Commensurate monoclinic form of Ca(2)Zn(0.97)Co(0.03)Ge(2)O(7).

Abstract

Cobalt-doped dicalcium zinc germanate, synthesized by slow cooling from the melt, is monoclinic and has a layered structure, which is different from the modulated melilite-type structure of Ca(2)ZnGe(2)O(7). The monoclinic form has two different Ca, one Zn and two Ge sites, and seven independent O-atom positions; all are in general position 4e of the space… (More)
