dc.description.abstract | Lone pair cation-based novel coordination compounds Sn[(pdc)(H2O)] (Sn-I) and (H2bpy)[Bi(pdc)2(Hpdc)]·5H2O (Bi-I) (pdc = pyridine-2,6-dicarboxylate; bpy = 4,4′-bipyridine) were synthesized through mild hydrothermal reactions. While Sn-I crystallizing in the polar space group, Pca21, exhibits a helical chain structure consisting of SnO3N distorted seesaws, 2,6-pdc linkers, and water molecules, Bi-I crystallizing in the centrosymmetric (CS) space group, P1¯, reveals a pseudo-3D network composed of BiO5N3 polyhedra, 2,6-pdc ligands, H2bpy2+ cations, and isolated H2O molecules. The lone cations Sn2+ and Bi3+ in the title compounds are in a highly deformed polyhedral environment. The single-crystal-to-single-crystal transformation from Sn-I to the anhydrous Sn[(pdc)] (Sn-II) with the polar noncentrosymmetric structure was successfully achieved upon heating crystals of Sn-I. UV-vis diffuse reflectance spectra indicate that the introduction of Sn2+ or Bi3+ red-shifts the adsorption edges upon coordination. Powder second-harmonic generation (SHG) measurements indicate that Sn-I and Sn-II are type-I phase-matchable and exhibit SHG intensity of ca. 15 and 35 times that of α-SiO2, respectively. Solid state photoluminescence (PL) measurements indicate that Bi-I is an excellent green emitting phosphor with the quantum efficiency up to 26% and outstanding decay lifetime of 1.82 ms at room temperature. © 2020 American Chemical Society. | - |
