 The space group, lattice parameters and the atomic coordinates have been
 changed due to the structure being originally uploaded in a different space
 group setting than the one described in the original publication ("-P 2ybc"
 instead of "-P 2yn"). Some additional pieces of information like the R factor
 and the anisotropic parameter values have also been added.
