中文摘要：
以6–（4–甲基磷酸二乙酯苯基）–2,2＇–二联吡啶（L）与[Cu（CH3CN）4]BF4反应,得到了一种单核铜（Ⅰ）配合物[CuL2]BF4（1）。晶体结构表明,化合物1中二个配体提供四个N原子与Cu（Ⅰ）配位,中心金属离子Cu（Ⅰ）呈扭曲四面体构型。该配合物在426nm与527nm（sh）的低能吸收可归属为MLCT跃迁。电化学研究表明1具有大的Cu（Ⅱ）/Cu（Ⅰ）氧化还原电位（E1/2=0.49V,相对比饱和甘汞电极）,表明1有很好的抗氧化能力。
英文摘要：
A new mononuclear copper（I）complex,[CuL2]BF4（1）,where L is 6–（4–diethylmethylphosphonatephenyl）-2,2＇-bipyridine,was synthesized and characterized.The X-ray crystal indicated that the copper（I）center coordinated with four N atoms from two ligands,and adopted a distorted tetrahedron geometry.1showed low-lying absorption spectra,locating at 426and 527nm（sh）,and was assigned to metal to ligand charge-transfer transition（MLCT）.In addition,1displayed high Cu（II）/Cu（I）potential with E1/2=0.49V（vs SCE）as well.
