Gas generating compositions and methods for their use are provided. Metal complexes are used as gas generating compositions. These complexes are comprised of a metal cation template, a neutral ligand containing hydrogen and nitrogen, sufficient oxidizing anion to balance the charge of the complex, and at least one cool burning organic nitrogen-containing compound. 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. A binder and co-oxidizer can be combined with the metal complexes to improve crush strength of the gas generating compositions and to permit efficient combustion of the binder. Such gas generating compositions are adaptable for use in gas generating devices such as automobile air bags.

[ What is claimed is:] [1.]1. A method of inflating an air bag comprising combusting a gas generating composition containing a complex of a transition metal cation or alkaline earth metal cation, at least one neutral ligand containing hydrogen and nitrogen, and sufficient oxidizing anion to balance the charge of the metal cation, such that when the gas generating composition combusts, a mixture of gases containing nitrogen gas and water vapor is produced, wherein the composition further contains at least one cool burning organic nitrogen-containing compound.
