Structural Studies of Inorganic Phosphates, US-Morocco Cooperative Research

描述：这个项目是为了支持俄克拉荷马州立大学化学系伊丽莎白·霍尔特博士和摩洛哥拉巴特大学拉巴特科学学院的A.Boukhari博士的合作研究。这项研究将集中在改变AIBIIP2O7络合物的结构，以期生产出具有商业性质的新材料。这一家族的许多已知络合物的物理性质都源于B原子的行为。因此，将探索改变B原子环境的各种方法。包括：MIMIIP2O7铁磁性二磷酸盐络合物的制备，用两个Al原子取代AIIBIIP2O7中的一个AlII原子，以及探索混合价材料(BIIBIII)P2O7。这些类型的变化有望导致系统具有更多的金属对金属的相互作用，从而产生有趣的物理性质。项目范围：该项目旨在资助穆罕默德五世大学的两名摩洛哥硕士和博士生每年访问俄克拉荷马州立大学的晶体实验室，进行材料结构研究。它还支持两位资深科学家互访对方的实验室。该项目允许在样品制备和分析研究方面有经验的摩洛哥小组与在实验化学方面，特别是在结晶学方面有相当经验的美国科学家进行合作。大部分合成工作将在摩洛哥完成，摩洛哥拥有世界上最大的磷矿，而结构表征将在霍尔特博士的实验室在她的监督下完成。霍尔特博士最近与布哈里博士进行了一次非常成功的合作，并出版了几本书。该项目将建立在这种关系的基础上，并将通过吸收更多来自摩洛哥的学生来扩大合作。该项目非常符合国际方案司的目标。

Description: This project is to support collaborative research by Dr. Elizabeth Holt, Chemistry Department, Oklahoma State University, and Dr.A. Boukhari, Laboratoire de Chemie du Solide Appliquee, Faculte des Sciences de Rabat, Universite Mohammed V, in Rabat, Morocco. The research will focus on alteration of the structures of AIBIIP2O7 complexes with the aim of producing new materials with commercial properties. The physical properties of many known complexes of this family arise from the behavior of the B atom. Thus various methods of altering the environment of the B atom will be explored. Included are: the preparation of ferromagnetic diphosphate complexes of form MIMIIP2O7, substitution of two AI atoms for a single AII atom in AIIBIIP2O7 and exploration of mixed valence materials, (BIIBIII)P2O7. These types of changes are expected to lead to systems with increased metal to metal interaction, and thus interesting physical properties. Scope: This project is to fund visits by two Moroccan M.S. and Ph.D. students from the Universite Mohammed V to the crystallographic laboratories at Oklahoma State U. ,each year, to carry out materials structural research. It also supports visits by the two senior scientists to each other laboratories. The project allows the collaboration of the Moroccan group, with experience in sample preparation and analytical studies, with the US scientist who has considerable experience in experimental chemistry, especially in crystallography. The bulk of the synthetic work will be done in Morocco, a country with the largest phosphate mines in the world, while the structural characterization will be done at Dr. Holt's laboratory under her supervision. Dr. Holt has had a very successful collaboration recently with Dr. Boukhari which resulted in several publications. This project will build on this relationship, and will expand the collaboration by including additional students from Morocco. The project fits well with the objectives of the Division of International Programs.
