  X-ray analysis of phthalocyanines formed in the reaction of AuCu and AuSn alloys with 1,2-dicyanobenzene

  摘要：

  X-ray investigations of the reactions of copper, tin and their alloys with gold, with 1,2-dicyanobenzene at 210-degrees-C have been performed. It was found that under the conditions used, gold does not take part in the reaction with 1,2-dicyanobenzene, but separates from the alloys. Copper and tin phthalocyanines are formed as the main products of the above reactions. The crystal structure of tin phthalocyanine (SnPC) has been determined. SnPc crystallizes in the triclinic system (a = 12.048(3) angstrom, b = 12.630(3) angstrom, c = 8.671(3) angstrom, alpha = 95.85(5)-degrees, beta = 95.10(5)-degrees, gamma = 68.25(5)-degrees), space group P1BAR, Z = 2. The refined structure with anisotropic temperature factors gave R = 0.041. The Sn atom is coordinated by four isoindole N atoms, the average Sn-N distance being 2.267(6) angstrom. The SnPc molecule is not planar. The Sn atom is 1.1286 angstrom out of the plane of the four coordinating N atoms.

  Multistep Solution-Mediated Formation of AuCuSn₂:  Mechanistic Insights for the Guided Design of Intermetallic Solid-State Materials and Complex Multimetal Nanocrystals

  摘要：

  Understanding how solids form is a challenging task, and few strategies allow for the elucidation of reaction pathways that are useful for designing new solids. Here, we describe an unusual multistep reaction pathway that leads to the formation of AuCuSn2, a new ternary intermetallic compound that was discovered as nanocrystals using a low-temperature solution route. The formation of AuCuSn2 using a modified polyol process occurs through a multistep pathway that was elucidated by taking aliquots throughout the course of the reaction and studying the products using a variety of techniques. The reaction proceeds through four distinct steps: (a) formation of Au nanoparticles at or near room temperature, mediated by a galvanic reaction between Au3+ and Sn2+ (forming Au-0 and Sn4+, precipitated as SnO2 that forms a shell around the nanoparticles), (b) formation of NiAs-type AuSn nanoparticles, along with Cu and Sn, upon addition of NaBH4, (c) aggregation and thermal interdiffusion to form AuCuxSny alloy nanoparticles, and (d) nucleation of intermetallic AuCuSn2, which has an ordered NiAs-derived structure. The proposed mechanism was tested by starting the reaction with the AuSn intermediate. AuSn nanoparticles were synthesized separately and reacted with Cu and Sn nanoparticles, and ordered AuCuSn2 formed as expected. Elucidation of this reaction pathway has important implications for guiding the design of new intermetallic solids, as well as for controlling the synthesis of complex multimetal nanocrystals.

• Au₃SnP₇@Black Phosphorus:  An Easy Access to Black Phosphorus
  作者：Stefan Lange、Peer Schmidt、Tom Nilges

  DOI：10.1021/ic062192q

  日期：2007.5.1

  Black phosphorus can be prepared under low-pressure conditions at 873 K from red phosphorus via the addition of small quantities of gold, tin, and tin(IV) iodide. Au3SnP7, AuSn, and Sn4P3 were observed as additional phases. Tin(IV) iodide remains unreacted during the preparation process. The crystal structure of black phosphorus was redetermined from single crystals. P (295 K): a = 3.316(1) angstrom, b = 10.484(2) angstrom, c = 4.379(1) angstrom, V = 152.24(6) A(3), space group Cmce (No. 64). Solid-state P-31 MAS NMR spectroscopy and X-ray powder diffraction were performed to substantiate the high crystal quality of black phosphorus. A possible mechanism for the formation is discussed in terms of the comparable structural features of black phosphorus and Au3SnP7. Thermodynamic calculations showed that the only relevant gas-phase species, P-4, and the transport reactions are not suitable for the preparation of orthorhombic black phosphorus at temperatures above 773 K. A kinetically controlled mechanism must be favored instead of a thermodynamically controlled formation. The new preparation method of black phosphorus represents an easy and effective way to avoid complicated preparative setups, toxic catalysts, or "dirty" flux methods and is of general interest in elemental chemistry.

• Microstructural evolution and orientation-correlated origin of the coarsening behaviors in Au–Sn eutectic alloys

  Au-Sn eutectic alloys are widely used in lead-free sealings and solders. Hot rolling, a process of the combination of deformation and heat, remains an attractive method to thin the solder strips for bulk ingots of Au-Sn eutectic alloys, but the mechanisms governing the hot rolling process of Au-Sn eutectic alloys is not yet clear. Solder strips thinning is thus not reached easily. In this study, the heat induced coarsening origin and spheroidization mechanisms in Au-Sn eutectic alloys were uncovered in terms of the microstructural evolution and orientation relationship. Microstructure evolution of lamellar colony of Au-Sn eutectic alloy revealed that the initiation sites of coarsening occurs at the boundary of the lamellar colony structure and the end of the lamellar fault inside the colony structure. Termination migration was found to dominate the origin of coarsening mechanism of Au-Sn eutectic alloy, with involving large scale nano-lamellae, paired lamellar faults and a large number of coarsening structure. And another new coarsening mechanism, lamellae splitting, was proposed based on "groove" morphology, interface structure and crystallographic orientation relationship, to create massive lamellar faults for termination migration. The mechanisms will provide a new insight into coarsening origin. And the results pave the way of hot rolling Au-Sn eutectic alloys in terms of parameter selection, microstructure evolution and coarsening mechanisms. (C) 2019 Elsevier B.V. All rights reserved.
