An opening for CO : An iron PNP pincer complex self‐assembles in the solid state through intermolecular FeCl⋅⋅⋅HN hydrogen bonds to form a 3D supramolecular network. This compound reacts readily with gaseous CO in the solid state and in solution to stereospecifically give the octahedral complexes cis ‐ and trans ‐[Fe(PNP‐ i Pr)(CO)(Cl) 2 ], respectively. In the solid‐state process the supramolecular connectivities between individual molecules are maintained without loss of crystallinity.
