While tetrazole derivatives are well established as anionic ligands for d-block elements, there is a growing interest in lanthanoid complexes of these compounds. Diverse structural chemistry results from the presence of four potential donor N atoms, and the conjugated nature of the heterocycle can impact on the photophysical properties of the complexes. This review examines the range of structurally characterised lanthanoid–tetrazolato complexes, focussing on the structural features of the ligand that impact on the tendency to interact with the first or second coordination spheres.

镧系四唑配位化合物

尽管四唑衍生物已被很好地确立为d-嵌段元素的阴离子配体，但人们对这些化合物的镧系元素络合物的兴趣日益增长。四个潜在的供体N原子的存在导致了不同的结构化学，并且杂环的共轭性质会影响复合物的光物理性质。这篇综述研究了结构特征化的镧系元素-四唑并合物的范围，重点研究了配体的结构特征，这些结构特征会影响与第一或第二配位体相互作用的趋势。
