5-benzenetricarboxylic acid, H2bdc = isophthalic acid, 5-OH-H2bdc = 5-hydroxyisophthalic acid, D-H2ca = D-camphor acid), have been hydrothermally synthesized. These compounds were structurally characterized by IR spectroscopy, elemental analysis and X-ray single-crystal diffraction. Compound 1 exhibits a 2D → 3D framework with an unusual parallel polycatenation of corrugated 2D (4,4) nets. Compounds 2–4 are structurally
