Based on the inherent contribution of the d–f electrons and the unique exchange interactions between different metal ions, heterometallic lanthanide–transition metal (d–f) clusters have received substantial attention in modern chemistry. In the past two decades, numerous lanthanide–transition metal clusters with diverse molecular structures have been obtained. Various synthetic approaches have been developed by analyzing the crystal structures and reaction conditions. In this chapter, we discussed synthetic methodology based on hard and soft acids and bases (HSAB) theory and the resulting structures. In addition, personal perspectives and outlooks regarding the future research directions of d–f molecular clusters are provided at the end of this chapter.
