Abstract

The monometallic nickelII complexes NiH2nshA2·H2O where A = water H2O, 1; pyridine py, 2; 2-picoline2-pic, 3; 3-picoline3-pic, 4; and 4-picoline4-pic, 5 and homobimetallic nickelII complexes Ni2nshA4·H2O where A = water H2O, 6; pyridine py, 7; 2-picoline2-pic, 8; 3-picoline3-pic, 9; and 4-picoline4-pic, 10, resp. have been synthesized in methanol from bis2-hydroxy-1-naphthaldehydesuccinoyldihydrazone H4nsh. The complexes have been characterized by elemental analyses, molar conductance, magnetic moment, and electronic and IR and TGA-DTA spectroscopic studies. The monometallic complexes 1 to 5 are found to have octahedral stereochemistry while complexes 6 to 10 are found to have distorted octahedral stereochemistry in which one of the NiII centres is present in N2O2 coordination sphere and another NiII centre is bonded to it through phenolate oxygen atoms via oxo-bridging.
