Reports Summarize Supramolecular Research Study Results from University of Hyderabad (Mutual interplay of non-covalent interactions in modulating the geometry of organic linkers in their salts)

By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Supramolecular Research. According to news originating from Andhra Pradesh, India, by NewsRx editors, the research stated, "Two ion-pair compounds (Hhfipbb)2.(H2px2ampy) (1) and (H(2)pxph).(4-Hptz)2 (2) have been synthesized, based on the ligands 4,4'-(hexafluoroisopropylidene)-bis(benzoic acid) (H2hfipbb), 1,4-bis(2-pyridylaminomethyl)benzene (px2ampy), p-xylylenediphosphonic acid (H4pxph) and (5-(4-pyridyl) tetrazole) (4-ptz). Both the compounds -1 and 2 are characterized by routine elemental analyses, IR-, thermogravimetric studies and unambiguously characterized by single crystal X-ray crystallography."

Our news journalists obtained a quote from the research from the University of Hyderabad, "The mutual supramolecular interactions, exhibited by the individual ligands in the organic salts, modulate their geometries to form higher dimensional supramolecular architectures in the crystals of organic salts I and 2. In compound I, the di-cation H2px2ampy2+ modulates its potential hydrogen donor sites in a cis conformation to form a R22(8) hetero synthon with carboxylate oxygen atoms of singly deprotonated Hhfipbbl- anion and thereby restricts the twisting between two benzene rings in the Hhfipbbl- skeleton to form 3D intricate supramolecular architecture. The trans-conformations of H4pxph (compound 2) forms 1D chain through 12 (8) homo synthons, which extends to a 3D porous supramolecular network through interactions with 4-Hpte cations (by twisting them)."

According to the news editors, the research concluded: "The ion components, that are present in both compounds, modulate their geometry from their classical geometries, displayed by them in the metal coordination architectures and inorganic salts.(."
