Mesomorphic dithiooxamide complexes of platinum(II)
Complexation of non-mesomorphic dithiooxamide ligands to Pt(II) leads to square planar complexes which exhibit mesomorphic properties. The synthesis of these complex was accomplished in three steps: the formation of bisamides, starting from conveniently s
