项目摘要

The chemistry and physics of Zintl phases and Zintl anions has been enhanced during the past 20 years by addition of novel aspects that led this traditional area of inorganic synthesis and structural chemistry into a highly topical field, addressing chemical, physical as well as material sciences issues. Within our project DE-758/12-1, we worked on Multinary Zintl-Phases comprising Elements of Groups 13-15 and Ternary Molecular Intermetalloids. Based on the great success of the project, which afforded 9 publications so far in highly reputable journals, we intend to further develop our research on binary Zintl anions and ternary intermetalloid clusters. We are planning to follow different pathways that allow for both, continuation and extension of the previous work with novel elemental combinations on the one hand and investigations on novel synthesis routes and target compounds that have so far not been studied. The project outline is dedicated to two major goals: A) Synthesis, thorough characterization and formation studies of compounds comprising ternary molecular intermetalloids according to the general formula [MxE1yE2z]q- (M = transition metal, lanthanoid, U; E1 = group 13 or 14 element; E2 = group 14 or 15 element; E1 not equal to E2). To achieve the objectives, we will make use of the variety of different elemental combinations at first place. Secondly, we will test further synthetic strategies to broaden the product spectrum as well as to get the chance of gaining new insight into formation processes in order to understand and even better control them. B) Derivatization of binary Zintl anions and ternary intermetalloid clusters with organic or organo-element ligands R, thereby utilizing the the heteropolarity of binary and ternary systems, and decomposition of binary and ternary Zintl anions according to the general formula [RnMxE1yE2z]q- (n,x larger than/equal to 0) to form novel intermetallic phases. Chemical and physical properties of all products will be subject to detailed studies using all experimental equipment available; besides determination of the identity of the samples, this should serve to elucidate formation pathways, stabilities and reactivities of compounds with binary or ternary intermetalloid Zintl anions - crucial issues for significant further development of the field. For clarification of open questions that cannot be addressed by using experimental techniques, quantum chemical investigations will represent an essential part of the project. This specific combination of high-sophisticated synthesis and multifaceted analyses has been very fruitful in the past and shall contribute to future success of the planned investigations.

在过去的20年中，Zintl阶段和Zintl阴离子的化学和物理学通过添加了新的方面，从而提高了这一传统的无机合成和结构化学领域的新方面，从而解决了高度局部的领域，从而解决了化学，物理和物质科学问题。在我们的项目de-758/12-1中，我们研究了组成13-15组和三元分子间层元素元素的多元Zintl-责任。基于该项目的巨大成功，该项目迄今为止在备受瞩目的期刊上提供了9份出版物，我们打算进一步发展我们对二元Zintl阴离子和三元金属层间簇的研究。我们计划遵循不同的途径，这些途径允许一方面与新的元素组合以及对新型合成途径和靶向化合物进行研究，以延续和扩展以前的作品，这些途径尚未研究。该项目大纲旨在实现两个主要目标：a）根据一般式[MXE1YE2Z] Q-（M =过渡金属，lanthanoid，u; e1 = 13或14元素；为了实现目标，我们将首先利用各种不同的元素组合。其次，我们将测试进一步的合成策略，以扩大产品光谱，并有机会获得对编队过程的新见解，以便理解甚至更好地控制它们。 b）二元Zintl阴离子和三元间的衍生物与有机或有机元的配体R r r，从而利用二元和三元系统的异质性，以及根据一般公式[rnmxe1ye2z] Q-nefore for Nepenter for Heporter for Hepornal for for Norment for Shorm Iteral for by for Shorm Iterals for Shorm Iteral for Shorm for Shorm for Shorm for Shorm for Shorm for Shorm for Shorm for Shorm for Shorm for Shorm for Shorm for Shorm for Shorm for Shorm ftel-Neptral in kat y/n istall zintl zintl。所有产品的化学和物理特性将使用所有可用的实验设备进行详细研究；除了确定样品的身份外，这还应用于阐明具有二元或三元间胶体间Zintl阴离子的化合物的稳定性，稳定性和反应性 - 至关重要的问题，以实现该领域的重大进一步发展。为了阐明无法通过使用实验技术解决的开放问题，量子化学研究将代表项目的重要组成部分。过去，高认识的合成和多方面分析的这种特殊组合在过去一直非常富有成果，并应为计划研究的未来成功做出贡献。
