چکیده انگلیسی
In this work, a series of five CuII coordination complexes, {[Cu(L)(dca)(OAc)]â
1.5H2O}n (1), [Cu(L)(dca)Br]2 (2), [Cu(L)(OAc)2]2 (3), [Cu(L)Cl2]2 (4), and [Cu(L)2(ClO4)2] (5), have been prepared with a novel tripyridyltriazole ligand 3,4-bis(2-pyridyl)-5-(3-pyridyl)-1,2,4-triazole (L) and different CuII sources. Single-crystal X-ray diffraction analysis reveals that these complexes show diverse 1-D (for 1), dimeric (for 2-4) and monomeric (for 5) coordination motifs, in which the L ligands exhibit different coordination fashions. These results obviously demonstrate that the structural assembly of complexes 1-5 can be exclusively dominated by the counter anions of metal salts and the auxiliary dicyanamide (dca) anion. Their thermal stabilities have also been investigated and discussed.
