title: [Infrared spectra and coordinated mode of manganese (II), iron (II), cobalt (II) complexes with dithiolene and 1, 10-phenanthroline-5, 6-dione ligands].
abstract: The infrared spectra and far-infrared spectra of M(mnt)(phen-5, 6-dione) [M= Manganese(II), Iron(II), Cobalt(II). mnt2- = 1, 2-dicyano-1, 2-ethylenedithiolate or maleonitriledithiolate, phen-5, 6-dione = 1, 10-phenanthroline-5, 6-dione] are reported in detail. In infrared spectra and far-infrared, characteristic v (C[triplebond]N) , v (C==)) , (C==C) v (C-N), v (C-S), v (M-S) and V(M-N) are very strong. Far-infrared spectra shows that M-S bond is slightly strong than M-N bond. Through comparing infrared spectra, simple regular coordinate mode of M(mnt) (phen-5, 6-dione) is analysed. The relation between infrared spectra and structure of the title complexes is discussed. In the title complexes, transition metals ion with 1, 2-dicyano-1, 2-ethylenedithiolate and 1, 10-phenanthroline-5, 6-dione form quadridentate distortion tetrahedral configuration molecules. The symmetry is approximate to C2 and C2v.
