Realization of molecular recognition with transition metal complexes via exploitation of CHFM and/or OHFM hydrogen bonds—this aim is approached by the result that was observed with the W II ‐complex 1 , which proves to be a surprisingly strong Lewis base that binds 4‐chlorophenol equally as well as pyridine. The solid‐state packing of an analogue of 1 fluorinated in the aryl ring is characterized by hydrogen bonds between imine‐CH and fluoroligands.
