Nanoporous metal foams are prepared by ignition of high nitrogen transition metal complexes. The ammonium salts of iron(III) tris[bi(tetrazolato)-amine], cobalt(III) tris(bi(tetrazolato)amine), and high nitrogen compounds of copper and silver were prepared as loose powders, pressed into pellets and wafers, and ignited under an inert atmosphere to form nanoporous metal foam monoliths having very high surface area and very low density.

What is claimed is: 1. A method for preparing a nanoporous metal foam monolith comprising: forming a pressed structure of a high nitrogen transition metal complex of the formula wherein A is selected from ammonium, hydrazinium, guanidinium, aminoguanidinium, diaminoguanidinium, and triaminoguan
What is claimed is: 1. A method for preparing a nanoporous metal foam monolith comprising: forming a pressed structure of a high nitrogen transition metal complex of the formula wherein A is selected from ammonium, hydrazinium, guanidinium, aminoguanidinium, diaminoguanidinium, and triaminoguanidinium; wherein x is zero or an integer from 1 to 3, wherein y is an integer from 1 to 3; wherein z is 0 or 1, wherein L is amine; wherein q is 0 or 2; and wherein M is a transition metal; and igniting the pressed structure under an inert atmosphere. 2. The method of claim 1, wherein the transition metal complex comprises metal selected from the group consisting of titanium, vanadium, chromium, iron, cobalt, nickel, and copper. 3. Monolithic nanoporous metal foam prepared by forming a pressed structure of a high nitrogen transition metal complex of the formula wherein A is selected from ammonium, hydrazinium, guanidinium, aminoguanidinium, diaminoguanidinium, and triaminoguanidinium; wherein x is zero or an integer from 1 to 3, wherein y is an integer from 1 to 3; wherein z is 0 or 1, wherein L is amine; wherein q is 0 or 2; and wherein M is a transition metal; and igniting the pressed structure under an inert atmosphere. 4. The metal foam of claim 3, wherein said foam comprises metal selected from the group consisting of titanium, vanadium, chromium, iron, cobalt, nickel, and copper. 5. Monolithic nanoporous metal foam comprising a surface area of from about 17 m2/g to about 260 m2/g. 6. The foam of claim 5, wherein said foam comprises at least one transition metal. 7. The foam of claim 5, wherein said foam comprises a metal selected from the group consisting of titanium, vanadium, chromium, iron, cobalt, nickel, capper, and mixtures thereof. 8. The foam of claim 7, wherein said foam further comprises carbon, nitrogen, hydrogen, oxygen, or mixtures thereof. 9. A chemical compound having the formula wherein A is selected from ammonium, hydrazinium, guanidinium, aminoguanidinium, diaminoguanidinium, arid triaminoguanidinium: wherein x is zero or an integer from 1 to 3, wherein y is an integer from 1 to 3; wherein z is 0 or 1, wherein L is amine; wherein q is 0 or 2; wherein M is a transition metal, with the caveat that when z is 0, the transition metal is not copper. 10. The compound of claim 9 wherein the transition metal is selected from the group consisting of titanium, vanadium, chromium, iron, cobalt, nickel, and copper, with the caveat that when z is 0, the transition metal is not copper.
