Hetero-metallic Lanthanide CPs Involving Sodium: Synthesis, Crystal Structure, and Luminescence Properties

[TbNa(4-msal) 4 (phen) 2 ] n ( 1 ) (4-msal = 4-methyl salicylic acid), a new hetero-metallic lanthanide coordination polymer (CP) involving sodium was synthesized. It crystallizes in the monoclinic space group P 2 1 / n , with a = 20.4809(9) Å, b = 9.8183(2) Å, c = 26.1987(11) Å, α = 90.00°, β = 112.922(5)°, γ = 90.00°, V = 4852.2(3) Å 3 , and Z = 4. The complex was characterized by single crystal and powder X-ray diffraction, elemental analysis (EA), and Fourier transform infrared (FT-IR) and luminescence spectroscopy. The luminescence properties of a powder sample of 1 were studied at room temperature and the luminescence lifetime and total quantum yield (QY) were determined.
