pH-dependent assembly of a series of inorganic-organic hybrid molybdenum(v) phosphate

Four inorganic-organic hybrid materials based on poly(oxomolybdophosphate) cluster building blocks have been obtained by hydrothermal methods. 1 shows a 2-D sheet structure, 2 and 3 possess 1-D chain structures and 4 is the discrete cluster. Crystal structural analysis reveals that the dimensionality and organization of those compounds can be tuned by the pH value of the reaction system. In addition, the fluorescence emissions are analysed of compounds 1, 2 and 4 containing Cd atoms with d(10) electronic configuration red-shift along with the increase in the dimensions of those compounds.
