The combined atomic and molecular layer deposition (ALD/MLD) technique offers a unique way to build—both known and previously unknown—crystalline coordination polymer materials directly from gaseous precursors in a high‐quality thin‐film form. Here, we demonstrate the ALD/MLD of crystalline Li‐, Na‐, and K‐based 3,5‐pyridinedicarboxylate (3,5‐PDC) thin films; the Li 2 ‐3,5‐PDC films are of the known Li‐ULMOF‐4 crystal structure whereas the other as‐deposited crystalline films possess structures not previously reported. Another exciting possibility offered by ALD/MLD is the deposition of well‐defined but amorphous metal–organic thin films, such as our Mg‐, Ca‐, Sr‐, and Ba‐based 3,5‐PDC films, which can then be crystallized into water‐containing structures through a post‐deposition humidity treatment. All together, the new metal–organic structures realized in this study through ALD/MLD comprise a majority of the (anhydrous and water‐containing) members of the s‐block metal 3,5‐pyridinedicarboxylate family.
