Transition metal phosphite complexes: from one-dimensional chain, two-dimensional sheet, to three-dimensional architecture with unusual magnetic properties

Heterometallic Hexanuclear [Ln4Cr2] Cluster-Based Three-Dimensional Sulfate Frameworks as a Magnetic Refrigerant and Single Molecular Magnet

“…Research of open-framework inorganic compounds based on anionic [TO 4 ] units (T = tetrahedral coordination atoms) has increasingly aroused researchers’ interest for their varieties of engaging structural topologies and various applications. − To date, the study on such frameworks has been concentrated on metal phosphates, phosphites, , selenate, , selenites, − and sulfates, ,, of which the sulfate systems are an important family. SO 4 2– can coordinate with transition (3d) or lanthanide (4f) metal ions with multifarious modes.…”
