A series of polynuclear Cu(II) complexes were successfully synthesized under the reaction of Cu(NO3)2·3H2O, pyrazole-3,5-dicarboxylic acid, and various ancillary ligands and the structure-magnetic relationship of complexes was investigated.
One-dimensional metal–organic coordination polymers show high proton conductivities and excellent stabilities, mainly attributable to the coordination interactions/abilities of metal ions.
Seven new pyrazole-3,5-dicarboxylato Cu(II) complexes with 1,2-di(4-pyridyl)ethane were successfully synthesized under various conditions. Moreover, complex 1 exhibits structural transformation through a dissolution–recrystallization process.
A 3D coordination polymer of Tb(III) of formula [Tb(bttb)0.5(2,5-pzdc)0.5]n, where two polycarboxylate ligands act as linkers, exhibits a maximum relative sensitivity of 0.76% K−1 at 295 K.
A dysprosium–viologen framework featuring photoswitchable slow magnetic relaxation under a zero dc field has been constructed step-wise by the incorporation of photochromic layered motifs with the bridging ligand of 2,5-pyrazinedicarboxylate.
