Masquelet technique for the treatment of a severe acute tibial bone loss

Highlights • Synthetic strategies for heterometallic 3d–4f discrete complexes are proposed. • The nature of 3d and 4f electrons and its influence on syntheses and magnetic properties are analyzed. • Diverse structural topologies for 3d–4f single-molecule magnets (SMMs) are categorised and summarised. • The magnetic properties of 3d–4f SMMs are surveyed and summarised. • Magneto-structural correlations of 3d–4f SMMs are discussed to give basic rules for the design and synthesis of 3d–4f SMMs.
