Gas generant complex oxidizers
First Claim
1. A gas generant composition, hydrated or anhydrous, useful for inflating an automotive air bag passive restraint system, comprising a nonazide fuel and a coordination complex oxidizer, whereinsaid nonazide fuel is selected from the group consisting of urazoles, tetrazoles, triazoles, triazines, and derivatives of guanidine, andsaid coordination complex oxidizer comprises an inorganic compound having a polynitro transition metal complex anion, said coordination complex oxidizer being selected from the group consisting of disodium potassium hexanitrocobaltate (III), dipotassium barium hexanitrocobaltate (II), dipotassium sodium hexanitrocobaltate (III), and dipotassium strontium hexanitrocobaltate (II).

Abstract
Nonazide gas generant compositions, useful for inflating passenger restraint gas inflator bags, comprise a multimetallic coordination complex oxidizer selected from coordination complexes comprised of anionic nitro and nitrito ligands coordinated with a transitional metal template, and a cationic component comprised of two or more different metals. The gas generant compositions generate relatively more gas and are significantly less toxic than known azide gas generant compositions, and furthermore, generate solids that are readily filterable.
