ATOMIC COORDINATES

COMMENT:
NAMING CONVENTION (via column EXT): Al13Co4.mC32, Al13Os4.mC34 and Al3Co.oI96 may be viewed as different stackings of the same average layer with slight modifications. The layer modifications are denoted "D" for dense, "M" for medium and "L" for loose: D has 13 Al, M 12 and L 10. The mC32 structure is then "MM" stacking, mC34 "DD" stacking and oI96 is "DLDDLD". This is DLDM stacking.
