Dipyridiniomethane cis- and trans-Difluorotetrachloroosmate(IV), cis- and trans-[(C₅H₅N)₂CH₂][OsCl₄F₂]

In the structures of N,N'-methylenedipyridinium cis-difluorotetrachloroosmate(IV), (I), and N,N'-methylenedipyridinium trans-difluorotetrachloroosmate(IV), (II), cis- and trans-[(C₅H₅N)₂CH₂][OsCl₄F₂], the trans influence in the F-Os-Cl axes of (I) lengthens the average Os-F distance to 1.948 Å and shortens the average Os-Cl distance to 2.316 Å, compared with those of the symmetrically coordinated axes F-Os-F in (II) and Cl-Os-Cl in (I) and (II), respectively, with mean values of 1.926 and 2.337 Å observed for Os-F and Os-Cl, respectively.
