Mn(II)/Co(II)-based metal-organic frameworks assembled by 5,5'-(1,4-xylylenediamino) diisophthalic acid and various nitrogen-containing ligands for photocatalytic and magnetic properties

A luminescent Zn(ii) coordination polymer based on a new tetrazolyl–benzimidazolyl tripodal heterotopic ligand for detecting acetone and triethylamine in water

“…Many ligands with different geometries and coordination groups have been used; among them, triangular ligands containing three nitrogendonor groups are versatile ligands used in the construction of porous MOFs, metal-organic cages, and so on. [6][7][8][9][10] To date, most N-containing triangular ligands possess three identical donor groups (homotopic ligands), whereas those containing different N-donor groups (heterotopic ligands) are still relatively less explored. [11][12][13][14][15] Considering that different N-donor groups usually display different coordination behaviours, heterotopic ligands may exhibit some new features in coordination chemistry that are different from those of their corresponding homotopic ligands.…”

Synthesis, structure, and magnetism of a novel series of trinuclear nickel(ii) clusters

“…Since the discovery of the first single-molecule magnet (SMM), [Mn 12 O 12 (OAc) 16 (H 2 O) 4 ], polynuclear coordination clusters containing paramagnetic metal centers have attracted considerable interest due to their potential application as a new type of magnetic material. [1][2][3][4][5][6][7][8][9][10] For designing SMMs, magnetic anisotropy plays an important role in governing the magnetic behavior. Slow magnetic relaxation and quantum tunneling of the magnetization in clusters are primarily controlled by the nature and magnitude of the magnetic anisotropy in their ground spin state.…”

“…32,33 The design and synthesis of stable nickel(II) complexes using H 3 fshz and exploring their magnetic properties remain a significant challenge. Herein, we report the synthesis, crystal structure, and magnetic properties of five novel linear trinuclear Ni(II) complexes based on the H 3 fshz ligand: Ni 5). Magnetic studies revealed a large magnetic anisotropy and a weak antiferromagnetic exchange coupling between the metal ions.…”
