009ChemInform Abstract The title mineral (from the former mine "Gruene Aue", Siegerland) crystallizes in the orthorhombic system, space group P212121, Z=4. In its structure, a new type of ABCX3 compound, the Bi atom and its three nearest S atoms form a trigonal pyramid. The polyhedron, which results from consideration of a fourth S atom at a greater distance, is very similar to the TeO4 polyhedron in Zn2Te3O8. Cu and Ni can either occupy the M(1) position (tetrahedrally coordinated by S) or the M(2) position (coordinated by four S in the quadratic base and two Bi at the vertices of a tetragonal bipyramid). Crystal chemical considerations show the M(1) and M(2) positions to be occupied by Cu and Ni, respectively.
