WebMar 23, 2024 · Bonjour. La méthode générale consiste à superposer le diagramme potentiel-pH du bismuth au diagramme potentiel pH correspondant au couple NO3-/NO. On peut prévoir une réaction quasi totale entre un oxydant du second diagramme et un réducteur du premier diagramme si leurs domaine de prédominance ou d'existence sont … WebNb3(BiS3)2 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. Nb2+ is bonded to six S2- atoms to form distorted edge-sharing NbS6 pentagonal pyramids. There are two shorter (2.48 Å) and four longer (2.49 Å) Nb–S bond lengths. Bi3+ is bonded in a linear geometry to two equivalent S2- atoms. Both Bi–S …
