The reaction of [{3,5-(CH₃)₂C₆H₃O}₂PS₂]2Ni with 1,10-phenanthroline in chloroform in 1 : 3 molar ratio
r esul ted in the format ion of ionic complex [Ni (phen) ₃ ] [S₂P(OC₆H₃ (CH₃ ) ₂ -3,5] ₂ ·CHCl ₃ in which al l the diphenyldithiophosphate ligands were displaced by N-donor bidentate ligand. The complex has been characterized by elemental analysis, magnetic moment, IR and single crystal X-ray analysis. The complex was crystallized in the triclinicspace group P¯1. Crystal structure reveals that the complex consists of cationic NiII ion chelated by six N atoms of the three N-donor bidentate ligands to form octahedral geometry whereas the two diphenyldithiophosphate counter-anions are non-coordinating, which are displaced from nickel(II) atom.
