5-triazinyl (DAT) groups are known to form N–H···N hydrogen bonds according to reliable patterns of self-association. In compounds 3a–c, three DAT groups are attached to trigonally substituted phenyl cores via identical flexible arms. Crystallization of compounds 3a–c produces robust networks in which each molecule is linked to its immediate neighbors by a total of 10–12 hydrogen bonds. In compound 3a, the DAT

self-assembly of podands. The crystalstructures of the halophenyl-functionalized podands (P2, P3, and P4) showed self-assembly primarily via intermolecular C–H⋯O, C–H⋯π, and halogenbonding interactions. Hirshfeld surface analysis of the crystalstructures revealed significantly higher contributions from H⋯C and H⋯X (X = halogen) close contacts in comparison to H⋯O and X⋯C close contacts in 2D-fingerprint plots
