Abstract
The manganese complex of the invention is one represented by the formula (1 ) EQU [Mn(H.sub.2 NNHCONH.sub.2).sub.3 ](NO.sub.3).sub.2 (1) and showing weight loss of not higher than 1% after heating at 107.degree. C. for 400 hours. The manganese complex has high heat stability and is used as an active component of an air bag gas generating composition. The air bag gas generating composition of the invention contains the above-mentioned manganese complex. The air bag gas generating composition comprising a complex mixture of the manganese complex and magnesium complex of semicarbazide and/or carbohydrazide features a high rate of combustion residue in an inflator.
