摘要：

Open-framework ammonium ferricborophosphate compound was synthesized by mild hydrothermal condition at 110degreesC. The crystal structure has been determined by single-crystal X-ray diffraction analysis: hexagonal, P6(5)22, a = 9.452(2) Angstrom, c = 15.698(5) Angstrom, alpha = 90degrees, gamma = 120degrees, Z = 6, M-r = 310.58, V = 1214.0(5) Angstrom(3), D-c = 2.549 g/cm(3),mu = 2.311mm(-1), F(000) = 930. The chiral tetrahedral-tetrahedral helical ribbons are linked by the mixed valance Fe-II/(FeO6)-O-III coordinated octahedra. The ammonium ions are located inside the free loop of helical ribbons close to the inner wall of the helical channels (-)(infinity) {[BP2O8](3-)}, effecting on balancing charge and stabilizing helical ribbons.
