Figure 3
A fragment of the one-dimensional coordination polymer of (I), depicting the quadruple-stranded helical arrangement of the HADC− ligands along the chain of ThIV ions, which define the helical axis. A single ligand strand is shown with black bonds. [Symmetry codes: (vii) y, −x, z − 1; (viii) x, y, 1 + z; (ix) −y, x, 1 + z.] |
