composition VOCl3-x(OC
6H4But-4)(x), where x = 1 --> 3, react with 2-, 3- and 4-cyanopyridine
s to give adducts of varying composition. 2-Cyanopyridine forms adduct
of 1 : 1 composition, coordinating simultaneously through pyridine as
well as nitrile nitrogens of the ligand, while 3- and 4-cyanopyridine
s forms adducts of 1 : 2 composition (metal : ligand) coordinating thr
ough only pyridine nitrogen of the ligand.
