The crystal structure of Nd{sub 4}Cu{sub 2}O{sub 7} (monoclinic, space group A2/m, a = 8.4493(2) {angstrom}, b = 3.7591(1) {angstrom}, C = 12.6006(5) {angstrom}, {beta} = 109.576(4){degree}, Z = 2) prepared by topotactic reduction of the high-{Tc} superconductor parent phase Nd{sub 2}CuO{sub 4}, has been determined by Rietveld fitting of time-of-flight neutron powder diffraction data (R{sub wp} = 1.90%). A novel oxygen-vacancy-ordered arrangement of cooperatively distorted Cu{sub 2}O{sub 3} planes containing 2- and 4-coordinate Cu{sup +} sites is found.
