9803088EchegoyenThis research program aims to synthesize a series of organometallic complexes consisting of ruthenium II, iron II, or osmium II coordinated to bipyridine-like ligands that exhibit unusual geometries and architectures. The compounds will be characterized using a combination of electrochemistry and electron spin resonance (ESR) to determine properties such as electrocrystallization and the degree of electronic coupling between metallic centers, between theligand structures, as well as intramolecular charge and spin delocalization. Novel solid-state materials will then be prepared from these compounds by electrocrystallization techniques to generate sisngle crystalline materials of sufficient quality to be analyzed using techniques such as x-ray diffraction, optical spectroscopy, power, and thermal conductivity as a function of temperature and magnetic field. The aim is to obtain a unique class of novel molecular materials with unusual and possibly technologically useful transport properties.%%%This interesting class of compounds is being explored as a source of highly unusual and very interesting materials exhibiting novel electronic, magnetic and optical properties. These investigations may lead to the use of electrides as solid-state electronic or magnetic materials for devices.***

9803088这个研究项目旨在合成一系列由Ru II、Fe II或Om II与联吡啶类配体配位的有机金属配合物，这些配体显示出不寻常的几何和结构。这些化合物将使用电化学和电子自旋共振(ESR)相结合的方法进行表征，以确定诸如电结晶和金属中心之间、配体和结构之间的电子耦合程度以及分子内电荷和自旋离域等性质。然后，将通过电结晶技术从这些化合物中制备新型固态材料，以生成足够质量的单晶材料，以便使用诸如X射线衍射、光学光谱、功率和热导率随温度和磁场的函数等技术进行分析。其目的是获得一类独特的新型分子材料，具有不寻常的和可能在技术上有用的传输性质。%这类有趣的化合物正在被探索为一种非常不寻常和非常有趣的材料的来源，显示出新的电子、磁性和光学性质。这些研究可能导致将电子材料用作设备的固态电子或磁性材料。
