Development of new Complex Compounds via Solid State Metathesis Reactions

热不稳定固体可以被认为是目前缺失或未知的化合物的最大组。在这个项目的框架内，我们试图制备和鉴定这类新化合物，这可能被认为是配位化学和固态化学之间的差距。实验将偏离固态复分解（SSM）反应，该反应已成功地应用于制备含有阴离子如L =（BN 2）3-、（CN 2）-或（OCN）-（或其三聚体（O3 C3 N3）3-形式）的固态化合物。具有这些阴离子的化合物在几种具有阳离子的环境中建立，对于具有正电性阳离子A的组合物A-M-L，M是主族或过渡金属。其中，我们将开发与（CH_3 NH_3）PbI_3密切相关的含卤化物（X）的A-M-X化合物，以及X = Cl、Br、I、N、S、Se或Te的衍生物A-M-X-L体系。在这些系统中的化合物是可获得的SSM反应从MX和AL化合物在温和的反应条件下，控制和分析的热分析测量（DTA，DSC）。新的固态配位化合物将被制备，结构表征，并研究性能（如光致发光）。

Thermally labile solids can be considered as the largest group of currently missing or unknown compounds. Within the framework of this project, we attempt to prepare and to identify new compounds of this category, which may be considered in the gap between coordination chemistry and solid-state chemistry. Experiments will depart from solid state metathesis (SSM) reactions that have been successfully applied to prepare solid state compounds containing anions such as L = (BN2)3-, (CN2)- or (OCN)- (or its trimeric (O3C3N3)3- form). Compounds with these anions are establsihed with several environments with cations, for compositions A-M-L with an electropositive cation A, and M being a main group or transition metal. Among them we will develop halide (X) containing A-M-X compounds closely related to (CH3NH3)PbI3, and derivative A-M-X-L systems in which X = Cl, Br, I, N, S, Se, or Te. Compounds in these systems are accessible by SSM reactions from MX and AL compounds under moderate reaction conditions, controlled and analysed by thermoanalytical measurements (DTA, DSC). The new solid-state coordination compounds will be prepared, structurally characterized, and investigated for properties (e.g. photoluminescence).
