A new series of heterobimetallic complexes [Cu(PPh₃)(NC₅H₄HC=NC₆H₄C≡CC₆H₄C≡CRu (dppe)₂Cl)X] (1a-5a) have been prepared by the reaction of trans-(NC₅H₄HC=NC₆H₄C≡CC₆H₄C≡C Ru(dppe)₂Cl) with copper salts in presence of triphenylphosphine (where X= Cl, Br, I, N₃, NCS). Our synthetic attempts and successes are discussed in combination with spectroscopic and electronic characterization of the compounds. Comparison between halides and pseudohalides were studied by thermal and electrochemical analysis where, thermally robust complexes demonstrate quasireversible redox behaviour analogous to Cu^I/II/Ru^II/III couple. Room temperature luminescence with varying electron donating and quenching abilities of halides and pseudohalides in blue-green region were observed. Concentration and solvent dependant emission displays positive solvatochromism at ambient temperature.

异双金属乙炔桥联的Cu（I）/ Ru（II）-卤化物/拟卤化物杂化配合物：合成，结构表征，发光和电化学研究

一系列新的双核配合物[铜（PPH的₃）（NC ₅ H ^ ₄ HC = NC ₆ H ^ ₄ C≡CC ₆ ħ ₄ C≡CRu（DPPE）₂ Cl）的X]（1A-5A）已经制备由的反应反式-（NC ₅ H ^ ₄ HC = NC ₆ H ^ ₄ C≡CC ₆ ħ ₄ C≡C茹（DPPE）₂ Cl）的与在三苯基膦（其中X =氯，溴，I，N的存在铜盐₃，NCS）。我们结合化合物的光谱和电子表征讨论了我们的合成尝试和成功。通过热和电化学分析研究了卤化物和假卤化物之间的比较，其中，热稳固的配合物表现出类似于Cu ^{I / II} / Ru ^{II / III}对的准可逆氧化还原行为。观察到室温下的发光具有不同的给电子和在蓝绿色区域中的卤化物和假卤化物的猝灭能力。浓度和取决于溶剂的发射在环境温度下显示正溶剂溶变色。
