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.

Zintl 相和 Zintl 阴离子的化学和物理在过去 20 年中通过添加新的方面得到了增强，这些新的方面使无机合成和结构化学这一传统领域成为一个高度热门的领域，解决化学、物理和材料科学问题。在我们的项目 DE-758/12-1 中，我们研究了包含第 13-15 族元素和三元分子间金属间化合物的多元 Zintl 相。基于该项目迄今为止在知名期刊上发表了 9 篇论文的巨大成功，我们打算进一步发展二元 Zintl 阴离子和三元金属间化合物团簇的研究。我们计划遵循不同的途径，一方面可以延续和扩展先前的工作，一方面采用新颖的元素组合，另一方面研究迄今为止尚未研究的新颖的合成路线和目标化合物。该项目大纲致力于实现两个主要目标：A) 根据通式 [MxE1yE2z]q-（M = 过渡金属、镧系元素、U；E1 = 第 13 族或14 元素；E2 = 14 或 15 族元素；E1 不等于 E2)。为了实现这些目标，我们首先将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，以拓宽产品范围，并有机会获得对形成过程的新见解，以便理解甚至更好地控制它们。 B) 用有机或有机元素配体 R 衍生化二元 Zintl 阴离子和三元金属间化合物簇，从而利用二元和三元体系的异极性，并根据通式 [RnMxE1yE2z]q- ( n,x大于/等于0)以形成新的金属间相。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；除了确定样品的特性外，这还应有助于阐明具有二元或三元金属间化合物 Zintl 阴离子的化合物的形成途径、稳定性和反应性，这是该领域进一步发展的关键问题。为了澄清无法通过实验技术解决的开放性问题，量子化学研究将是该项目的重要组成部分。这种高度复杂的综合和多方面分析的具体结合在过去已经取得了丰硕的成果，并将有助于未来计划研究的成功。
