| [Er14(C2)2 (N )2 ] l24 -ein Iodid mit einem oligom eren, heterointerstitiellen Cluster [E r14(C2)2(N)2]l24 -an Iodide with an Oligomeric, H eterointerstitial Cluster  | | | | Abstract
| [Er14(C2)2(N)2]l24 (triclinic, P I, a = 966.3(4) pm. b = 1027.6(2) pm. c = 1663.4(4) pm, « = 101.374(9)°, ß = 92.853(14)°, y = 112.83(2)°, Z = 2) is obtained as red-brown single crystals through a conproportionation reaction of E rl3 and erbium in the presence of carbon and N aN 3 in a sealed niobium container. It contains discrete, tetrameric [Er14(C2)2(N)2] clusters that are built from two octahedra and two tetrahedra connected via com mon edges. The octahedral voids are filled with C2 units and the tetrahedral voids with N atoms. Each discrete [Erj4(C2)2(N)2] cluster is surroun ded by 32 iodide ligands which connect six clu sters via i-a and a-a bridges. | | | |
