Structure and properties of a ferrocenylpyrimidine–bromanilic acid hydrogen-bonded supramolecular complex

A hydrogen-bonded assembly composed of ferrocenylpyrimidine (FcPM) and bromanilic acid (BA), represented as [FcPM](BA)(acetone)0.5, was prepared and crystallographically characterized. The asymmetric unit of the crystal contained two crystallographically independent molecules of FcPM and BA, which were alternately connected to form one-dimensional zigzag chains via OH ⋯ N hydrogen bonds. The BA molecules were stacked to form one-dimensional columns. No charge transfer was observed between FcPM and BA. Acetone molecules, which were located in channels, were desorbed at 433 K.
