Abstract
Rubidium dibarium penta-azide, RbBa2(N-3)(5), was prepared from an
aqueous solution of the binary azides at room temperature. It
crystallizes in the monoclinic system (space group P2/n). Two central
atoms of azide groups occupy the 2c ((1) over bar) and 2b ((1) over
bar) positions, another azide group lies completely on a twofold axis
(2f), while Rb atoms are situated in 2e (2) positions. The crystal
structure of RbBa2(N-3)(5) can be regarded as a distorted AlB2-type
arrangement of the metal atoms, with the azide groups occupying the
voids between the cations. This results in coordination numbers of 8
(Rb) and 10 (Ba). The N-N distances are in the range 1.169 (8)-1.190
(5) angstrom, typical for the azide group.
