在乙腈-乙醇-水混合溶剂中，用锌汞齐还原三（β-二酮基）钌（III），制备了二乙腈双（β-二酮基）钌（II）配合物。当以这种方式处理混合配体β-二酮配合物[RuL 2L ′]时，更多的供电子配体优先被两个乙腈分子取代。二乙腈配合物是合成[RuL 2L ″]型混合配体β-二酮合钌（III）配合物的有用中间体。
Diacetonitrilebis(β-diketonato)ruthenium(II) complexes were readily prepared by reducing the corresponding tris(β-diketonato)ruthenium(III) with zinc amalgam in an acetonitril–ethanol–water mixture. When a mixed-ligand β-diketonato complex [RuL2L′] is treated in this way, the more electron-donating ligand is preferentially displaced by two acetonitrile molecules. The diacetonitrile complexes are useful intermediates for the synthesis of mixed-ligand β-diketonato ruthenium( III) complexes of the type [RuL2L″].
