Physico-Chemical Studies of Some 3D-Metal Chelates of Potassium Propan-1,3-Diol Di Xanthate

The present study include the synthesis of potassium propan-1,3-diol di xanthate (PPDDX) along with the preparation of Mn (II), Fe (II and III), Co (II), Ni (II) and Cu (II) chelates of PPDDX. The 1:1 stoichiometry of these chelates is decided with the help of electrometric and chemical analysis. All the complexes are found paramagnetic in nature. The stereo-chemistry and the nature of hybridisation of these chelates are also decided in the present study. All these complexes are found to have high spin octahedral geometry except Cu-complex which is square planar in nature. Excluding Cu-complex all others are found to be sp³d² in nature but Cu-complex has dsp² hybridisation. Metal-sulphur bonding in these complexes is established with the help of infrared spectroscopy.
