Abstract

A solid state study of the chloride complexation ability of a series of salicylaldehyde thiosemicarbazone Ni(II) complexes is presented. Complexes of general formula [Ni(5-X-HSalTSC)PPh3]Cl, where 5-X-HSalTSC−  represent the monoanion of 5-X-salicylaldhehyde thiosemicarbazones (with X = MeO, Br, NO2), were studied in comparison with the analog neutral complex [Ni(5-NO2-SalTSC)PPh3]. The crystal structure of the compounds show that the coordinated thiosemicarbazones chelate the choride anions through two N–H hydrogen bonds.
