Abstract
An inorganicorganic hybrid material HMTAH2ZnH2O5ZnH2O4Mo7O24·2H2O 1 where HMTAH = protonated hxamethylenetetramine has been synthesized and structurally characterized The compound 1 crystallizes in a monoclinic space group C2/c The crystal data of 1 a = 43123 b = 1239910 c = 1628513 β = 11113111 Z = 8 Its crystal structure shows that two different ZnIIaqua complexes ZnH2O52+ and ZnH2O42+ are covalently coordinated to a heptamolybdate anion Mo7O246− resulting in an anionic species of polyoxometalate supported zincaqua complexes ZnH2O5ZnH2O4Mo7O242− that is stabilized with two protonated hexamethylenetetramine cations in the title compound 1 In the crystal structure both lattice water molecules are found to interact with the heptamolybdate cluster anion and the protonated hexamethylenetetramine cation resulting in an intricate threedimensional hydrogen bonding network Interestingly compound 1 exhibits catalytic activity towards oxidation of some primary alcohols
