Double halogen bridges

The vapor36 (and probably the CC14 solution) contains U2C110 molecules that probably have octahedral Uv with a double halogen bridge. In the crystal...

Figure 18 schematically displays parts of CPK packing model for [Pt(en)2][PtCl2(en)2](20)4 in the yz plane (direction of coordination) and in the jny plane, respectively [95]. A minimum distance between aligned anionic head groups of double-chained amphiphiles is estimated as 5 A from CPK molecular model, and this value matches well with the Pt -Cl-Pt distance d) in the onedimensional complex. Therefore, it is reasonable that the halogen-bridged mixed-valence complex can be well preserved in polyion complexes.
