Neutron powder-diffraction experiments on the highly Cr-substituted manganite, Nd_{0.6}Ca_{0.4}(Mn_{0.5}Cr_{0.5})O_3, at different temperatures and fields reveal that the structure retains the charge exchange-type of the parent compound, Nd_{0.6}Ca_{0.4}MnO_3. It is antiferromagnetic below 200 K and becomes a canted antiferromagnet below 50 K. The Mn and Cr form zig-zag ferromagnetic chains coupled antiferromagnetically in the ac-plane. These are stacked along the b-axis with opposite spins.
