#Calcium Sulfate Hydrate (Bassanite), CaS04-0.5H20
#Pseudo-orthorhombic, I***, Z = 12. The literature on CaS04-0.5H20 is extensive and
#confusing as noted by Gay [1965] and Clifton [1972]. The cell below was modified from
#one given by Gay [1965] who stated that the true symmetry was monoclinic, with p = 90 .
#This NBS cell was also consistent with one found by use of the Visser program and
#associated refinement procedures. Bushuev [1980] reported a similar monoclinic cell
#for CaS0 4 -0.67H 2 0 with a=12.028, b=38.022, c=6.927, Y=90.21 , space group 12. There
#was no evidence to require the monoclinic cell for NBS data.
#Lattice constants of this sample
#a = 12.031(4), b = 12.695(6), c = 6.934(2)
#a/b = 0.9477, c/b = 0.5462
