Reactions of nickel(II) acetate with N1-substituted pyridine-2-carbaldehyde- and salicylaldehyde thiosemicarbazones, {R1(H)C2{double bond, long}N3-N2(H)-C1({double bond, long}S)-N1HR2}, have formed complexes of stoichiometry: (i) [Ni(κ3-N4, N3, S-pytscN1-R2)2] {R1 = C5H5N, R2 = Me, 1; Et, 2; Ph, 3} and (ii) [Ni(κ3-O, N3, S-stscN1-R2)L] {R1 = 2-HOC6H4, R2, L: Me, PPh3, 4; Et, PPh3, 5, Me, py, 6; Ph, py, 7}. Likewise copper(II) has formed complexes of stoichiometry: [Cu(κ3-O, N3, S-stscN1-R2)py] {R1 = 2-HOC6H4, R2 = Me, 8; Ph, 9}. These complexes have been characterized with the help of analytical data, spectroscopic techniques {IR, 1H and 31P NMR, electronic absorption} and single crystal X-ray crystallography (1, 2, 4, 6 and 8). The complexes have either distorted octahedral (1-3) or square planar geometries (4-9). The magnetic susceptibility measurements revealed that complexes 1-3, 8 and 9 are paramagnetic.
