The structure and spectral properties of two copper bearing 14 xocomecatlite and tlapallite are compared with an iron bearing rodalquilarite mineral. 15 Two prominent bands observed at 9855 and 9015 cm-1 are 16 2 2 2 2 2+ 17 assigned to B1g → B2g and B1g → A1g transitions of Cu ion in xocomecatlite. 18 19 The cause of spectral distortion is the result of many cations of Ca, Pb, Cu and Zn the 20 in tlapallite mineral structure. Rodalquilarite is characterised by ferric ion absorption 21 in the range 12300-8800 cm-1. 22 Three water vibrational overtones are observed in xocomecatlite at 7140, 7075 23 and 6935 cm-1 where as in tlapallite bands are shifted to low wavenumbers at 7135, 24 7080 and 6830 cm-1. The complexity of rodalquilarite spectrum increases with more 25 number of overlapping bands in the near-infrared. -
Iseite, Mn2mo3o8, a New Mineral from Ise, Mie Prefecture, Japan

It is the first mineral species that includes both Mn and Mo as essential constituents. Iseite is iron-black in color and has a submetallic luster. It occurs as ag- gregates up to about 1 mm in size made of minute crystals (<20 μm). Iseite has a zoned structure closely associ- ated with undetermined Mn-Fe-Mo oxide minerals with hexagonal forms, and it occasionally coexists with 3 small amounts of powellite. Its Mohs hardness is 4-5, and its calculated density is 5.85 g/cm . The empirical formula of iseite is (Mn1.787Fe0.193)Σ1.980Mo3.010O8. Its simplified ideal formula is written as Mn2Mo3O8. The min- eral is isostructural with kamiokite (hexagonal, P63mc). The unit cell parameters are a = 5.8052 (3) Å, c = 10.2277 (8) Å, V = 298.50 (4) Å3, and Z = 2. The Rietveld refinement using synchrotron radiation (λ = 0.413 Å) powder XRD data converges to Rwp = 3.11%, and confirms two independent Mn sites—tetrahedral and octahe- IV VI dral—in the crystal structure of iseite, indicating the structure formula Mn Mn Mo3O8. -

Rinmanite crystals are prismatic, up to 0.5 mm in length, with good {100} cleavage. The VHN100 –3 is in the range 841–907. Dcalc = 5.13(1) g•cm . The mineral is black (translucent dark red in thin splinters) with a submetallic luster. The mineral is moderately anisotropic and optically uniaxial (–). Reflectance values measured in air are 13.5–12.1% ( = 470 nm), 12.9–11.8% (546 nm), 12.6–11.7 (589 nm) and 12.2–11.3% (650 nm). Electron-microprobe analyses of rinmanite (wt.%) gave MgO 8.97, Al2O3 0.82, MnO 2.47, Fe2O3 34.33, ZnO 14.24, Sb2O5 36.31, H2O 1.99 (calculated), sum 99.13, yielding the empirical formula (Zn1.58Mn0.31Mg0.06)⌺1.95Sb2.03[Mg1.95Fe3.88Al0.15]⌺5.98O14.01(OH)1.99.
