Using scanning tunneling microscopy, we resolve the self-assembled formation of highly ordered bilayer structures of Fe atoms and organic linker molecules (T4PT) when deposited on a Au(111) surface. The Fe atoms are encaged in a three-dimensional coordination motif by three T4PT molecules in the surface plane and an additional T4PT unit on top. Within this crystal field, the Fe atoms retain a magnetic ground state wi","authors_text":"A. Kr\\\"uger, C. F. Hermanns, I. Fernandez-Torrente, J. I. Pascual, K. J. Franke, M. Bernien, P. Stoll, T.
