Abstract
New complexes of trivalent nickel and copper, viz. Ni(III)(Lcdt)(2)X (X = B r, I and Lcdt = 4-methylpiperidinecarbodithioate anion (4-MePipdcdt) and 2, 6-dimethylpiperidinecarbodithioate anion (2,6-Me(2)Pipdcdt) and Cu(III)(Lcd t)(n)X-m (n = 2, m = 1 when X = I and n = 1, m = 2 when X = Br and Lcdt = t he anions: 3 -methylpiperidinecarbodithioate (3-MePipdcdt), 4-MePipdcdt and 2,6-Me(2)Pipdcdt have been prepared by oxidation of M(Lcdt)(2) (M = Ni(II) and Cu(II)) with halogen X-2 in suitable media. The complexes have been ch aracterised by elemental analyses, infrared and electronic spectral and roo m-temperature magnetic susceptibility studies. For nickel(III) carbodithioa tes either a square-planar or square-pyramidal structure has been assigned and for the copper(III) carbodithioates,the presence of a mixture of single t (S = 0) and triplet (S = 1) forms of square-planar species has been propo sed.
