Abstract: | Synthesized and in solid state characterized compounds correspond to the following types Mn(NCS)2LmL'n] · x D, Mn(NCS)2Ly]z, and MnX2(CH3SCN)(CH3OH)] · x D (L=CH3OH or O-donors; L =CH3SCN or N-donors; D=solvent molecules; x=0, 1 or 2; m=0, 1 or 2; n=1, 2 or 3; y=0, 1, 2, 3 or 4; z 2; X=Cl or Br). Derivatographic investigations confirm the formation of intermediates, especially for L=H2O the existence of thermic stable partially dehydrated ( hydrate poor ) species (y=1/2 or 1/3) and -NCS-bonding with different ligating atoms. Solid state FT-IR analysis were carried out for band shapes, measurements of the integrated intensity, and correlations between located absorption maxima for v(CN), v(CS), (NCS), v(MnN), and v(MnS) and the thiocyanate bond mode. |
