Structural diversity, photoluminescence and magnet properties of complexes based on a V-shaped polycarboxylate

Complexes 1-4 exhibit different structures ranging from discrete entities to three-dimensional frameworks based on bi-, tri-, tetra- and pentanuclear clusters as subunits, which demonstrates various coordination modes of the H4dstc ligand and the roles of the auxiliary ligands as well as the metal ions in engineering the resultant network. Additionally, the magnetic properties of 1 and 3 and the luminescent property of 4 have been studied.
