Safflorite, (Co,Ni,Fe)As2, isomorphous with marcasite

Safflorite, a naturally occurring cobalt-nickel-iron diarsenide (Co,Ni,Fe)As2, possesses the marcasite-type structure, with cations (M = Co + Ni + Fe) at site symmetry 2/m and As anions at m. The MAs6 octahedra share two edges, forming chains parallel to c. The chemical formula for safflorite should...
