摘要

Reactions of copper(II) acetate with N~1-subsitituted salicylaldehyde thiosemicarbazones [R~1R~2C~2=N~3-N~2H-C ~1(=S)-N 1HR~3;R~1 = 2-HO-C_6H_4-, R~2 = H: R~3 = Me (H2L~1), Et (H_2L~2)] are described. Copper(II) acetate was reacted with H 2L 1 and H 2L 2 ligands in the presence of polypyridyl co-ligands, and this led to the formation ofmononuclear complexes, [Cu(κ~3-O, N, S-L~1)(κ~2-N, N-bipy)] (1),[Cu(κ~3-O, N, S-L)(κ~2-N, N-phen)] [L = L~1 (3), L~2 (4)], [Cu(κ~3-O, N, S-L)(κ~2-N, N-tmphen)] [L =L~1 (5), L~2 (6)] and a dinuclear complex, [Cu_2L_2_2(bipy)] (2) (bipy = 2, 2′-bipyridine, phen = 1, 10-phenanthroline, tmphen = 3, 4, 7, 8-tetramethyl-1, 10-phenanthroline). In dinuclear complex 2, one ligand is O, N~3,S-chelating, while second is O, N~3,S-chelation-cum- N~2-bridging; and in all others thio-ligands are O, N~3,S-chelating. The μ eff values for the complexes lie in the range of 1.79-1.83 BM. Complexes 1, 3-6 have square pyramidal arrangement, whereas complex 2 has two independent molecules in the crystal lattice, and each molecule has trigonal bipyramidal square planar (5:4) coordination pair. Complexes 2, 4, and 6 showed fluorescence properties.
