a dinuclear complex, [Cu2L22(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, N3,S-chelating, while second is O, N3,S-chelation-cum-N2-bridging; and in all others thio-ligands are O, N3,S-chelating. The μeff values for the complexes lie in the range of 1.79–1.83 BM. Complexes 1, 3–6 have
乙酸铜 (II) 与 N1 取代的水杨醛缩氨基硫脲的反应 [R1R2C2=N3–N2H–C1(=S)–N1HR3;R1 = 2-HO–C6H4–, R2 = H : R3 = Me (H2L1), Et ( H2L2)] 进行了描述。在多吡啶共配体存在下,乙酸铜 (II) 与 H2L1 和 H2L2 配体反应,这导致形成单核配合物,[Cu(κ3-O, N, S-L1)(κ2-N, N- bipy)] (1),[Cu(κ3-O, N, SL)(κ2-N, N-phen)] [L = L1 (3), L2 (4)], [Cu(κ3-O, N , SL)(κ2-N, N-tmphen)] [L =L1 (5), L2 (6)] 和双核复合物,[Cu2L22(bipy)] (2) (bipy = 2, 2'-bipyridine, phen = 1, 10-菲咯啉,tmphen = 3, 4, 7
