    摘要: This invention relates to novel crystalline molecular sieves having the pharmacosiderite structure and having germanium and M metals as framework elements. Optionally, titanium and silicon can also be a framework element. The M metals can be any metal which has octahedral coordination and has a valence of +2, +3, +4 or +5. Illustrative of these M metals are niobium, tin, antimony, aluminum, gallium and tantalum.
