This award in the Inorganic, Bioinorganic, and Organometallic Chemistry Program continues support for research on the synthesis of complex metal oxides by Dr. Jon Zubieta of the Chemistry Department, Syracuse University. Organic ligands introduced during hydrothermal preparations to form unusual solids of three general types: microporous solids with zeolite scale cavities; two dimensional networks linked by organic tethers, and V/O or Mo/O inorganic skeletons incorporating secondary coordination complexes. These open-framework and layered structures will be prepared by low-temperature methods that will permit the isolation of kinetically stable phases. The long-term goal of this research is the 'design' of one, two, and three dimensional coordination complexes that will provide a scaffold to entrain oxide substructures. Metal oxide based solid phase compounds are important in catalysis, sorption, molecular electronics, energy storage, optical materials, and ceramics. Variations in chemical composition and structure effect a wide range of properties. New synthetic approaches to introducing organic groups are expected to result in compounds with an expanded range of properties by compensating charge, directing structural growth, or connecting functional groups.

无机，生物无机和有机化学计划的这一奖项继续支持锡拉丘兹大学化学系的Jon Zubieta博士对复杂金属氧化物合成的研究。在水热制备过程中引入的有机配体形成三种一般类型的不寻常的固体：具有沸石规模空腔的微孔固体;由有机系链连接的二维网络，以及包含次级配位络合物的V/O或Mo/O无机骨架。这些开放式框架和层状结构将通过低温方法制备，这将允许分离动力学稳定相。这项研究的长期目标是“设计”一维，二维和三维的配位复合物，这将提供一个支架夹带氧化物亚结构。基于金属氧化物的固相化合物在催化、吸附、分子电子学、能量存储、光学材料和陶瓷中是重要的。化学成分和结构的变化影响着广泛的性能。引入有机基团的新合成方法有望通过补偿电荷、引导结构生长或连接官能团来产生具有扩展性质范围的化合物。
