摘要：

Four anionic ligands including 1-methyl-3(or 4)-(1-(pyridin-2-yl)-1H-pyrazol-3-yl)pyridin-1-ium iodide ([3,2???-pypzpym]I, [4,2???-pypzpym]I) and 1-methyl-3(or 4)-(3-(pyridin-2-yl)-1H-pyrazol-1-yl)pyridin-1-ium iodide ([2,3???-pypzpym]I, [2,4???-pypzpym]I) are prepared. Reaction of CuI with [3,2???-pypzpym]I affords a mononuclear complex [CuI
