 All H were clearly identified in difference syntheses. The
 B-H on the open carborane face were refined "freely" (but heavily restrained
 using SADI). Other H riding.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo^2^)+(0.0303P)^2^+9.6252P] where P=(Fo^2^+2Fc^2^)/3' was
changed to 'calc'. New tag '_refine_ls_weighting_details' was
created. The value of the new tag was set to
'w=1/[\s^2^(Fo^2^)+(0.0303P)^2^+9.6252P] where P=(Fo^2^+2Fc^2^)/3'.
