Abstract

The electrochemistry and spectral properties of a series of mono- and binuclear complexes with bridging ligands based on 2,3-di(2-quinolyl)quinoxaline are reported. The ligands are 2,3-di(2-quinolyl)quinoxaline (dqq), 6,7-dimethyl-2,3-di(2-quinolyl)quinoxaline (dqqMe(2)), and 6,7-dichloro-2,3-di(2-quinolyl)quinoxaline (dqqCl(2)). The complexes are [Cu(dqq)(PPh(3))(2)]BF(4), 1.[BF(4)]; [Cu(dqqMe(2))(PPh(3))(2)]BF(4), 2.[BF(4)]; [Cu(dqqCl(2))(PPh(3))(2)]BF(4), 3.[BF(4)]; (PPh(3))(2)Cu(dqq)Cu(PPh(3))(2)(2), 4.BF(4); (PPh(3))(2)Cu(dqqMe(2))Cu(PPh(3))(2)(2), 5.BF(4); (PPh(3))(2)Cu(dqqCl(2))Cu(PPh(3))(2)(2), 6.BF(4). The mononuclear complexes reduce at the metal and dechelate, as evidenced by UV/vis spectroelectrochemistry. Reduction of the binuclear complexes results in ligand-based radical anion formation for 4 and 6 but decomposition of 5 to 2. The reduction species are identified using resonance Raman spectroscopy. The structures of [Cu(PPh(3))(2)(C(26)H(14)Cl(2)N(4))][BF(4)] (3.[BF(4)]) and [(Cu(PPh(3))(2))(2)(C(26)H(14)Cl(2)N(4))]BF(4).2CH(2)Cl(2) (6.BF(4)) were determined by single-crystal X-ray diffraction. 3.[BF(4)] crystallized in the monoclinic space group P&onemacr; with cell dimensions a = 10.956(2) Å, b = 15.278(3) Å, c = 16.032(3) Å, alpha = 100.342(8) degrees, beta = 95.291(13) degrees, gamma = 93.968(12) degrees, Z = 2, rho(calcd) = 1.431 g/cm(3), and R(F(o)) = 0.0589. 6.BF(4) crystallized in the monoclinic space group C2/c with cell dimensions a = 21.295(4) Å, b = 24.322(5) Å, c = 20.034(4) Å, beta = 112.64(3) degrees, Z = 8, rho(calcd) = 1.486 g/cm(3), and R(F(o)) = 0.0422.

摘要

报道了一系列基于2,3 - 二(2 - 喹啉基)喹喔啉并带有桥连配体的单核和双核配合物的电化学和光谱性质。这些配体为2,3 - 二(2 - 喹啉基)喹喔啉(dqq)、6,7 - 二甲基 - 2,3 - 二(2 - 喹啉基)喹喔啉(dqqMe(2))以及6,7 - 二氯 - 2,3 - 二(2 - 喹啉基)喹喔啉(dqqCl(2))。配合物分别为[Cu(dqq)(PPh(3))(2)]BF(4)，即1.[BF(4)]；[Cu(dqqMe(2))(PPh(3))(2)]BF(4)，即2.[BF(4)]；[Cu(dqqCl(2))(PPh(3))(2)]BF(4)，即3.[BF(4)]；(PPh(3))(2)Cu(dqq)Cu(PPh(3))(2)(2)，即4.BF(4)；(PPh(3))(2)Cu(dqqMe(2))Cu(PPh(3))(2)(2)，即5.BF(4)；(PPh(3))(2)Cu(dqqCl(2))Cu(PPh(3))(2)(2)，即6.BF(4)。紫外/可见光谱电化学表明，单核配合物在金属处发生还原并脱螯合。双核配合物4和6的还原导致基于配体的自由基阴离子形成，而5则分解为2。利用共振拉曼光谱对还原产物进行了鉴定。通过单晶X射线衍射测定了[Cu(PPh(3))(2)(C(26)H(14)Cl(2)N(4))][BF(4)]（3.[BF(4)]）和[(Cu(PPh(3))(2))(2)(C(26)H(14)Cl(2)N(4))]BF(4).2CH(2)Cl(2)（6.BF(4)）的结构。3.[BF(4)]结晶于单斜空间群P&onemacr;，晶胞参数a = 10.956(2) Å，b = 15.278(3) Å，c = 16.032(3) Å，α = 100.342(8)°，β = 95.291(13)°，γ = 93.968(12)°，Z = 2，ρ(calcd) = 1.431 g/cm(3)，R(F(o)) = 0.0589。6.BF(4)结晶于单斜空间群C2/c，晶胞参数a = 21.295(4) Å，b = 24.322(5) Å，c = 20.034(4) Å，β = 112.64(3)°，Z = 8，ρ(calcd) = 1.486 g/cm(3)，R(F(o)) = 0.0422。
