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.

描述：该项目是为了支持俄克拉荷马州州立大学化学系的Elizabeth Holt博士和Dr.A. Boukhari，摩洛哥拉巴特，穆罕默德五世大学，拉巴特科学学院固体化学系。 该研究将重点关注AIBIIP2O7复合物结构的改变，目的是生产具有商业性质的新材料。 这类化合物的许多物理性质都是由B原子的行为引起的。 因此，将探索改变B原子环境的各种方法。 包括：MIMIIP_2O_7型铁磁二磷酸盐配合物的制备，AlIBIIP_2O_7中两个Al原子取代单个Al原子，以及混合价态材料（BIIBIII）P_2O_7的探索。 预计这些类型的变化将导致系统具有增加的金属与金属的相互作用，从而具有有趣的物理性质。 范围：该项目将资助两名摩洛哥硕士的访问。和博士学生从穆罕默德五世大学到俄克拉荷马州州立大学的晶体学实验室。，每年开展材料结构研究。它还支持两名高级科学家相互访问对方的实验室。 该项目允许在样品制备和分析研究方面具有经验的摩洛哥小组与在实验化学，特别是晶体学方面具有相当经验的美国科学家合作。 大部分合成工作将在拥有世界上最大磷矿的摩洛哥完成，而结构表征将在霍尔特博士的实验室在她的监督下完成。 Holt博士最近与Boukhari博士进行了非常成功的合作，并发表了几篇论文。 该项目将以这种关系为基础，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项目部的目标。
