Abstract

Maucherite Ni₁₁As₈ has been found to be an OD (order-disorder)structure consisting of unit layers, which display stackingorientation disorder. Maucherite is composed of OD layers ofone kind, with layer symmetry P( Formula

)m2(the bracketed element is perpendicular to the layer), the simplest,uniform stacking of which can result either in a tetragonalMDO1 structure with space-group type P4₁2₁2 or in a monoclinicMDO2 structure with space-group type C2/c. Beside these, polytypeswith more complicated or disordered stacking sequences may form.
