Four copper(II) complexes and one copper(I) complex with pyridine-containing pyridylalkylamide ligands N-(pyridin-2-ylmethyl)pyrazine-2-carboxamide (HLpz) and N-(2-(pyridin-2-yl)ethyl)pyrazine-2-carboxamide (HLpz') were synthesized and characterized. The X-ray crystal structures of [Cu-2(L-pz)(2)(4,4'-bipy)(OTf)(2)] (1, OTf=trifluoromethanesulfonate, 4,4'-bipy=4,4'-bipyridine) and [Cu(L-pz)(py)(2)]OTfH2O (2, py=pyridine) revealed binuclear and mononuclear molecular species, respectively, while [Cu(L-pz)((2)-1,1-N-3)](n) (3), [Cu(L-pz')((2)-1,3-N-3)](n) (4), and [Cu(HLpz)Cl](n) (5) are coordination polymer 1-D chains in the solid state.

(LlE)2](BF4)·½H 2 O, have been prepared as buildingblocks and the silver(I) coordination of the ligands also probed, forming [Ag 1 (HL 1M )]BF 4 } ∞ and [Ag 1 2 (HL 1LE ) 2 ]-(BF 4 ) 2 . The [Co III (L 1E ) 2 ](BF 4 ) buildingblock has been successfully connected to a second such complex by coordination of silver(I) to a "spare" pyrazine nitrogen atom on each complex, resulting in [(Co III (LlE) 2 } 2 Ag
已经从吡嗪-2-羧酸甲酯和2-(氨基甲基)吡啶(HL 1M )或2-(2-氨基乙基)吡啶(HL 1E )制备了两个基于吡嗪的三齿酰胺配体,以探测“在吡嗪环的“背面”备用“氮原子”以与不同的金属离子配位,从而充当复合物之间的连接器。制备了两种惰性钴 (III) 配合物 [CO III (L 1M ) 2 ](BF 4 )·1 / 4 H 2 O 和 [Co III (LlE)2](BF4)·½H 2 O,作为建筑物块和配体的银 (I) 配位也被探测到,形成 [Ag 1 (HL 1M )]BF 4 } ∞ 和 [Ag 1 2 (HL 1LE ) 2 ]-(BF 4 ) 2 。[Co III (L 1E ) 2 ](BF 4 ) 结构单元通过将银 (I) 与每个复合物上的“备用”吡嗪氮原子配位,已成功连接到第二个此类复合物,对“老化”(在空气中的溶液中保存 2 天)样品的质谱和循环伏安法研究清
