    6-diaminopyridine ligands (PMN5) were synthesized and their 1D copper(II) complexes studied. When pyrazine is a terminal ring, the ligands showed in-plane and out-of-plane coordination modes and led to a one-dimensional zigzag chain polymer. The orthogonal overlap of orbitals through a bridging pyrazine ring resulted in ferromagnetic interaction. Middle-ring pyrazine-modulated ligands resulted in straight

  • Synthesis, structures and photoluminescence properties of silver(i) complexes with N,N′-di(pyrazin-2-yl)pyridine-2,6-diamine

    Four silver complexes with N,N′-di(pyrazin-2-yl)pyridine-2,6-diamine (H2dpzpda) as ligand, [Ag2(H2dpzpda)2](ClO4)2 (1), [Ag2(H2dpzpda)2(ClO4)2] (DMF)2 (2), [Ag2(H2dpzpda)2](CF3SO3)2 (3), and [Ag2(H2dpzpda)(DMF)4](PF6)2·DMF (4) have been synthesized and structurally characterized by elemental analyses, IR spectroscopy and single-crystal X-ray diffractometer methods. The single-crystal X-ray determination revealed that the molecular structures 1 and 3 are all cationic bimetallic supramolecular rectangles, [Ag2(H2dpzpda)2]2+, in which two H2dpzpda ligands adopt bis-monodentate bridging mode connecting two linearly coordinated silver(I) ions. For 2, adjacent rectangles are then mutually linked via the Ag⋯Ag interaction to form an infinite 1D chain. The structure of complex 4 can be best described as a 1D ladder-like infinite chain, which is constructed via two crystallographically independent Ag(I) ions connected by the H2dpzpda ligand with a tetra-monodentate bridging mode. The emission of 1 and 3 is ascribed to a intra-ligand-based π*–π transition, while the emission origin of 4 is likely arising from inter-ligand charge-transfer transition. The emission of complex 2 is attributed to a inter-ligand charge-transfer transition. Moreover, two-photon excitation emission (TPEF) and two-photon absorption cross section of complex 2 were measured from TPEF via confocal microscope and Z-scan methods, for which two-photon cross section in solid state was deduced to be 43.4 ± 2.2 GM (800 nm).
    以 N,Nâ²-二(吡嗪-2-基)吡啶-2,6-二胺(H2dpzpda)为配体的四种配合物[Ag2(H2dpzpda)2](ClO4)2 (1)、[Ag2(H2dpzpda)2( )2] (DMF)2 (2)、[Ag2(H2dpzpda)2](CF3SO3)2 (3)、合成了[Ag2(H2dpzpda)(DMF)4](PF6)2Â-DMF (4),并通过元素分析、红外光谱和单晶 X 射线衍射仪方法对其结构进行了表征。单晶 X 射线测定显示,分子结构 1 和 3 都是阳离子双属超分子矩形 [Ag2(H2dpzpda)2]2+,其中两个 H2dpzpda 配体采用双单齿桥接模式连接两个线性配位的(I)离子。对于 2,相邻的矩形通过 Agâ¯Ag 相互作用相互连接,形成一个无限的一维链。复合物 4 的结构可以最好地描述为一条一维阶梯状无限链,它是由两个晶体学上独立的 Ag(I) 离子通过 H2dpzpda 配体以四单齿桥接模式连接而成。复合物 1 和 3 的发射归因于配体内的Ï*âÏ 转变,而复合物 4 的发射则可能来自配体间的电荷转移转变。复合物 2 的发射则归因于配体间的电荷转移转变。此外,通过共聚焦显微镜和 Z 扫描方法测量了复合物 2 的双光子激发发射(TPEF)和双光子吸收截面。

    New pentachromoium metal string complexes [Cr5(μ5-L)4X2] (X = Cl−, L = dppzda2− (1), dpzpda2− (2); X = NCS−, L = dppzda2− (3), dpzpda2− (4)) were designed and synthesized through pyrazine-modulation of tripyridyldiamine ligand. X-Ray crystallographic studies revealed a linear metal chain structure consisting of two quadruple Cr–Cr bonds and a separated high spin Cr(II) at an end in crystallized form. A quintet ground state was observed for all pentachromium(II) molecules by magnetic study with g values of 2.04–2.18. While the electronic structure remained unchanged after the modification of ligands, electrochemistry showed a significant change in the molecular orbital energy levels of metal string molecules. Observation of the first oxidation peak of 1 at +0.57 V and of 2 at +0.73 V revealed that these complexes are quite resistant to oxidation. Single molecular conductance measurements showed that the complex exhibited good electronic conductance.

