Layered Hybrid of Mo (VI)-Oxide Based On Electron-Rich Phenanthroline Organic Linkers

We have prepared three-dimensional framework of covalently bonded layers of inorganic oxide containing Moister linked by electron-rich organic ligands. The structure of MoO3-(3, 8-phenanthroline) 0.5 consists of corner-sharing of {MoO5N} octahedral. Raman spectra correlate very well to the structural data and illustrate the subtle choice of the ligands used can affect the vibration characteristics of the Mo-O bonds. Magnetization measurements indicate the susceptibility only changes slightly with temperature in the high temperature region above 50 K, an indication of a Pauli paramagnetic metallic behaviour. The increase in the electronic density-of-state due to the electron-rich organic spacer is further confirmed by heat capacity measurement on pressed pellet samples where the electronic specific heat, , is much higher as compared to the bipyridyl counterpart.
