29. Crystal data were measured on a Gemini Oxford diffractometer using CuKα radiation (λ = 1. 54184 A) at 150(2) K. Owing to the instability of the CoIII oxidation state in the oxidized frameworks CoIIISi and CoIIIGe, without the persistent presence of oxidizing agent, it was not possible to collect full and accurate elemental analysis on these materials. Consequently, the reported crystallographic formulae have been estimated based on the original formulae, 3a and 4a, combined with the charge balance required for these oxidized frameworks. CCDC 666405 (3a), 666406 (4a), 783645 (3b), and 783646 (4b) contain the supplementary crystallographic data for this paper.
