摘要

An open-framework ammonium ferricborophosphate compound was synthesized by mild hydrothermal condition at 110°C. The crystal structure has been determined by single-crystal X-ray diffraction analysis: hexagonal, P6 522, a = 9.452(2) Å, c = 15.698(5) Å, α = 90°, γ = 120°, Z = 6, Mr = 310.58, V = 1214.0(5) Å 3, Dc = 2.549 g/cm3, μ = 2.311 mm -1, F(000) = 930. The chiral tetrahedral-tetrahedral helical ribbons are linked by the mixed valance FeII/FeIIIO6 coordinated octahedra. The ammonium ions are located reside the free loop of helical ribbons close to the inner wall of the helical channels ∞ 1 {[BP2O8]3-}, effecting on balancing charge and stabilizing helical ribbons.
