First Open-Framework Zinc Germanates by a Molecular Templating Route
Source abstract
Abstract
Despite the recent progress in the synthesis of new germanates, no zinc germanate has been synthesized by using a molecular templating route. A unique type of zincogermanate framework has now been prepared by using ethylenediamine as the structure-directing agent. The three-dimensional framework can be simply described as the face-centered packing of an elongated neutral cluster unit, Ge9O18.
