Abstract
The 1 ∶ 4 complexes of cobalt (II) and manganese (II) thiocyanates with morpholine (Morph), [M(NCS)2(Morph)4] (M=Co, Mn), were prepared and studied by means of thermogravimetry, derivative thermogravimetry and differential scanning calorimetry. By thermal treatment of the above compounds, the 1∶2 and 1∶1 complexes, [M(NCS)2(Morph)2] (M=Co, Mn; n=1, 2), were formed. Magnetic data, infrared and electronic spectra and molar conductance values for the compounds are reported. All the complexes contain N-bonded morpholine and the 1∶4 complexes are suggested to have a monomericcis pseudooctahedral structure with N-bonded thiocyanate, whereas the 1∶2 and 1∶1 complexes are considered to have a six-coordinated polymeric configuration involving bridging NCS groups.
