Figure 1
(a) A view of the asymmetric unit and some symmetry-related atoms of Ca₂GeO₄, showing 95% probability displacement ellipsoids and the atomic nomenclature scheme [symmetry codes: (i) x, $[1\over2]$ − y, z; (ii) − $[1\over 2]$ + x, $[1\over2]$ − y, $[1\over2]$ − z; (iii) $[1\over2]$ − x, $[1\over2]$ + y, $[1\over2]$ + z; (iv) $[1\over2]$ − x, −y, $[1\over2]$ + z; (v) x, y, 1 + z; (vi) 1 − x, − $[1\over2]$ + y, 1 − z; (vii) 1 − x, −y, 1 − z; (viii) 1 − x, − $[1\over2]$ + y, −z]. (b) A full polyhedral representation of the olivine structure.
