Abstract 2 O) K]Mn2 (Al2 Ti)(PO4) 4 (OF)(H2 O) 10 ⋅ 4 H2 O, is a new monoclinic member of the paulkerrite group, from the Hagendorf-Süd pegmatite, Oberpfalz (Upper Palatinate in English), Bavaria, Germany. It occurs on the walls of vugs in corroded zwieselite, in association with Zn- and Al-bearing earlshannonite, fluorapatite, jahnsite-(CaMnMn) and Al-rich strunzite. Fluor-rewitzerite forms clusters of colourless stubby prisms up to 0.1 mm long that are flattened on { 010 }; elongated along [100]; and show the forms { 100 }, { 010 }, { 001 }, { 111 } and { 11 1 ‾ }. Twinning occurs by 2-fold rotation about c - 3 + α = β = γ = V = A 1 2 O) 0.85 K0.15 ]Σ 1.00 A 2 1.00) M 1 2 + 1.50 Mg0.09 Fe2 + 0.41)Σ 2.00 M 2 + M 3 1.70 Ti4 + 0.89 Fe3 + 0.42)Σ 3.01 4) 3.99 X (O1.09 F0.92)Σ 2.01 2 O) 10 ⋅ 4.12 H2 O. Fluor-rewitzerite has monoclinic symmetry with space group P 1/c a = b = c = β = V = 3 and Z = R obs = 0.058 for 6186 reflections with I > 3 σ (I). Fluor-rewitzerite is the fluoride analogue of rewitzerite, with F dominant over OH at the X A A M 2 M 22 M 3 (PO4) 4 X 2 2 O) 10 ⋅ 4 H2 O.
