Synthesis and Characterization of Mn(II), Fe(II) and Co(II) Complexes with 4-Hydroxypiperidinedithiocarbamate and their Adducts with Neutral Bases

A new coordination complexes and adducts of the general formulas [M(hpipdtc)2] and [M(hpipdtc)2Ln] where M= Mn(II), Fe(II), Co (II), (hpipdtc)=4-hydroxypiperidinedithiocarbamate, n=1 L= 1, 10phen, en, n=2 L=4-picoline, 3,5-luitidine, triphenylphosphine have been prepared and characterized by metal analyses, infrared, molar conductance measurements, electronic absorption spectra, and susceptibility measurements. Magnetic moments and electronic spectra, suggested tetrahedral geometry for complexes of the type [M(hpipdtc)2] and an octahedral geometry for their base adducts.
