DATASET 1 : space group Cm m 2 (# 35); Bravais oC (1-face-center ortho.)
l want to know the structure parameters of rhombohedral phase PZT or others perovskite structure.
Thanks a lot.

The Bravais lattice determined only from the primitive
vectors, bravais(1)= 6, is more symmetric
than the real one, iholohedry= 3, obtained by taking into
account the atomic positions. Start deforming the primitive vector set.

symlatt : the Bravais lattice is oC (one-face-centered orthorhombic)
symspgr : spgroup= 35 Cm m 2 (=C2v^11)
How to understand it?
