以吡嗪 (pyrazine) 與雙咪唑 (imidazole) 所合成之新的具有多配位的咪唑鹽類2,3-di(1-methylimidazolium)pyrazine-imine dihexafluorophosphate (1a)，2,6-di(1-methylimidazolium)pyrazine dichloride (1b)，及2,6-di(1-methylimidazolium)pyrazine dihexafluorophosphate (1c)。將1c在室溫下與氧化銀先進行配位反應形成 Dis[2,6-di(1-methylimidazol-2-ylidene)pyrazine] disilver(I) dihexafluorophosphate (2c)。 然後利用2c與CuI 進行transmetalation 產生Dis[2,6-di(1-methylimidazol-2-ylidene)pyrazine] dicopper(I) dihexafluorophosphate (3c)，其結構為兩個配位基與兩銅原子配位形成dinuclear的型態。此類型Cu(I)-NHC complexes可應用於在 alkane functionalization。
另外將1b與RuCl3。xH2O 在溶劑中加熱迴流，可得到Bis[2,6-di(1-methylimidazol-2-ylidene)pyrazine] ruthenium(II) dichloride (2b)，再加入NH4PF6置換產生Bis[2,6-di(1-methylimidazol-2-ylidene)pyrazine] ruthenium(II) dihexafluorophosphate (4c)。此產物為兩配位基以六個配位點螯合形成的 distorted octahedral 型態。此產物具放光性，可應用於 photosensitizer 上。
