| Description | Another new compound, octacalcium pentagermanium
octadecaoxide Ca8Ge5O18, represents a new intermediate
phase between CaO and GeO2, and had not
previously been reported in the literature. The structure
consists of three different Ge sites, two of them on
general 8d positions, site symmetry 1, one on special
position 4d, site symmetry 2. Three of the five Ca sites
occur on 8d positions, site symmetry 1, one Ca is on 4b
with site symmetry and one Ca is on 4c with site
symmetry 2. All nine O atoms have symmetry 1 (8d
position). By sharing common edges, the Ca sites
form infinite bands parallel to the c axis. These bands
are interconnected by isolated GeO4 and Ge3O10 units.The (100) layers are stacked along a in an ABAB...
sequence, with the B layer being inverted and displaced
along b/2. |
