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 Pr^III-based luminescence.
