Octadecabromidobis(dicarbido)decadysprosium, [Dy₁₀Br₁₈(C₂)₂]

K. Daub and G. Meyer

Abstract: Single crystals of [Dy₁₀Br₁₈(C₂)₂] were obtained during the reaction of DyBr₃ with dysprosium metal and graphite in a sealed tantalum container. In the crystal structure, the Dy atoms form dimers of edge-sharing octahedra, each encapsulating a C₂ unit. The metal atoms are surrounded by Br atoms above the cluster edges and vertices, respectively. The dimers are connected to each other by Br atoms, leading to a three-dimensional network. [Dy₁₀Br₁₈(C₂)₂] is isotypic with its iodido analogue [Dy₁₀I₁₈(C₂)₂].
