  mol cmAg2S 22 s 21 . When cyanidation was performed on a sulfide concentrate~1.4% acanthite!, a normalized reaction velocity, several orders of magnitude lower, was obtained, even after compensating for the effects of diffusion. An analysis of the reactions involved, both in the electrochemical and the leaching systems, showed a notable difference between the two, reflected by dissimilar interfacial

  摩尔 cmAg2S 22 s 21 . 当对硫化物精矿约 1.4% 的针叶石进行氰化时，即使在补偿扩散效应之后，也获得了低几个数量级的归一化反应速度。对电化学和浸出系统中所涉及反应的分析表明，两者之间存在显着差异，这反映在不同的界面氢氧根离子浓度上。化学气氛的这种差异对使用埃文斯图来描述某些系统中的浸出动力学的有效性提出了质疑。此外，这项研究还确定，对于这两种系统，水相铅离子加速了硫化银氧化，因为它们充当氢氧根和/或硫化物离子的螯合剂。

  Neutral transition metal complexes of different α,ω-dimethyltripyrrins TrpyMX with M = CuII and ZnII have been prepared with a variety of anionic halogeno and pseudohalogeno ligands X, and have been studied with respect to coordination modes and structural distortion. Only four- and five-coordinate species have been observed throughout the series. All four-coordinate species display unstrained, but distorted tetrahedral or strained and distorted square-planar coordination environments for zinc(II) and copper(II) species, respectively, thus following the expectations from simple ligand field arguments. Five-coordinate species do not form easily and were observed either in donor solvents or in the solid as 1D coordination polymers with distorted trigonal-bipyramidal coordination and different topologies.

  我们用各种阴离子卤代和假卤代配体 X 制备了不同的 α,ω-二甲基三吡喃 TrpyMX 的中性过渡金属配合物，并就配位模式和结构畸变进行了研究。在整个系列中只观察到四配位和五配位物种。对于锌（II）和铜（II）来说，所有四配位物种都分别显示出未受约束但扭曲的四面体配位环境或受约束但扭曲的方平面配位环境，因此符合简单配体场论证的预期。五配位物种不易形成，在供体溶剂中或在固体中观察到的五配位物种都是一维配位聚合物，具有扭曲的三叉双锥配位和不同的拓扑结构。

  Raman spectra of cyano-complexes of silver(I) in liquid ammonia solution have been interpreted to show the existence, in equilibrium, of the following species: AgCN, AgNC, [Ag(CN)2]–, [Ag(CN)(NC)]–, [Ag(NC)2]–, [Ag(CN)3]2–, [Ag2(CN)]+, [Ag2(CN)2], [Ag2(CN)3]–, [MAg2(CN)5]2–(M = Na+ or K+), and [MAg(CN)3]–(M = Li+, Na+, or K+). The factors affecting the linkage isomerism, ion aggregation, ion pairing

• Calorimetric study of molecular superconductor κ-(BEDT-TTF)2Ag(CN)2H2O which contains water in the anion layers

  Thermodynamic investigation of an organic superconductor κ-(BEDT-TTF)2Ag(CN)2H2O in which the BEDT-TTF dimers are arranged in the κ-type structure in the donor layers is performed by the relaxation calorimetric technique at low temperatures and under magnetic fields. A thermal anomaly related to the superconductive phase transition was observed at 5 K. The existence of residual γ* in the superconductive state is about 18% of the normal state γ value, which is larger than those of κ-(BEDT-TTF)2Cu(NCS)2, and κ-(BEDT-TTF)2Cu[N(CN)2]Br salt. The lattice heat capacity reflected on the β-term in the low-temperature heat capacity was found to be affected by the cooling rate. The disorder produced in the network structure constructed by hydrogen bond in the insulating layer is considered to give low-energy phonon excitations reflected in the heat capacity.

  在低温和磁场条件下，通过弛豫量热技术对有机超导体 κ-(BEDT-TTF)2Ag(CN)2H2O进行了热力学研究。超导态存在的残余γ*约为正常态γ值的18%，大于κ-(BEDT-TTF)2Cu(NCS)2和κ-(BEDT-TTF)2Cu[N(CN)2]Br盐。低温热容中β项所反映的晶格热容受冷却速率的影响。在绝缘层中通过氢键构建的网络结构中产生的无序被认为会产生反映在热容量中的低能声子激发。

  A series of gold- and silver-containing ionic liquids, [CnMIM][M(CN)2] (M = Au, Ag; n = 12, 14, 18), prepared by metathesis reactions, present luminescence depending on their physical state i.e. crystalline or smectic A phases. The photoluminescent measurements as well as DFT calculations suggest that the modulation of aurophilic intermolecular interactions are responsible for this phosphorescent behaviour.

  通过复分解反应制备的一系列含金和银的离子液体，[CnMIM][M(CN)2] (M = Au, Ag; n = 12, 14, 18)，根据其物理状态呈现发光即结晶相或近晶A相。光致发光测量以及 DFT 计算表明，亲金分子间相互作用的调节是造成这种磷光行为的原因。
