Figure 3. Structures of bis-(β-carotene) Pd10 chain complexes.

Figure 3

(a) Thermal ellipsoid (50%) drawing of meso-[Pd10(μ10-β-carotene)2][B(ArF)4]2 (1-meso). (b) Ball-stick drawing of 1-meso. (c) Thermal ellipsoid (30%) drawing of rac-[Pd10(μ10-β-carotene)2][B(ArF)4]2 (1-rac). (d) Ball-stick drawing of 1-rac. (e) C–C bond lengths in 1-meso and free β-carotene (CCDC-253816), determined by X-ray structural analyses. (f) A view of a part of an intermolecular backbone π–π stacking column of 1-meso in the crystalline state. (g) A side view of a part of the π–π stacking column of 1-meso. For a–d,f,g, B(ArF)4 anions and non-coordinating solvent molecules were omitted for clarity.
