Synthesis, structural characterization, and solid-state NMR spectroscopy of [Ga(phen)(H1.5PO4)2]·H2O and [Ga(phen)(HPO4)(H2PO4)]·1.5H2O (phen=1, 10-phenanthroline), two organic-inorganic hybrid compounds with 1-D chain structures

Two hydrothermally synthesized organic-inorganic hybrid compounds consist of 1-D chains of strictly alternating GaO4N2 octahedra and phosphate tetrahedra, which extend into 3-D supramolecular arrays via π-π stacking interactions of phen ligands and hydrogen bonds. 2H MAS NMR spectroscopy was applied to study the very short hydrogen bonds.