    Pentacobalt EMACs [Co5(μ5-dpzpda)4X2] (X = Cl− (1), NCS− (2)) with fine-tuning of the supporting ligand based on the tripyridyldiamine ligand, N,N′-di(pyrazin-2-yl)pyridine-2,6-diamine (H2dpzpda), and their reduced form (Ph4P)[Co5(μ5-dpzpda)4X2] (X = Cl− (3), NCS− (4)) were first synthesized and structurally characterized. The structures of 1–4 showed direct Co–Co bonds with Co–Co distances in the range 2.2385(7)–2.2888(15) Å, and valence electrons delocalized through the whole metal chain with distances of longer than 9.06 Å. The distances of the inner Co–Co bonds and the Co–axial ligands became longer after reduction, whereas no significant change was observed in the distances of the outer Co–Co bonds and Co–N (supporting ligand) bonds, which was consistent with the MO analysis. Electrochemical studies on both 1 and 2 showed one reversible oxidation and one reversible reduction at E1/2 = +0.82 and −0.05 V for 1, and at E1/2 = +0.89 and +0.02 V for 2, respectively. The redox reactions of the thiocyanate complex 4 happened at higher potentials than the chloride complex 3. A magnetism study of 1–4 revealed anomalous magnetic behaviour similar to that of heptacobalt EMACs, and a deviation from the Curie–Weiss law was observed. The χMT value at 300 K is 0.84 and 1.16 emu K mol−1 for 1 and 2, respectively, suggesting spin-equilibrium or a spin-admixture between doublet and quartet states arising from the Boltzmann distribution over different energy levels. Similar results were obtained for 3 and 4, showing intermediate χMT values between a diamagnetic and a triplet state of 0.15–0.96 emu K mol−1 in the temperature range 5–300 K. The structural and magnetic results were interpreted through an EHMO study.
    EMAC [Co5(μ5-dpzpda)4X2] (X = Cl-(1), NCS-(2)),并基于三吡啶二胺配体 N,N-di(吡嗪-2-基)吡啶-2,6-二胺 (H2dpzpda) 及其还原形式 (Ph4P)[Co5(μ5-dpzpda)4X2] (X = Cl– (3), NCS– (4))首先进行了合成并进行了结构表征。 1–4 的结构显示出直接的 Co–Co 键,Co–Co 距离在 2.2385(7)–2.2888(15) – 范围内,价电子在整个属链中离域,距离大于9.06 ×。还原后,内部Co-Co键和Co-轴配体的距离变长,而外部Co-Co键和Co-N(支持配体)键的距离没有观察到显着变化,这与 MO 分析一致。对 1 和 2 的电化学研究表明,1 的 E1/2 = +0.82 和 ±0.05 V 时有一种可逆氧化,2 的 E1/2 = +0.89 和 +0.02 V 时有一种可逆还原。硫氰酸盐配合物 4 的氧化还原反应发生在比化物配合物 3 更高的电势下。1–4 的磁性研究揭示了与七 EMAC 类似的异常磁性行为,并观察到与居里-韦斯定律的偏差。 1 和 2 在 300 K 时的 MT 值分别为 0.84 和 1.16 emu K MOl-1,这表明在不同能级上的玻尔兹曼分布产生的双重态和四重态之间的自旋平衡或自旋混合。 3 和 4 也获得了类似的结果,显示在 5–300 K 的温度范围内,抗磁性和三重态之间的中间 δMT 值为 0.15–0.96 emu K MOl–1。结构和磁性结果为通过 EHMO 研究进行解释。

Two terminal Ni(II) ions bonded to the axial ligands are in a square-pyramidal (NiN 4 Cl) environment and exhibit long Ni N bonds (2.097(4) A), which are consistent with a high-spin Ni(II) configuration.

    摘要通过使用三吡啶基二胺配体N,N'-二(吡嗪-2-基)吡啶-2,6-二胺(H 2 dpzpda),线性五核(II)[Ni 5(µ 5 -dpzpda)4 Cl 2 ](1)和四核(II)[Cu 4(Hdpzpda)2(CH 3 COO)6](2)配合物首先被合成并进行结构表征。该五氧化线性属链被四个syn-syn-syn-syn型dpzpda 2-配体螺旋缠绕。复合体中存在两种类型的Ni Ni距离。受轴向配体影响的末端Ni Ni距离更长(2.3877(8)A)。内部Ni Ni距离非常短,并且保持恒定(2.3071(6)A)。与轴向配体键合的两个末端Ni(II)离子处于方形锥体(NiN 4 Cl)环境中,并显示出长的Ni N键(2.097(4)A),与高旋转Ni(II)一致配置。内部的三个Ni(II)离子显示出短的Ni N(1.8915(8)–1.903(4)A)键距,这与方形平面(NiN
