摘要：

Cs[Tb10(C2)2]Cl21 is obtained via the metallothermic reduction of TbCl3 with caesium in the presence of graphite as black single crystals. The crystal structure (monoclinic, C2/c, Z = 4; a = 2318.72(13); b = 1245.8(9); c = 1502.0(13) pm; beta = 98.13(6)-degrees; R = 0.089; R(w) = 0.049) contains dimeric clusters that are built from two octahedra connected via one common edge and filled with C2 units. These isolated [Tb10(C2)2] clusters are surrounded by 26 chloride ligands which are then connected via i-a and a-a bridges in a way that voids for Cs+ of coordination number 10 are formed.
