P4/NMMZ (129) V=149.2
RemarksR=0.048000 : P =39-1225 :
Calculated density unusual but tolerable.
At least one temperature factor is implausible or meaningless but agrees with the value given in the paper.
The coordinates are those given in the paper but the atomic distances do not agree with those calculated during testing.The coordinates are probably correct.
