The structures of nickel sulfoselenide Chevrel phases have been determined. All the richest nickel phases crystallize in rhombohedral symmetry. A single-crystal structural study makes it possible to identify the special nickel cation locations inside

Three different types of pseudo-binary Mo 6 Se 8−x S x Chevrel phases series have been reported in the literature. Confusion among them has existed, although two of them are metastable series. We present a new study of these series, based on their

The replacement of a small amount of chlorine by fluorine has made it possible to synthesize Nb6Cl15 − xFxin chlorofluoride with the Ta6Cl15 structure-type. The crystal structures of two compositions in the solid solution (x = 2.2 (I) and x = 4.4 (

A trivalent cluster unit has been synthesized by the solid-state route for the first time in the Rb–Re–S–Br system. The new rhombohedral compound Rb3Re6S7Br7 is built from octahedral Re6 clusters surrounded by two μ3-Si and six μ3-Li ligands

In this paper, we present a comparative electrochemical study of copper insertion into series of Mo 6 Se 8− x S x phases which are obtained through different synthesis processes. We show that α -, β -, and HT-forms can reversibly accommodate copp

In the literature Mo6Se8−xSx (0≤x≤4) Chevrel phase binaries are stable compounds, synthesized by solid state reaction from stoichiometric mixture of MoS2, MoSe2, and Mo powders at 1200°C. We report the single-crystal structure of these compoun

The grain surfaces of PbMo 6 S 8 , (Pb,Sn)Mo 6 S 8 , and SnMo 6 S 8 high magnetic field Chevrel-phase superconductors have been investigated by high-resolution electron microscopy. Our investigations have shown that the grain surface of PbMo 6 S 8 ex
