Abstract:
An open-framework cobalt germanate of the formula, [Co-2(NH2(CH2)(2)NH2)(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. (C) 2002 Elsevier Science (USA). All rights reserved.
