Multicomponent host–guest complexes consisting of 1,3-adamantanedicarboxylic acid (1) and 4,7-phenanthroline (phen) as the host moiety with different guests are prepared through co-crystallization. Detailed structural analysis of the obtained complexes, characterized by the single-crystal X-ray diffraction method, has been reported. In all the complexes, molecules of 1 and phen constitute a unique four-membered cyclic host network into a two-dimensional arrangement. Further stacking of such networks resulted in a channel structure directed by the guest species through O–H···O hydrogen bonds.
