    Description / Table of Contents: Summary Electron microprobe analysis of the new mineral johillerite gave Na2O 5.4, MgO 18.3, ZnO 5.4, CuO 15.8, and As2O5 55.8, total 100.7%. From this result, the ideal formula is given as Na(Mg, Zn)3 Cu(AsO4)3. Johillerite crystallizes monoclinic,C2/c. The unit cell dimensions are:a=11.870(3),b=12.755 (3),c=6.770 (2) Å, β=113.42 (2)°,Z=4. The strongest lines on the X-ray powder diffraction pattern are: 4,06 (5) (22 $$\bar 1$$ ), 3,50 (4) (310), 3,25 (8) (11 $$\bar 2$$ ), 2,75 (10) (330, 240), 2,64 (5) (311, 13 $$\bar 2$$ , 40 $$\bar 2$$ ), 1,952 (4) (13 $$\bar 3$$ , 35 $$\bar 2$$ ), 1,682 (4) (20 $$\bar 4$$ , 460), 1,660 (5) (40 $$\bar 4$$ , 71 $$\bar 1$$ , 550, 64 $$\bar 2$$ ), 1,522 (4) (442, 153, 13 $$\bar 4$$ ). There is a close relationship between johillerite, o'danielite, Na(Zn, Mg)3H2(AsO4)3, and some synthetic compounds. Johillerite is violet in colour, transparent. Cleavage is {010} perfect, {100} and {001} good.H (Mohs)∼3.D=4.15 andD X =4.21 g·cm−3. The mineral is optically biaxial positive, 2V∼80 (5)°. The refractive indices are:n α=1.715 (4),n β=1.743 (4),n γ=1.783 (4). The extinction isn γ‖b and on (010)n α⋏c∼16°. Strongly pleochroic with axial coloursX=violet-red,Y=bluish violet andZ=greenish blue. The new mineral was found in radiated masses together with cuprian adamite and conichalcite in an oxidized copper ore from Tsumeb, Namibia. It is named in honour of Prof. Dr.J.-E. Hiller (1911–1972).
    Notes: Zusammenfassung Die chemische Analyse des neuen Minerals Johillerit mit der Elektronenmikrosonde ergab: Na2O 5,4, MgO 18,3, ZnO 5,4, CuO 15,8 und As2O5 55,8, Summe 100.7%. Aus diesem Ergebnis wurde die idealisierte Formel Na(Mg, Zn)3 Cu(AsO4)3 abgeleitet. Johillerit ist monoklin mit der RaumgruppeC2/c. Die Gitterkonstanten sind:a=11,870 (3),b=12,755 (3),c=6,770 (2) Å, β=113,42 (2)°,Z=4. Die stärksten Linien des Pulverdiagramms sind: 4,06 (5) (22 $$\bar 1$$ ), 3,50 (4) (310), 3,25 (8) (11 $$\bar 2$$ ), 2,75 (10) (330, 240), 2,64 (5) (311, 13 $$\bar 2$$ , 40 $$\bar 2$$ ), 1,952 (4) (13 $$\bar 3$$ , 35 $$\bar 2$$ ), 1,682 (4) (20 $$\bar 4$$ , 460), 1,660 (5) (40 $$\bar 4$$ , 71 $$\bar 1$$ , 550, 64 $$\bar 2$$ ), 1,522 (4) (442, 153, 13 $$\bar 4$$ ). Es bestehen enge strukturelle Beziehungen zwischen Johillerit und O'Danielit, Na(Zn, Mg)3H2(AsO4)3, sowie einigen synthetischen. Verbindungen. Johillerit ist violett durchscheinend. Die Spaltbarkeit nach {010} ist ausgezeichnet und nach {100} und {001} gut.H (Mohs)∼3.D=4,15 undD X =4,21 g·cm−3. Das Mineral ist optisch zweiachsig positiv, 2V∼80 (5)°. Die Werte der Lichtbrechung sindn α=1,715 (4),n β=1,743 (4) undn γ=1,783 (4). Die Auslöschung istn γ‖b und auf (010)n α⋏c≃16°. Johillerit ist stark pleochroitisch mit den AchsenfarbenX=violett-rot,Y = blauviolett undZ = grünblau. Das neue Mineral kommt in radialstrahligen Massen gemeinsam mit kupferhaltigem Adamin und Konichalcit in zersetzem Kupfererz von Tsumeb, Namibia, vor. Die Benennung erfolgte nach Prof. Dr.J.-E. Hiller (1911–1972).

    Description / Table of Contents: Summary The crystal structure of the new mineral warikahnite, Zn3[(H2O)2|(AsO4)2], was determined from diffractometer data and refined toR=0,038 for 3428 observed independent reflections. Warikahnit is triclinic, $$P\bar 1$$ , witha=6.710(1),b=8.989(2),c=14.533(2) Å, α=105.59(1), β=93.44(1), γ=108.68(1)°,Z=4. The crystal structure of warikahnite contains 6 different coordination polyhedra of zinc with the coordination numbers 6,5 and 4 and with 5 different combinations of ligand. The hydrogen bonds are discussed on the basis of charge balance and IR spectra.
    Notes: Zusammenfassung Die Kristallstruktur des neuen Minerals Warikahnit, Zn3[(H2O)2|(AsO4)2], wurde mit Diffraktometerdaten bestimmt und bis zuR=0,038 für 3428 unabhängige Reflexe verfeinert. Warikahnit ist triklin, $$P\bar 1$$ , mita=6,710(1),b=8,989(2),c=14,533(2) Å, α=105,59(1), β=93,44(1), γ=108,68(1)°,Z=4. Die Kristallstruktur des Warikahnits enthält sechs unterschiedliche Koordinationspolyeder des Zinks mit den Koordinationszahlen 6, 5 und 4 und mit fünf verschiedenen Ligandenkombinationen. Die Wasserstoffbrückenbindungen werden mit Hilfe der Ladungsbilanz und des IR-Spektrums diskutiert.

    Description / Table of Contents: Summary Electron microprobe analysis of the new mineral lammerite gave CuO 49.9, ZnO 0.8, MgO 0.2, FeO 0.2, and As2 O5 49.8, total 100.9%. From this result, the ideal formula is given as Cu3[AsO4]2. Lammerite crystallizes monoclinic. The possible space groups areP21 orP21/m. The unit cell dimensions are:a=5.080(2),b=11.616(6),c=5.391(2) Å, β=111.71(3)°,Z=2. The strongest lines on the X-ray powder diffraction pattern are: 4.06(5) ( $$11\bar 1$$ , 3.80(6) (021), 3.06(8) (031), 3.00(8) (130), 2.89(10) (040, $$13\bar 1$$ ), 2.84(7) (111), 2.62(8) (121), 2.59(8) ( $$11\bar 2$$ ), 2.52(9) ( $$20\bar 1$$ , 041), 2.09(5) (150), and 1.582(6) ( $$25\bar 2$$ , 241). Lammerite is dark green transparent. The crystals are tabular on {100} and intergrown as radiated aggregates. Cleavage is {010} perfect, {100} good and {001} traces. The mineral is optically biaxial positive, 2V∼54±5°. The refractive indices are:n α≲1.89,n β=1.90, andn γ=1.95. Pleochroism strong and axial coloursX=very pale blue,Y=sky blue, andZ=pale bluish green. The extinction isn α‖b and on (010)n γ⋏c∼40°.H (Mohs)∼3.5–4.D=5.18 andD X =2.26 g·cm−3. Lammerite is associated with olivenite and an other proposed new mineral. The type material has been found at Veta Negra, Laurani, Bolivia.
