摘要：

The structure of dipyridiniomethane cis-dichlorotetrafluoroosmate(IV) {or N,N-methylenedipyridinium dichlorotetrafluoroosmate(IV), cis-[(C5H5N)2CH2]-[OsF4Cl2]}, has been determined by single-crystal X-ray diffraction at room temperature. The complex anions are completely ordered in the lattice. As a result of the trans influence in the two asymmetric axes Cl-Os-F, the Os-F distances of 1.941 (4) and 1.953 (5) angstrom are slightly lengthened compared to those of the symmetric F-Os-F axis of 1.931 (5) and 1.934 (4) angstrom. Correspondingly, the Os-Cl distances of 2.324 (2) and 2.335 (2) angstrom are shortened in comparison with those of 2.364 angstrom in the octahedral complex anion of K2[OsCl6].
