Abstract The crystal structure of hibbingite, natural γ-Fe 2+ 2 Cl(OH) 3 , a mineral of the atacamite group, was studied on a sample from the Oktyabr’sky mine, Norilsk district, Siberia, Russia. The structure was solved by direct methods based on single crystal X-ray diffraction data and refined to R =2.07% [520 reflections with I >2σ( I )]. The mineral is isostructural with atacamite and is orthorhombic, Pnma , a =6.3373(2), b =6.9892(2), c =9.3457(3) Å, V =413.95(3) Å 3 , Z =4. The structure contains Fe(1)(OH) 4 Cl 2 octahedra which share Cl–O(1) edges to form chains running along the b axis and cross-linked by the chains of Fe(2)(OH) 5 Cl octahedra sharing O(2)–O(2) edges and running along the a axis.
