Figure 3
(a) Selectively labelled view of an inversion-related cation pair (i.e. dimer) perpendicular to the nine-atom mean plane of the upper cation defined by the pyridine ring, the imine N and C atoms, and the PtII ion. Using the Pt—Cl bond vectors to define the relative orientations of the cations, the geometry of the dimer is best described as an offset head-to-head π-stacked pair. (b) An edge-on view of the dimer down the Cl—Pt bond vector of the upper cation. The Pt⋯Pt distance and MPS are indicated. The trigonometric relationships involving the PtII ions are shown on the triangle below the dimer. MMPD is the metal-to-metal perpendicular distance. Because the PtII ions are displaced above and below the nine-atom mean plane of the top and bottom cations by 0.039 Å, respectively, the MMPD is not equivalent to the MPS. The LS is calculated using Pythagoras' theorem from the MMPD and Pt⋯Pt ion separation. [Symmetry code: (v) −x + 1, −y, −z + 2.] |
