Problem with occupancy exceeding 1.
Occupancy corrected using following rules:
- Fe/Mn and Li relatives occupancies as refined by authors
- Fe/Mn ratio fixed to nominal composition: 0.75/0.25, 0.5/0.5, 0.25/0.75
- O and P occupancies = 1
Everything turn out correct this way.

#----------------------------------------------------------------------

The original ko5132.cif from the IUCr web-site was updated according
to the message received from the authors:

From:  Bo Brummerstedt Iversen <bo@xxxxxxxxxxxxxxxxx>
To:    Saulius Gra\<ulis <grazulis@xxxxxxxxxxxxxxx>
Subject:        Re: Supplementary data for your paper ko5132.cif
Date:           Thu, 12 May 2011 10:27:02 +0200 (11:27 EEST)

Dear Saulius,

Thanks for your mail

1) /.../ The compositions are LiFePO4, LiFe0.75Mn0.25PO4,
LiFe0.50Mn0.50PO4, and LiFe0.25Mn0.50PO4

The occupancy of the Fe in the second block should therefore be
changed to 0.7465(17), while that of manganese should be 0.25096. We
are sorry about this confusion.

2) Yes, the bruttoformula should be the data header, and the Z value 4

3) Yes, the data were measured at 345 degrees celcius.

4) Yes, the pressure during the measurement was 250 bar.
/.../

Best regards,
Bo

Changed an atom site label from '0.0000' to 'P1' for consistency and
readability.
