Gas generating compositions and methods for their use are provided. Metal complexes are used as gas generating compositions. These complexes are comprised of a cationic metal template, sufficient oxidizing anion to balance the charge of the complex, and a neutral ligand containing hydrogen and nitrogen. The complexes are formulated such that when the complex combusts nitrogen gas and water vapor is produced. Specific examples of such complexes include metal nitrite ammine, metal nitrate ammine, and metal perchlorate ammine complexes, as well as hydrazine complexes. Such complexes are adaptable for use in gas generating devices such as automobile air bags.

A method for inflating an inflatable air bag which comprises the steps of: generating substantially non-toxic gas consisting essentially of nitrogen gas and water vapor by combusting an at least essentially azide-free composition adapted for generating gas for use in inflating an air bag which comprises a metal ammine complex having a metal cation of a transition metal or an alkaline earth metal, sufficient oxidizing anion to balance the charge of the complex, and a neutral ligand comprising ammonia; and inflating said air bag using said gas.
