Аннотация
Single-crystal study of the structure (R = 0.0268) was performed for garyansellite from Rapid Creek, Yukon, Canada. The mineral is orthorhombic, Pbna, a = 9.44738(18), b = 9.85976(19), c = 8.14154(18) Å, V = 758.38(3) Å3, Z = 4. An idealized formula of garyansellite is Mg2Fe3+(PO4)2(OH) · 2H2O. Structurally the mineral is close to other members of the phosphoferrite–reddingite group. The structure contains layers of chains of M(2)O4(OH)(H2O) octahedra which share edges to form dimers and connected by common edges with isolated from each other M(1)O4(H2O)2 octahedra. The neighboring chains are connected to the layer through the common vertices of M(2) octahedra and octaahedral layers are linked through PO4 tetrahedra.
