SYNTHESES, CHARACTERIZATION, CRYSTAL STRUCTURES AND ANTIMICROBIAL PROPERTIES OF A NEW ORGANIC−INORGANIC HYBRID [4FBzTPP]2[CuBr4]

This article presents a study on the synthesis and character of a new organic-inorganic hybrid [4FBzTPP]2[CuBr4](1) ([4FBzTPP]+ is 4-fluorobenzyltriphenylphosphinium) by XRD, SEM, FT-IR and UV-Vis. The XRD analysis showed that the hybrid 1 belongs to the triclinic space group P21 with b = 8.8600(10) Å, c = 16.4867(17) Å, α = 16.639(2) °, β = 96.342(4) °, V = 2415.6(5) Å3, and Z = 2. The hybrid consists of two [4FBzTPP]+ cations and one [CuBr4]2– anion, and the [CuBr4]2– exhibits a twisted tetrahedral coordination geometry with the average bond length between Cu−Br is 2.393 Å. The 3D network structure of 1 is formed by electrostatic terms and other intermolecular interactions. The hybrid material undergoes a direct optical transition and has energy gap values of 1.66 eV and 2.18 eV, indicating its potential as a semiconductor material for optical research. The hybrid material undergoes a direct optical transition and has energy gap values of 1.66 eV and 2.18 eV, showing that the hybrid material is a potential semiconductor material for optical research. In addition, the compound exhibited good antibacterial activity against E. coli and S. aureus.
