The spiral magnetic structure and underlying spin lattice of BiMnFe2O6 are investigated by low-temperature neutron powder diffraction and density functional theory band structure calculations. In spite of the random distribution of the Mn3+ and Fe3+ cations, this centrosymmetric compound undergoes a transition into an incommensurate antiferromagnetically ordered state below TN ~ 220 K.The magnetic structure is characterized by the propagation vector k = [0,β,0] with β~0.14 and the P221211´(0β0)0s0s magnetic superspace symmetry.
