New coordination monomers of copper, Cadnium and manganese with maleamic acid ligands

New coordination monomers of Mn (II), CU(II) and (Cd(II) with different maleamic acid moieties have been synthesised. The tetra or hexacoordinated complexes of Cu have following formulas: Cu(2CPMA)2, Cu(3CPMA)2, Cu(APMA)2 Cu(DCPM)2 H2O, Cu(1,2PBMA) and Cu (1,PBMA). The tefta coordinated complexes of Mn and Cd have the following formulas: M(2CPMA)2 Mn(3CPMA)2, while their hexa-coordinated complexes have the formulas: M(PMA)2. 2H2O, M(I,2PBMA).2H2O, M(1,4PBMA). 2H2O, and Cd(DCPMA)(CH3 COO)22H2. O. Free radical and thermal polymerization was performed on these complexes. Viscosity measurement show degree of polymerization Cu polymers are thermally more stable than Mn and Cd polymers. The polymers of tetradentate units (1,2 or 1,4 PBMA) or tridentate units (APMA) are more thermally stable than bidentate units. (authors). 29 refs., 4 tabs., 1fig
