The solid state reactions of phenanthroline (Phen) with Co (Ac)2
·4H2O. Ni(Ac)2·4H2O
Cu(Ac )2·H2O and Zn (Ac )2·2H2O have been investigated at room telnpelature. Influences of molecular structures of these reactants on solid state reactions are discussed.The solid products are characterized by elemental analysis
