Two novel chiral organic–inorganic hybrid materials based on two important heteropolyoxometallate namely Preyssler and Wells–Dawson anions, (Hval)2 (Hgly)(H3O)6K5[Na(H2O)P5W30O110]19.5H2O (1) and (Hpro)6[P2W18O62]8H2O(2), were prepared and characterized by elemental analysis, X-ray diffraction, and infrared spectroscopy. The mixed amino acid as cations, Preyssler and Wells–Dawson as anions held together into a 3D-network through hydrogen-bonding interactions. The most unique structural features of 1 and 2 are their 3D-inorganic infinite tunnel-like framework. It results a weak van der Waals interlayer interaction. This provides a desirable condition to use its potential as a host in a host–guest complex. The chirallity for these two crystal structures, with the space group P21 has been observed. The electrostatic forces and hydrogen bonding, keep these ‘‘adducts’’ stable in the solid state.
