摘要：
An organically templated iron(II) sulfate of the composition [H3N(CH2)(2)NH2(CH2)(2)(NH3](4)[(Fe9F18)-F-II(SO4)(6)], 9H(2)O with a distorted Kagome structure has been synthesized under solvothermal conditions in the presence of diethylenetriamine. The distortion of the hexagonal bronze structure comes from the presence of two different types of connectivity between the FeF4O2 octahedra and the sulfate tetrahedra. This compound exhibits magnetic properties different from those of an Fe(II) compound with a perfect Kagome structure and is a canted antiferromagnet at low temperatures.
