The Cluster Azides M 2 [Nb 6 Cl 12 (N 3 ) 6 ]·(H 2 O) 4—x (M = Ca, Sr, Ba) The isotypic cluster compounds M 2 [Nb 6 Cl 12 (N 3 ) 6 ] · (H 2 O) 4—x (M = Ca (1) , M = Sr (2) and M = Ba (3) ) have been synthesized by the reaction of an aequeous solution of Nb 6 Cl 14 with M(N 3 ) 2 . 1 , 2 and 3 crystallize in the space group Fd3¯ (No. 227) with the lattice constants a = 1990.03(23), 2015.60(12) and 2043, 64(11) pm, respectively. All compounds contain isolated 16e — clusters whose terminal positions are all occupied by orientationally disordered azide ligands.
