A new mononuclear copper(II) complex, [CuL(ClO4)2]·CH3CN (1) has been synthesized from a symmetrical tetradentate di-Schiff base, N,N′-bis(1-pyridin-2-yl-ethylidene)-2,2-dimethylpropane-1,3-diamine (L) and characterized by X-ray crystallography. Reactions of 1 separately with ammonium thiocyanate and sodium azide yielded [CuL(NCS)]ClO4 (2) and [CuL(N3)]ClO4 (3) respectively, both of which have also...
A new 3-acetylcoumarin thiosemicarbazone (AcTsc) and its copper(II) (1), nickel(II) (2) and zinc(II) (3) complexes were synthesized and characterized by elemental analysis, UV–Vis, FT-IR, 1H and 13C NMR/EPR and mass spectroscopic techniques. The molecular structure of AcTsc, and the complexes 1 and 3 was confirmed by single crystal X-ray crystallography. The interaction of the complexes (1–3) with...
