Abstract

Disclosed herein is a novel class of halide-based framework solids based on a Zn.sub.n Cl.sub.2n parentage, as zeo-types are related to Si.sub.n O.sub.2n. These materials, referred to as halo zeo-type materials, constructed from Lewis acidic and redox active tetrahedral building blocks, should augment the size and shape selectivity characteristics of zeolites. One example of these materials, compound CZX-1, has the formula ?NH(CH.sub.3).sub.3 !CuZn.sub.5 Cl.sub.12. Another example of these materials, compound CZX-2, has the formula ?NH.sub.2 (CH.sub.2 CH.sub.3).sub.2 !CuZn.sub.5 Cl.sub.12. Compound CZX-3 has the formula ?H.sub.2 N(CH.sub.3).sub.2 !.sub.n ?Cu.sub.n Zn.sub.6-n Cl.sub.12 !, wherein n may be 1 or 2. Compound CZX-4 has the formula ?A!.sub.n ?Cu.sub.2 Zn.sub.2 Cl.sub.7 !, wherein A may be H.sub.3 NCH.sub.3.sup.+ or Rb.sup.+. The invention also relates to colloidal suspensions which may utilize the halide-based compounds.
