Hydrothermal Synthesis, Structure, Properties of a Novel Supramolecular Complex: [LaCd(bpy)₄(NO₃)₅]

A novel lanthanum cadmium complex [LaCd(bpy)₄(NO₃)₅] (where bpy = 2,2′-Bipyridine) has been synthesized and structurally characterized by X-ray diffraction method, elemental analysis, spectral method (IR), powder X-ray diffraction (XRD), electronic spectra (UV–vis) and photoluminescence properties. The complex crystallizes in the monoclinic space group P21/c with unit cell parameters a = 16.883(2) Å, b = 14.382(2) Å, c = 18.981(3) Å, β = 96.806(2), V = 4576.5(11) ų, and Z = 4. The complex is completed by two crystallographically and chemically independent, octahedrally coordinated Cd(II) ion and icosahedronly coordinated La(III) ion. The electronic spectra and photoluminescence of the complex has been described.[Supplemental materials are available for this article.
