碩士 === 中國文化大學 === 應用化學研究所 === 86 === ABSTRACT The hydrothermal
synthesis and characterization of a novel organic/inorganic
hybrid compound : viz.[(MoO3)m(2,2''-bipyridine)n] and [(MoO3)
m(1,10-phenanth-roline)n] is present . These novel compounds
were characterized by various techniques including Raman and IR
spectroscopy , XRD , SEM and thermogravi-metric analysis .
Vibrational analysis of these compounds by Raman and IR datashow
a novel molybdenum structure with 2,2''-bipyridine being
coordinated withmolybdenum atom . The X-ray powder diffraction
data of these compounds areindexed to a monoclinic cell with
a=14.313(4)A , b=9.603(2)A , c=7.288(2)A ,β=102.07(2)°. The
structure exibits a chain-like framework consisting ofcorner-
shared distorted octahedron (MoO4N2) with the 2,2''-bipyridine
servingas a bidentate ligand whose ring fanning out from the
chain . Structural evolution of [(MoO3)m(2,2''-bipyridine)n] and
[(MoO3)m(1,10-phenanthroline)n]upon removal of 2,2''-bipyridine
and 1,10-phenanthroline through thermal treatment were studied
by in-situ Raman spectroscopy and thermogravimetricanalysis .
(MoO3)(2,2''-bipyridine) retain it''s structural integrity
until290℃ and a transition to (MoO3)2(2,2''-bipyridine) is
identified around 330℃before the final conversion to MoO3
around 400℃ . (MoO3)2(2,2''-bipyridine)and (MoO3)3(2,2''-
bipyridine)2 have no transition upon the thermal treatmentand
also the [(MoO3)m(1,10-phenanthroline)n] . They all finally
converse to MoO3 at different temperature .
