There is no FCC structure of Pt

FCC structure is very common for most metals. But, I didn’t find these structures. Why is that?

Hi @luo_rui

The only Pt structure on MP is fcc:

Hi, thanks, but the parameters are a=p=r=60 not 90. Most metals are like this as well. So, is there something wrong or I didn’t understand well?

Hi @luo_rui

This representation is the primitive lattice. To determine crystal type, it’s best to look at the spacegroup.

Thanks, @shyamd, I got it.
