The crystal structure of a new sulphosalt, jaskolskiite, Cu, Pb2 + * (Sb, Βϊ)2-* S5 (Χ Κ 0.2), has been determined. The space group is Pbnm, witha = 11.312(2), b = 19.829(3),c = 4.088(1)Ä,Z = 4 for the composition Cu0.i9 Pb2.22 Sb 1 1 7 Bio.62 S5. The structure has been solved using its homologous relationship to meneghinite and refined from three-dimensional difTractometer data to an Ä-value of 0.072 for 472 observed reflections. The structure consists of slices (010) of SnS-like arrangement mutually related by the «-glide planes and wavy interfaces. The metal positions Μ1 and Μ 4 inside the slices represent Sb sites partly substituted by Bi and Pb. The Μ 2 and Μ 3 positions are on the surfaces of slices and represent Pb sites with some substitution by Bi in the case of M2. The tetrahedral sites in the slice interfaces are partially occupied by Cu. Jaskolskiite represents the 4th member of the meneghinite homologous series. The published chemical and structural data for the known homologues of meneghinite, with Ν = 1, 2, (3), 4 and 5, are systematized in the paper.
