| 摘要: 以6-甲氧羰基-2，2’-联吡啶（mbpy）为氮杂环二齿螯合配体，1，2-双（二苯基膦）乙烷（dppe）和1，3-双（二苯基膦）丙烷（dppp）为辅助配体，合成了2个单核铜（Ⅰ）配合物[Cu（mbpy）（dppe）]ClO4（1）和[Cu（mbpy）（dppp）]ClO4·CH2Cl2（2），并应用元素分析、红外光谱、紫外可见吸收光谱和X射线单晶衍射进行了表征。晶体结构分析表明，配合物1和2均为单核铜（Ⅰ）配合物，中心铜（Ⅰ）离子与联吡啶环的2个氮原子和双膦配体的2个磷原子相连接而构成一个扭曲变形的四面体几何构型。配合物1和2在350~525 nm范围有一个弱的低能量吸收带，归属为具有明显的金属到配体电荷转移（MLCT）特性的电荷转移跃迁。 | |

| Abstract: Two mononuclear Cu(Ⅰ) complexes,[Cu(mbpy)(dppe)]ClO4 (1) and[Cu(mbpy)(dppp)]ClO4·CH2Cl2 (2), have been synthesized by using 6-methoxycarbonyl-2,2'-bipyridine (mbpy) as N-heterocyclic bidentate chelating ligand and 1,2-bis(diphenylphosphino)ethane (dppe) and 1,3-bis(diphenylphosphino)propane (dppp) as auxiliary ligand. They have been well characterized by elemental analysis, infrared spectroscopy, UV-Vis absorption spectroscopy and single-crystal X-ray diffraction. As revealed by crystal structure analysis, complexes 1 and 2 are all mononuclear Cu(Ⅰ) complexes and the central Cu(Ⅰ) ion coordinates with two N atoms of the 2,2-bipyridyl ring and two P atoms of bisphosphine ligand to generate a distorted tetrahedral configuration. Complexes 1 and 2 have a weak low-energy absorption band in the 350~525 nm region, assigned to charge-transfer transitions with appreciable metal-to-ligand charge-transfer (MLCT) character.
