Webazide, any of a class of chemical compounds containing three nitrogen atoms as a group, represented as (-N3). Azides are considered as derived from hydrazoic acid (HN3), an inorganic salt such as sodium azide (NaN3), or an organic derivative in which the hydrogen atom of hydrazoic acid is replaced by a hydrocarbon group as in alkyl or aryl azide … WebSodium azide is an ionic solid. Two crystalline forms are known, rhombohedral and hexagonal. [1] [6] Both adopt layered structures. The azide anion is very similar in each form, being centrosymmetric with N–N distances of 1.18 Å. The Na+ ion has an octahedral geometry. Each azide is linked to six Na+ centers, with three Na–N bonds to each ...
