We carried out neutron powder diffraction experiments on the cluster-based Haldane compound fedotovite K2Cu3O(SO4)3. Weak magnetic reflections caused by a magnetic long-range order appeared below an antiferromagnetic transition temperature TN =3.1 K. We propose a possible magnetic structure that is consistent with the magnetic properties reported in the literature.
