About KaribibiteHide

Formerly given as Fe2As4O9.
Crystal System:
Named for the type locality.
A rare iron arsenite. So far, it always originated as a weathering product of löllingite.
Visually similar to ludlockite.
Compare also 'UM1971-02-AsO:Fe'.

The structure seems to have been solved just recently (Mugnaioli, 2016; Colombo et al., 2017). The mineral is unique in being the only arsenite with structurally different anions (chains and dimers simultaneously), and is a representative of a small class of diarsenates(III) (or diarsenites).

Structure details:
(1) Fe3+O6 octahedra form bands along a; the bands are made of ribbons built of 3 edge-sharing octahedra, and the ribbons are joined via apices to give a kinked bond along a;
(2) the above bands are surrounded by (a) chains comprising AsO3 trigonal pyramids, and (b) As2O5 dimers;
(3) the dimers are connected by the O(3) atoms, thus giving zig-zag chains of the (As3+O2)-n stoichiometry.
