Аннотация

A novel inorganic-organic hybrid salt, hexanediammonium heptamolybdate (C6H18N2)2[H2Mo7O24]×7H2O has been synthesized and characterized by elemental analyses, IR, TGA, cyclic voltammetry, UV and X-ray single crystal diffraction. It crystallizes in triclinic space group P -1 with a = 10.0619(2) Å, b = 12.059(2) Å, c = 20.044(3) Å, a = 97.06(1)°, b = 91.56(1)°, g = 110.59(2)° and Z = 2. The crystal structure shows that seven MoO6 distorted octahedra share edges which have four ranges of Mo-O bond distances. The heptamolybdate anion of the crystal has approximate mm 2 point symmetry and its structure is similar to that observed in other heptamolybdates. The titled compound consists of the protonated hexanediamine cations and the inorganic [H2Mo7O24]4- oxomolybdate anions, linked by hydrogen-bonding interactions.
