  • Metallochalcogenide microporous compositions having metal-metal bonds
    Patent number: 5830427
    Abstract: This invention relates to dimetal sulfide or selenide microporous crystalline compositions. These compositions have the empirical formulaR.sub.x (M.sup.1+.sub.y M.sup.2+.sub.z M.sub.4)A.sub.qwhere R is a cation such as tetramethylammonium ion, M.sup.1+ is a metal such as copper, silver, etc. M.sup.2+ is a metal such as zinc, cobalt, etc., M is germanium or tin and A is sulfur or selenium. The subscripts x, y, z and q represent the mole fractions of R, M.sup.1+, M.sup.2+ and A respectively. Finally, the three dimensional structure of said composition is characterized in that it contains M.sup.1+ --M.sup.1+ metal-metal bonds.
