An Organically Templated Cobalt Germanate
An open-framework cobalt germanate of the formula, [Co2(NH2(CH2)2NH2)3][Ge9O18(OH)4] has been prepared under solvo/hydrothermal conditions in the presence of ethylenediamine. The germanate is constructed by Ge9O18 clusters and contains eight- and ten-membered channels. Besides connecting two Co sites, the amine also acts as a bis-chelating agent and protrudes into the eight-membered channel.
