Abstract

A pair of luminescent heterometallic lanthanide-transition-metal coordination polymers, namely, [PrLAg3(SCN)6·H2O]n (1) and [PrLAg3(SCN)6]n (2) [L = 2,6-di(pyrazol-1-yl)pyridine], have been obtained with different cooling rates under solvothermal conditions. The two structures are pseudo- supramolecular isomers constructed via the same [PrL(NCS)6]3− subunit and different Ag–S clusters, presenting diverse two-dimensional and three dimensional frameworks, respectively. In both complexes, the tridentate chelate L, acting as an organic chromophore, along with the d10-block Ag–S clusters, are simultaneously immobilized, and effectively sensitize the PrIII-based luminescence.
