A 3D cadmium–vanadium bimetallic framework with luminescence properties

Abstract

Herein, a novel cadmium–vanadium bimetallic framework, [(en)Cd2V2O7] (1) (en = ethylenediamine), was hydrothermally synthesized and characterized via IR spectroscopy, elemental analysis, powder X-ray diffraction, thermogravimetric analysis, and X-ray single-crystal diffraction. Compound 1 shows an intriguing 3D framework possessing a pillared layer, in which CdO5N octahedra are corner-shared to generate a 2D layer with 4-membered rings and further extended into a 3D framework. The most fascinating feature of the framework is the connection between layers through double bridges: inorganic V2O7 dimers and organic en molecules. Note that inorganic and organic double linkers between layers have been first observed in cadmium vanadates. The luminescence properties illustrate an intense, broad emission maximum at λ ≈ 475 nm due to O → V charge transfer in the VO4 units.
