Abstract Four new M3L2 molecular cages (CA1–CA4) have been synthesized in excellent yield via coordination driven self –assembly of flexible tri-imidazole donors based on triazine (L1) and tri-phenyl benzene (L2) core with 90° cis-blocked metal acceptors of Pd(II). Two of them CA1 and CA2 are highly soluble in water. All the cages were characterized by spectroscopic studies and ESI-MS; CA3 and CA4

Reaction of nanometer-sized tripodal ligand 2,4,6-tris[4-(imidazol-1-ylmethyl)phenyl]-1,3,5-triazine (timpt) with lead(II) nitrate affords a novel polycatenated structure containing three interpenetrating 4.82 networks, in which the lead(II) atom has a hemidirected coordination geometry and a stereochemically active lone pair of electrons.

Syntheses, Structures, and Properties of Two‐Dimensional Honeycomb Networks from the Assembly of the Tripodal Ligand 2,4,6‐Tris[4‐(imidazol‐1‐ylmethyl)phenyl]‐1,3,5‐triazine with Metal Salts
Research on self-assembled metallosupramolecular architectures has bloomed in recent times. Analogous metal–free organic architectures with water solubility are highly challenging. We report here a unique class of triazine based immidazolium water-soluble metal–free interlocked organic cage (1), which was synthesized in a one-pot reaction without using dynamic covalent chemistry and without any chromatographic

prepared cages of [M3(L1)2] and [M4(L2)6] in aqueous medium leads to the formation of interlocked systems and their formation was monitored by time dependent 1H NMR. Self-recognition of L1 by [M6(L2)4] or L2 by [M3(L1)2] leads to the formation of interlocked system as confirmed from 1H NMR titrations of L1 with cages M6(L2)4} and L2 with M3(L1)2}, respectively. Both the interlocked cages of Pd and
