Magnetic and spectral studies on a binuclear Ni(II) - dimethylaminoethanethiol complex

Synthetic and Spectroscopic Investigations of Some Transition Metal Complexes of Hydroxy-Oxime Ligand

“…The electronic spectrum in nujol mull consists of bands at 530, 470 and 365 nm, however, in chloroform it shows bands at 500, 445 and 350 nm (Table 3) due to the 4 T 1g → 4 T 2g , 4 T 1g → 4 T 2g and 4 T 1g → 4 T 1g (P) transitions respectively, of a square planar configuration. 11,15,17 The ESR spectrum of a solid complex at room temperature gives an isotropic signal (g iso = 2.13), a characteristic of square planar geometry. 18 The DTA data (Table 1) show an endothermic peak at 182°C, corresponding to the melting point.…”
