A series of polynuclear metal complexes, [Cu2(L1)(PPh3)4](ClO4)2 (1), [Cu3(L2)(PPh3)6](ClO4) (2), [Cu3(L3)(PPh3)6] (3), [Ag2(L1)(PPh3)4](BF4)2 (4), [Ag4(L2)2(PPh3)6] (5) and [Ag3(L3)(PPh3)5] (6), have been obtained from the reactions of the highly conjugated bridging ligands 2,3-bis(2-pyridyl)pyrazine (L1), 2,3-bis(2-tetrazoyl)pyrazine (H2L2) and 2,3-bis(2-tetrazoyl)imidazole (H3L3) with [Cu(MeCN)4]ClO4
一系列多核金属络合物,[Cu 2(L 1)(PPh 3)4 ](ClO 4)2(1),[Cu 3(L 2)(PPh 3)6 ](ClO 4)(2), [Cu 3(L 3)(PPh 3)6 ](3),[Ag 2(L 1)(PPh 3)4 ] [BF 4)2(4),[Ag 4(L 2)2(PPh 3)6 ](5)和[Ag 3(L 3)(PPh 3)5 ](6)是通过高度共轭的桥连配体2的反应获得的,3-双(2-吡啶基)吡嗪(L 1),2,3-双(2-四唑基)吡嗪(H 2 L 2)和2,3-双(2-四唑基)咪唑(H 3 L 3)与[Cu(MeCN)4 ] ClO 4和AgBF 4, 分别。它们的晶体结构已经通过X射线晶体学确定,并且已经详细研究了它们的光物理性质。配合物1和3在CH 2 Cl 2溶液中显示出光致发光,而所有配合物在固态下均显示出明显的发光。这些配合物的详细光物理研究和密度泛函理论
