Figure 2
The tridecametallic core of [(Cu10Ir3Cl4(IMes)3(pyrazine))2(pyrazine)]·3.18CH3OH, with displacement ellipsoids drawn at the 50% probability level. Note that only the donor atoms of the ligands attached to the polyatomic core are shown. The core is shown in two different orientations, rotated by 90° around the Ir1, Cu3, Cu4, Ir2, Ir3, Cu8, Cu9, Cu8, Cu9 plane. Atom labels marked in grey correspond to atoms hidden from view. The centrosymmetric compound contains two of these cores linked by a bridging pyrazine and therefore the two tridecametallic units are equivalent by symmetry. |
