The key aims of this student project are to synthesise novel, mixed transition metal complexes and to fully characterise them (techniques including single crystal X-ray diffraction, powder X-ray diffraction, mass spectrometry, nuclear magnetic resonance and others). The primary synthetic target will be magnetically interesting molecular materials by extending a "family" of previously reported heptanuclear mixed metal wheels. As such, magnetic characterisation will be carried out using a SQUID (Superconducting QUantum Interference Device) magnetometer. This data will be analysed and a theoretical model created to fit the data. By investigating a range of related complexes this research seeks to contribute to modern understanding of magneto-structural relationships and aid in the development of a synthetic rationale towards complexes with desirable magnetic properties. One such desirable target are single molecule magnets (SMMs). SMMs are prophesised to contribute greatly to the second quantum revolution. Due to the quantum nature of their magnetic properties, single molecule magnets are well suited to form the hardware of quantum computers, which can perform calculations in minutes and hours that would take modern, classical computers billions of years. The synthetic aspect of this project also seeks to synthesise solution-stable magnetic complexes, which yields more technologically applications by facilitating post synthetic modifications and generally increasing their processability. Solution stable multinuclear complexes also have the potential for use in catalysis. Given the large number of metal centres present the complexes to be investigated (ie. 7 metals centres) it is possible they could catalyse the oxidation of water, which is useful to work towards artificial photosynthesis. Therefore, when appropriate the electrochemical properties of these complexes will be studied to assess their suitability to this process.

该学生项目的主要目标是合成新型的混合过渡金属络合物并对其进行充分表征（包括单晶X射线衍射，粉末X射线衍射，质谱，核磁共振等技术）。主要的合成目标将是磁感兴趣的分子材料，通过扩展以前报道的七核混合金属轮的“家庭”。因此，将使用SQUID（超导量子干涉装置）磁力计进行磁性表征。将对这些数据进行分析，并创建一个理论模型来拟合这些数据。通过研究一系列相关的配合物，这项研究旨在促进现代理解的磁结构关系，并帮助发展一个合成的理由，对配合物具有理想的磁性。一种这样的期望靶是单分子磁体（SMM）。SMM被预言将为第二次量子革命做出巨大贡献。由于其磁性的量子性质，单分子磁体非常适合形成量子计算机的硬件，它可以在几分钟和几小时内执行计算，而现代经典计算机需要数十亿年。该项目的合成方面还寻求合成溶液稳定的磁性复合物，通过促进合成后修饰和普遍提高其可加工性来产生更多的技术应用。溶液稳定的多核配合物在催化方面也有潜在的应用。考虑到大量的金属中心存在的配合物进行研究（即。7金属中心），它们可能催化水的氧化，这对人工光合作用很有用。因此，在适当的情况下，将研究这些络合物的电化学性质，以评估其对该过程的适用性。
