Silver nitrate in silver zeolite A: three-dimensional incommensurate guest ordering in a zeolite framework†
Abstract
We report the results of a detailed examination of the occlusion of m) remained largely unaffected by the guest in this compound, which was found to exhibit strong negative thermal expansion. The host and guest lattices are incommensurate with the tetragonal guest lattice being slightly larger than the cubic host in the c-direction and slightly smaller in the a- and b-directions.
