Abstract
One new coordination polymer, [{Ag 2L 3(BF 4) 2}H 2O] n ( 1), has been generated via self-assembly from the ligand L N, N′-bis(furan-2-ylmethylene)hydrazine and AgBF 4. The complex 1 and ligand L are characterized by single-crystal X-ray diffraction analysis. Crystal structure analyses show that the complex 1 belongs to the rhombohedral space group R 3 ¯ with a = 9.8999(6) Å, b = 9.8999(6) Å, c = 34.208(4) Å, V = 2903.5(4) Å 3 and the ligand L belongs to the orthorhombic space group Pbca with a = 6.9014(12) Å, b = 9.0215(16) Å, c = 15.235(3) Å, V = 948.5(3) Å 3. The structure of 1 exhibits a 2D layer hexagonal network with 18-Mc-6 [Ag 6L 6] metallacrowns as building blocks and every two adjacent silver atoms are bridged through the two nitrogen atoms of N–N bridge of a ligand. Luminescence studies revealed that L and complex 1 exhibit fluorescent emissions in the solid state at room temperature at λ max = 348 and 506 nm, respectively.
