The reaction of warm ethanolic solution of Ni(OAc) 2 · 4 H 2 O with S‐alkylisothiosemicarbazide‐hydrogeniodide (LR · HI; R = Me, Et, n‐Pr, n‐Bu) and pyridine yielded the octahedral bis(ligand) complexes of the general formula [Ni(LR) 2 Py 2 ]I 2 . By the isothermal heating at 95 and 110°C, these complexes were transformed into the square‐planar [Ni(LR) 2 ]I 2 (R = Me, Et) complexes and the [Ni(LR) 2 I 2 ] (R = n‐Pr, n‐Bu) complexes of distorted octahedral configuration. Besides, the Zn(LMe) 2 I 2 complex was prepared. The compounds have been characterized by elemental analysis, magnetic measurements, diffuse reflectance spectra and TG analysis.
