摘要:
Seven copper complexes [Cu(L1)I-2] (1), [Cu-2(L1)(2)I-2](2)[Cu-2(1 mu-I)(2)I-2] (2), [Cu(L2)I-2] (3), [Cu-2(L2)(mu-I)I(PPh3)] (4), [Cu-4(L2)(2)(mu-I)(2)I-2] (5), {[Cu(L2)I](2)[Cu-2(mu-I)(2)I-2]}(n), (6) and [Cu-2(L2)(mu-I)(2)](n) (7) have been prepared by reactions of ligands: 4'-(2-pyridyl)-2,2':6',2"-terpyridine (L1) and 4'-(3-pyridyl)-2,2':6',2"-terpyridine (L2) with CuI in hydrothermal conditions, respectively. By alternating the oxidations states of the metal centers, increasing stoichiometric metal/ligand ratio and introducing a second ligand, the compounds, were successfully developed from mononuclear (1 and 3) to multinuclear (2, 4 and 5) and polymers (6 and 7). The synthesis of these compounds may provide an approach for the construction of coordination compounds of 4'-pyridyl terpyridine with different nuclearity. (c) 2006 Elsevier B.V. All rights reserved.
