Аннотация

Neyite Ag2Cu6Pb25Bi26S68 was identified in the dumps of Yugo-Konevo tungsten deposit (Chelyabinsk oblast, Southern Urals) for a first time in Russia. This rare sulfosalt forms prismatic crystals up to 3 х 0.5 mm in fluorite-muscovite-quartz veins and is associated with aikinite, tetradymite and pyrite. Reflectance spectra and values of neyite are published for the first time. The chemical composition of neyite is (wt. %, electron microprobe, mean of 7 analyses): Ag 1.75, Cu 3.59, Pb 35.01, Cd 0.12, Bi 42.59, S16.54, total 99.60. The empirical formula calculated based on S = 68 atoms per formula unit is Ag2.14Cu7.45Pb22.27Cd0.14Bi26.86S68. The crystal structure of neyite from Yugo-Konevo was refined on the single crystal, R1 = 3.43 %, wR2 = 7.22 %. The mineral is monoclinic, space group С2/m, a = 37.3900(6) Å, b = 4.05500(10), c = 43.5821(7) Å, β = 108.740(2)°, V = 6257.5(2) Å3, Z = 2. The structure of neyite is based upon three different modules of archetypal PbS structure: (111)PbS slabs of octahedra extended along b alternate with (100)PbS slabs in a direction. Resulting layers are alternated with (922) PbS layers along c. The main structural feature of neyite from Yugo-Konevo deposit that distinguishes it from previously published data on neyite from type locality and cuproneyite is the disorder of Me16 site and the presence of the additional Cu5 site. These features, combined with the bond valence sums analysis, suggest the presence of chains of CuS4 tetrahedra alternating with chains of BiS6 octahedra.
