 Compound was prepared by reaction of 1,2,7-isomer of
 Re2Cl5(PMe3)4 with nitrosonium hexafluorophosphate in
 the presence of butylammonium chloride in dichloromethane
 solution at room temperature. Single crystals were obtained
 by slow diffusion of isomeric hexanes into dichloromethane
 solution.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo^2^)+(0.0052P)^2^+6.7806P] 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^)+(0.0052P)^2^+6.7806P] where P=(Fo^2^+2Fc^2^)/3'.
