IMA Classification of Ixiolite-(Mn2+)
Approved
IMA status notes:
Redefined by the IMA
IMA Formula:
(Ta2/3Mn2+1/3)O2
Approval history:
The old “ixiolite” has been redefined and results now in two distinct mineral species: ixiolite-(Mn2+), with end-member formula (TaMn)O2, and ixiolite-(Fe2+), with end-member formula (TaFe)O2. The type locality for both is Skogsböle, Kimito Island, Finland.
Classification of Ixiolite-(Mn2+)
4.DB.25
4 : OXIDES (Hydroxides, V[5,6] vanadates, arsenites, antimonites, bismuthites, sulfites, selenites, tellurites, iodates)
D : Metal: Oxygen = 1:2 and similar
B : With medium-sized cations; chains of edge-sharing octahedra

(Ta0.67Mn2+0.33)O2
Elements listed:
Crystallography of Ixiolite-(Mn2+)
Crystal System:
Orthorhombic
Cell Parameters:
a = 4.785 Å, b = 5.758 Å, c = 5.160 Å
Ratio:
a:b:c = 0.831 : 1 : 0.896
Unit Cell V:
142.17 ų (Calculated from Unit Cell)
Comment:
Nickel et al. (1963) give space group Pcan (non-standard setting) and unit-cell parameters a = 5.731, b = 4.742, c = 5.152 Å. Grice et al. (1976) give space group Pbcn (non-standard setting) and the unit-cell parameters a = 4.785, b = 5.758, c = 5.160 Å (used above). Heating usually produces an ordered wodginite-type structure.
