| Summary: | 碩士 === 國立中興大學 === 化學系 === 84 === Indium(III) oxide (In2O3) is a precursor in the synthesis of
acetato porphyrinato indium(III) complexes, In(Por)(OAc). The
indium porphyrin complexes were prepared by refluxing the
respective porphyrins (tpp, tpyp, tmpp). The yields of the pure
indium complexes were : In(tpp)(OAc), 71; In(tpyp)(OAc), 72%;
In(tmpp)(OAc), 84%> The structures of In(tpp)(OAc), In(tpyp)(
OAc) and In(tmpp)(OAc) were determined by a single-crystal X-ray
structure analysis. The crystals of In(tpp)(OAc), In(tpyp)(OAc)
and In(tmpp)(OAc) are monoclinic , monoclinic and triclinic,
respectively. The acetato group coordinated to indium atom for
In(tpp)(OAc), In(tpyp)(OAc) and In(tmpp)(OAc) are asymmetric-
bidentate, asymmetric-bidentate and symmetric-bidentate ,
respectively.The molecular structure of Sn(tmpp)(OAc)2 has
determinted by X-ray analysis. The tin atom has an octahedral
coors\dination geometry formed by the four nitrogen atoms (Np)
of the porphyrinato group and the two acetate ion. The acetate
groups are unidentately coordinated to the tin(IV) atom. NMR
and IR spectroscopies provide complementary methods for
investigation of the acetate ligand.
