 Abstract    The new compounds A4[Nb6Cli2(N3)6](H:0)2 (A = Rb, Cs) were synthesized from In4[Nb6Cli2Cl6] by substituting six terminal Cl ligands and the In+ ions in methano-lic solution. An X-ray structure refinement was performed on single-crystal data of Rb4[Nb6Cli2(N3)6](H?0)2 (1) (space group Pi, Z = 1, a = 912.5(1) pm, b = 937.2(1) pm, c = 1062.0(1) pm, a = 96.88(2)°, ß = 101.89(1)°, 7 = 101.44(2)°) and Cs4[Nb6Cli2(N3)6](H20)2 (2) (space group PI, Z = 1, a = 920.9(5) pm, b = 947.9(7) pm, c = 1091.8(7) pm, a = 96.89(6)°,/?= 103.35(5)°, 7 = 101.60(5)°. Each of the centrosymmetric [Nb6Cli2(N3)6]4~ ions of the isotypic compounds contains six terminal azide groups at the corners of the octahedral niobium cluster (dfvj^N = 226(1) pm (1), 225(1) pm (2), bond angles Nb-N-N 120-127°). The [Nb6Cli2(N3)6]4_ ions are linked via Rb-N and Rb-Cl interactions of the Rb+ ions to form a three-dimensional structure. Crystals of the compounds react explosively on heating or mechanical pressure. Die Synthese und Struktur von Clusteraziden:
