A new organobismuth (V) complex with fluorobenzoic ligands: Synthesis, crystal structure, photodegradation properties

A new Organobismuth (V) complex, Ph 3 Bi(4-fbc) 2 [4-fbc = 4-fluorobenzoic carboxyl] was synthesized. The structure of the complex was characterized by IR spectra, elemental analysis, powder X-ray diffraction (PXRD) and single-crystal X-ray diffraction. Single crystal X-ray diffraction analysis reveals that the complex displays an 1D straight chain structure by the intermolecular hydrogen bonds (C-H⋯F and C-H⋯O), which are further constructed by π-π stacking interactions to form 2D layer and by crystal packing to form 3D supramolecular networks. Furthermore, the photodegradation properties of the complex has been investigated in organic dyes (RhB, MV, MB) and the results show that the complex has the best photocatalytic activity for RhB. The tentative photocatalytic degradations mechanism also has been discussed in details.
