However, current phytochemical coordination chemistry remains dominated by amorphous systems, and structurally resolved crystalline frameworks are still largely restricted to simple and symmetric molecules. This gap has hindered atom\u2010level understanding of phytochemical coordination and limited the rational development of crystalline materials from these abundant natural ligands. Here, we report SCU\u20101, the first structurally resolved crystalline coordination framework constructed from hematoxylin (HMT), a historically important but structurally complex and asymmetric phytochemical. Structural modeling, three\u2010dimensional electron diffraction (3DED), Rietveld refinement, and quantum\u2010chemical calculations together reveal that such an asymmetric phytochemical can assemble into periodic crystalline frameworks while generating coordination heterogeneity. Structural resolution further defines precise pore architectures, coordination environments, and host\u2013guest interaction sites, thereby enabling direct elucidation of structure\u2013property relationships. Importantly, SCU\u20101 exhibits exceptional robustness, strong CO\n                    <jats:sub>2<\/jats:sub>\n                    affinity, and visible\u2010light\u2010driven photocatalytic CO\n                    <jats:sub>2<\/jats:sub>\n                    conversion in water with selective ethanol production. These results establish asymmetric phytochemicals as viable building units for robust crystalline metal\u2013organic materials and demonstrate the importance of structural determinacy in advancing phytochemical coordination chemistry and structure\u2013property relationships.\n
