PLAT043

 Note: atomic weights used in the calculation of the molecular weight are   
 taken from Inorg. Chim. Acta 217 (1994) 217-218 which deviate in a few cases   
 slightly from the older values used in SHELXL97-2. 
 NOTE: The tabulated atomic weights that are used may deviate from the actual
 value in case of special isotopes of e.g. Uranium or Plutonium.
