Disordered materials with resilient and soft-templated functional units bear the
potential to fill the pipeline of robust catalysts for renewable energy storage.
However, for novel materials lacking long-range order, the ability to discern
local structure with atomic resolution still pushes the boundaries of current
analytical and modeling approaches. We introduce a two-pillar strategy to
monitor the formation and unravel the structure of the first disordered onedimensional cobalt coordination polymer catalyst, Co-dppeO2. This target
material excels through proven high performance in commercial alkaline
electrolyzers and organic transformations. We demonstrate that the key architecture behind this activity is the unconventional embedding of hydrated
{H2O-Co2(OH)2-OH2} edge-site motifs, nested into a flexible organic matrix of
highly oxidized and bridging hydrophobic dppeO2 ligands. Our combination
of in situ spectroscopy and computational modeling of X-ray scattering and
abs...orption spectra, backed with complementary experimental techniques,
holds the key to understanding the atomic-range structure of important
disordered materials.
