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, FTIR 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.
