Research on single-molecule magnets involving monometallic 4f complexes has been conducted extensively in the past two decades, with the aim of understanding the factors governing slow magnetization relaxation and establishing a magneto-structural correlation. The main goal is to suppress the temperature independent quantum tunneling of magnetization effect by fine-tuning the coordination geometry. Investigating complexes containing high coordination number around Ln(III) has been relatively sparse, but various synthetic strategies have been used for assembling 10- and 12-coordinated Ln(III) complexes.
Single-molecule magnets involving monometallic 4f complexes have been investigated extensively in last two decades to understand the factors that govern the slow magnetization relaxation behavior in these complexes and to establish a magneto-structural correlation. The prime goal in this direction is to suppress the temperature independent quantum tunneling of magnetization (QTM) effect via fine-tuning the coordination geometry/microenvironment. Among the various coordination geometries that have been pursued, complexes containing high coordination number around Ln(III) are sparse. Herein, we present a summary of the various synthetic strategies that were used for the assembly of 10- and 12-coordinated Ln(III) complexes. The magnetic properties of such complexes are also described.
