A comparative study of Ni(II) with N-H, N-ō, S-ō, ō-ō donar atoms as secondary ligand

Abstract

In this paper a comparative study is carried out on binary, NiL2, and ternary NiAL complexes. Where A=2, 24 bipyridyl amine or 2.2 bipyridyl and L=N-N or N-Ō or S-Ō or Ō-Ō donating ligand. The order of stabilities of binary & ternary complexes is explained on the basicities of the ligand & ring size of the chelate. The sequence in order is explained in terms of ML π interaction, size of chelate ring & steric factor. The same order is followed both by ternary complexes and binary complexes.
