Golden Remark: "If you assume formula and Pearson Symbol (along with the Space-group number) together are sufficient to identify a structure, then there is a 488 in 53766 (0.9%) probability that you are wrong. And that probability is more than enough to spoil the fun."
Been there, experienced it first hand yesterday.
Moral of the story : If you happen to be involved with any of the following beauties, just make sure that their twins aren’t swapping with your sweetheart. Otherwise, it is very likely that you’ll get your heart broken into two (actually into three for the ones marked with *). Checking their height-width-and shoe number works well (or directly check the volume, so to speak…)
