Crystallography of Childrenite

Crystal System:Orthorhombic
Class (H-M):mm2 - Pyramidal
Space Group:Ccc2
Cell Parameters:a = 10.41Å, b = 13.42Å, c = 6.92Å
α = 90°, β = 90°, γ = 90°
Ratio:a:b:c = 0.776 : 1 : 0.516
Unit Cell Volume:V 966.74 ų (Calculated from Unit Cell)
Morphology:Equant to pyramidal crystals, short prismatic [001], tabular, platy, radiating groups, fibrous crusts, massive.
Twinning:Common. May show on {100} and {001}. Twins evident when of varying proportions but symmetrical twins consist of four to eight individuals in sectors with four individuals comprising a "termination". Visible twinning is uncommon.
Comment:Bba2; possibly monoclinic pseudo-orthorhombic.
