The first hybrid Bi(III) supramolecular compound based on organic ammonium and 18-crown-6, [(4-FBNH3)3·(18-crown-6)3·(Bi2Cl9)] (1), has been synthesized and characterized by single crystal X-ray diffraction, elemental analysis, IR, XRPD and 1H NMR (4-FBNH3 = 4-fluorobenzenaminium). The Bi(III) centers were chelated through three μ2-Cl donors to form a macro-anion (Bi2Cl9)3− unit. And the rotator-stator assembly, [(4-FBNH3)·(18-crown-6)]+, was formed by the 4-FBNH3+ cation inserting into the crown ether through strong NH…O H-bonding interactions. The large anions and rotator-stator cations were alternately stacked together to build the supramolecular functional compound. In addition, the thermal analysis and luminescent properties were investigated.
