Abstract: | Cs3Tb10(C2)2]Cl21, A New Formula and Structure Type with Isolated Dimeric Clusters Cs3Tb10(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; β = 98.13(6)°; R = 0.089; Rw = 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. |
