WARNING: The published thermal displacement parameters have been converted to
U,s. The calculated standard uncertainties (s.u.) have been based uniquely on
the published ones without considering the s.u. of any other quantity involved
in such conversion.

WARNING: The published thermal displacement parameters, Biso, have been
converted to Uiso.
