This award will support collaborative research between Dr. Jon Zubieta, State University of New York at Albany, and Dr. Yves Jeanin, Laboratorie de Chimie des Metaux de Transition, University of Pierre and Marie Curie Paris, France. The objective of the project is the investigation of coordination compounds of polyoxomolybdate anions. Since heterogeneous metal oxide surfaces play an increasingly important role in the chemical industry, the chemical processes which occur on these surfaces are of considerable interest. The chemistry of polyoxomolybdates with organonitrogen species is of particular importance in providing chemical models for abiological nitrogen fixation and industrial ammoxidation. In this joint project, the investigators will exploit currently developed synthetic methodologies for organohydrazido complexes of polyoxo- molybdates to the coordination chemistry of polymetalates with organoimido ligands. The experimental plan will concentrate on the synthesis of organoimido derivatives of organic soluble polyoxomo- lybdates, of polyoxomolybdate complexes stabilized by coligands, and of lacunary polyoxometalates. The complexes will be character- ized using X-ray crystallography, multinuclear NMR and electro- chemistry. Thermal and photochemical decomposition reactions of the organoimido derivatives, as well as their reactions with allyalcohol and alkenes will be investigated. The project will benefit from the complementary expertise of the US and French investigators; the two laboratories have been studying related aspects of the coordination chemistry of polyoxometalates with organonitrogen ligands for several years.

该奖项将支持纽约州立大学奥尔巴尼分校的 Jon Zubieta 博士和法国巴黎皮埃尔和玛丽居里大学化学转化实验室的 Yves Jeanin 博士之间的合作研究。 该项目的目标是研究多钼酸根阴离子的配位化合物。 由于异质金属氧化物表面在化学工业中发挥着越来越重要的作用，因此在这些表面上发生的化学过程引起了相当大的兴趣。 多钼酸盐与有机氮物质的化学对于提供非生物固氮和工业氨氧化的化学模型特别重要。 在这个联合项目中，研究人员将利用目前开发的多钼氧酸盐有机酰肼配合物的合成方法来进行多金属酸盐与有机酰亚胺配体的配位化学。 实验计划将集中于有机可溶性多钼氧酸盐的有机酰亚胺衍生物、共配体稳定的多钼酸盐配合物以及缺位多金属氧酸盐的合成。 这些配合物将使用 X 射线晶体学、多核核磁共振和电化学进行表征。 将研究有机亚氨基衍生物的热和光化学分解反应，以及它们与烯丙醇和烯烃的反应。 该项目将受益于美国和法国研究人员的互补专业知识；这两个实验室多年来一直在研究多金属氧酸盐与有机氮配体的配位化学的相关方面。
