Heterobimetallic [NiIILnIII] (Ln = Sm and Tb) N2O4-donor coordination polymers: Syntheses, crystal structures and fluorescence properties

Through the self-assembly of a 3-EtO salamo H2L with nickel acetate tetrahydrate, Lanthanide nitrate hexahydrate (Ln = Sm and Tb), and terephthalic acid (H2bdc), two new heterobimetallic [NiIILnIII] 3d-4f polymers, 2∞[Ni(L)Sm(bdc)1.5]·CH3OH (1) and 1∞[Ni(L)Tb(NO3)(DMF)(bdc)] (2) were synthesized, respectively.
