Regerite, KFe<sub>6</sub>(PO<sub>4</sub>)<sub>4</sub>(OH)<sub>7</sub>(H<sub>2</sub>O)<sub>6</sub>  ⋅  4H<sub>2</sub>O, the first new mineral species from the Kreuzberg pegmatite, Pleystein, Oberpfalz, Bavaria, Germany
Abstract 6 (PO4) 4 7 (H2 O) 6 ⋅ 2 O, is the first new mineral species to be characterised from the Kreuzberg pegmatite, Pleystein, in the Oberpfalz, Bavaria. It was found in vugs on a specimen of drusy quartz, associated with rockbridgeite, strengite and phosphosiderite. Regerite occurs as clusters of yellowish-green prisms, typically 5 to 20 µ m wide and up to 0.1 mm long. The crystals are flattened on { 100 } and elongated along [001], and they display the forms { 100 }, {010} and {011}. The measured density is 2.69 (2) g cm- 3 +), with α = 1.670 (5), β = 1.690 (5) and γ = 1.730 (5) (measured in white light), and 2V ∘. The empirical formula from electron microprobe analyses and crystal structure refinement is K0.95 (Fe5.66 3 + Ti0.45) Σ 6.11 (PO4) 3.95 7 [(H2 O) 5.33 (OH) 0.88 ]Σ 6.21 ⋅ 2 O. Regerite has monoclinic symmetry, with space group P 2 1/c and unit-cell parameters a = 15.408 (11) Å, b = 17.311 (11) Å, c = 9.870 (11) Å, β = 95.42 (2) ∘, V = 2621 (3) Å3 and Z = 4. The crystal structure was refined using synchrotron single-crystal data to w R obs = 0.065 for 6088 reflections with I > 3 σ (I). The structure type has not been previously reported. It is made of heteropolyhedral layers parallel to { 100 } that consist of Fe-centred octahedra and PO4 tetrahedra. The layers are interconnected via edge-shared octahedral dimers to form slit-like channels along [001] that are occupied by K+ ions and water molecules.
