We report that natrolite, Na{sub 16}Al{sub 16}Si{sub 24}O{sub 48} {center_dot} 16H{sub 2}O, a small pore auxetic zeolite can incorporate significant amounts of Argon under moderate pressure- and temperature conditions resulting in Na{sub 16}Al{sub 16}Si{sub 24}O{sub 80} {center_dot} 16H{sub 2}O {center_dot} 6Ar. This material has a {approx}6.5% larger unit cell than natrolite at ambient conditions and its structure is related to Na{sub 16}Al{sub 16}Si{sub 24}O{sub 80} {center_dot} 24H{sub 2}O, an intermediate superhydrated natrolite referred to as para-natrolite. Argon insertion under pressure into auxetic frameworks such as natrolites is an important and overlooked confinement mechanism with potential applications and implications.
