摘　　要：以[Cu(CH_3CN)_4]ClO_4、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)]ClO_4·CH_2Cl_2(1)和[Cu(mmbpy)(dppf)]ClO_4(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。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.CCDC:1835415,1;1835416,2.
