Аннотация
Hydrothermal syntheses of 2-carboxyethyl(phenyl)phosphinic acid (H2CEPPA) with Bi(NO3)3 and Cd(NO3)2 produce two layered complexes [Bi2(μ3-O)(CEPPA)2]n (1) and [Cd(HCEPPA)2]n (2). Compound 1 is comprised of [Bi4(μ3-O)2(POO)4(COO)4] SBUs which grow into a double wave-like 2D layer with–CH2CH2–spacers. Compound 2 crystallizes in the orthorhombic noncentrosymmetric space group Pca21, exhibiting a double lattice-like layer. Through edge-to-face d∙∙∙π stacking, a 3D supramolecular framework is formed based on 2D lattices. Topological analyses indicate that 1 and 2 have sql (or Shubnikov tetragonal plane net) and kgd (or Shubnikov (3.6.3.6) plane net) topological networks respectively. 1 and 2 are isolated as single crystal pure phases, which is confirmed by powder XRD. TGA shows high thermal stabilities with decomposition temperatures of 1 and 2 being 373 and 303°C respectively. The fluorescent spectra exhibit fluorescence quenching in 1 and sharp emission at 292 nm in 2, which is assigned to intraligand emission.
