Three incommensurately modulated γ‐brass‐related composite structures in the Ni–Zn system have been solved from X‐ray single crystal diffraction data using a 3+1 dimensional super space description. The compounds at the end points of the compositional domain NiZn 3– δ (–0.09 ≤ δ ≤ 0.34) and NiZn 3.30 crystallize in the orthorhombic superspace group Fmmm (α00)0s0 { F = [(1/2, 1/2, 0, 0); (1/2, 0, 1/2, 0); (0, 1/2, 1/2, 0)]} with the following fundamental cell dimensions a = 4.165(1) Å, b = 8.883(2) Å, c = 12.545(3) Å, q ≈ 0.6311 a *; a = 4.161(2) Å, b = 8.876(3) Å, c = 12.535(4) Å, q ≈ 0.6314 a * and a = 4.177(2) Å, b = 8.899(1) Å, c = 12.570(2) Å, q ≈ 0.6378 a *.
