CompoundCu2 Si2 Tm1 - Copper thulium silicide (2/1/2) [NO2P2] [tI10] [e d a] [CeAl2Ga2]
Cell3.9250(8), 3.925, 9.9922(12), 90., 90., 90.
I4/MMM (139) V=153.94
RemarksR=0.041000 : NDP PDF =65-4636 : TEM =300 : TYP =CeAl2Ga2 :
Calculated density unusual but tolerable.
At least one temperature factor missing in the paper.
The coordinates are those given in the paper but the atomic distances do not agree with those calculated during testing.The coordinates are probably correct.
