| Cu(Ⅰ)Fe(Ⅱ) Heterobimetallic Complexes Based on Functionalized 6-Methoxycarbonyl-2,2'-bipyridine Ligands | |
| 摘要: 以[Cu（CH3CN）4]ClO4、6-甲氧羰基-2，2'-联吡啶（mbpy）、6-甲氧羰基-4，4'-二甲基-2，2'-联吡啶（mmbpy）和1，1'-双（二苯基膦）二茂铁（dppf）为起始原料，合成得到了2个新的铜（Ⅰ）铁（Ⅱ）异金属双核配合物：[Cu（mbpy）（dppf）]ClO4·CH2Cl2（1）和[Cu（mmbpy）（dppf）]ClO4（2）。X射线单晶衍射分析表明，配合物1和2均为铜（Ⅰ）铁（Ⅱ）异金属双核配合物，并且均表现为四配位变形四面体构型。配合物1和2在330~520 nm波长范围有一个弱的低能量宽吸收峰，其主要来源于金属到配体的电荷转移跃迁（MLCT）。由于1，1'-双（二苯基膦）二茂铁的引入，配合物1和2常温下在溶液和固态时均未检测到任何发光。 | |

| Abstract: Two new Cu(Ⅰ)Fe(Ⅱ) heterobimetallic complexes,[Cu(mbpy)(dppf)]ClO4·CH2Cl2 (1) and[Cu(mmbpy)(dppf)]ClO4 (2), were synthesized by using[Cu(CH3CN)4]ClO4, 6-methoxycarbonyl-2,2'-bipyridine (mbpy), 6-metho-xycarbonyl-4,4'-dimethyl-2,2'-bipyridine (mmbpy), and 1,1'-bis(diphenylphosphino)ferrocene (dppf) as the starting materials. As revealed by single-crystal X-ray diffraction analysis, complexes 1 and 2 are all Cu(Ⅰ)Fe(Ⅱ) heterobimetallic species and exhibit tetra-coordinated and distorted tetrahedral configuration. Complexes 1 and 2 all show a weak low-energy broad absorption in the wavelength range of 330~520 nm, which is mainly assigned to metal-to-ligand charge-transfer (MLCT) transition. No emission is detected in solution and solid states at room temperature for 1 and 2, due to the introduction of 1,1'-bis(diphenylphosphino)ferrocene. | |
