A metal-organic framework based on
5-iodo-isophthalic acid (5-iipaH2) and the ancillary nitrogen
ligand 1,3-bi(4-pyridyl)propane (bpp), namely
[Cd(5-iipa)(bpp)(H2O)]n (1), has been
synthesized, and characterized by IR spectroscopy, elemental analysis,
thermogravimetry, and X-ray crystallography. Complex 1 shows
a two-fold interpenetrating 3D diamond-like architecture that is
stabilized by hydrogen bonding, π ··· π, I··· π, and C−H··· π interactions.
Key words: 5-Iodo-isophthalic Acid, Lattice Interpenetration, Diamond-like Architecture, Supramolecular Structure, Cadmium
