Crystallography of Gramaccioliite-(Y)Hide

Crystal System:
Trigonal
Class (H-M):
3 - Rhombohedral
Cell Parameters:
a = 10.411(3) Å, c = 20.97(3) Å
Ratio:
a:c = 1 : 2.014
Unit Cell V:
1,968.40 ų (Calculated from Unit Cell)
Morphology:
Six-sided tabular crystals (rhombohedral-pseudohexagonal), often with a strongly corroded appearance.
Comment:
Cell refined from powder data; single-crystal data gave smaller parameters, a = 10.383, c = 20.882 Å (Orlandi et al., 1994). REE-rich material from Samos island has a = 9.1814(5) Å and α = 68.820(4)° (hexagonal setting: a = 10.377, c = 20.872 Å) (Theye et al., 2010).
