Bond-valence model for metal cluster compounds. I. Common lattice strains

The bond-valence model used previously only for common ionic solids was adapted to (TM)₆-chalcohalides, M_x(TM)₆L_y (TM = transition metal in the cluster: Nb, Mo, W and Re; L = chalcogen and/or halogen ligands; M = counter-cation). This paper is devoted to the strains around M cations as one of the sources of the valence violations in cluster compounds.

Bond-valence model for metal cluster compounds. II. Matrix effect

The bond-valence model used previously only for common ionic solids was adapted to (TM)₆-chalcohalides, M_x(TM)₆L_y (TM = transition metal in the cluster: Nb, Mo, W and Re; L = the chalcogen and/or halogen ligands; M = counter-cation). This paper gives a detailed description of the matrix effect.
