Synthesis and characterization of novel ternary and quaternary reduced molybdenum oxides

This thesis is divided into 8 sections: synthesis and characterization (char.) of Ba{sub 3}Mo{sub 18}O{sub 28} (an oligomer with four traps edge-sharing Mo octahedra); synthesis and char. of K{sub x}M{sub y}Mo{sub 14}O{sub 22} (M=Sn, Pb, Sr) (oligomers with three traps edge-sharing Mo octahedra); synthesis and char. of K{sub 0.19}Ba{sub 3.81}Mo{sub 22}O{sub 34} (an oligomer with five traps edge-sharing Mo octahedra); synthesis and char. of Ti{sub 0.31}Fe{sub 1.69}Mo{sub 4}O{sub 7} (a material containing closest-packing of infinite chains of octahedral Mo clusters); synthesis and char. of K{sub x}M{sub 2-x}Mo{sub 10}O{sub 16} (M=Ca, Sr, Gd) (oligomers with two traps edge-sharing Mo octahedra); synthesis and char. of the RE{sub 4}Mo{sub 4}O{sub 11} series; synthesis and char. of Pb{sub 0. 31}WO{sub 3} (a tetragonal tungsten bronze containing lead); and examination of superstructure in Fe{sub 1.89}Mo{sub 4.11}O{sub 7}, Sn{sub 0.9}Mo{sub 4}O{sub 6}, InMo{sub 4}O{sub 6}, and Mn{sub 1. 5}Mo{sub 8}O{sub 11} by electron microscopy.
