Powder neutron diffraction data on spin ladder compounds SrFe2Ch2O (Ch = S, Se) indicate that their magnetic ground states feature long‐range antiferromagnetic spin ordering with k = [0,0,0]. The superexchange interaction is antiferromagnetic across each rung via oxygen but ferromagnetic along the ladders via Ch. At 10 K, the ordered spins point towards the center of the ladders but are faintly canted...
