1,4‐Di‐4‐pyridylpiperazine 1 was prepared from reaction of piperazine with 4‐chloropyridine and then further blended with p ‐alkoxybenzoic acids. Subsequently, a series of H‐bonded complexes were obtained and the mesogenic behaviours of the complexes were then investigated. A good quality of crystal from 1,4‐di‐4‐pyridylpiperazine and p ‐octyloxybenzoic acid for single crystal structure determination was also isolated and then studied.
