Five new coordination polymers Cu(phen)(H2O)(phth)·CH3OH(1),[Cu(2,2’-bipy)(H2O)](phth).3.5H2O(2),Zn(phen)(phth)(H2O).1.125H2O(3) and [M(4,4’-bipy)(H2O)2](phth).2H2O[M=Zn(4),Mn(5)](H2phth=phthalic acid,bipy=bipyridine,phen=l,10-phenanthroline) have been synthesized from the amino acid derivatives(phthalyl-I-valine,H2L) and structurally characterized.H2L was hydrolyzed into phth2- group during the reaction,but the strucure feature was different from that of the complex directly synthesized from H2phth in the reported literature,revealing that H2L played an important role in composing the novel compounds.Compounds 1,2 and 3 are all 1D chains,but the differences are that compound 1 is further hydrogen-bonded into 2D networks,and compound 2 is further extended into 3D supramolecular network through π-π stacking and hydrogen-bonding interactions.However,compound 3 is a 1D helix chain structure and further links into 2D networks through π-π stacking.Compounds 4 and 5 are isostructural and exhibit the same 2D layers,which are further connected by hydrogen-bonding interactions to form 3D supramolecular network.Antiferromagnetic superexchange was observed for compounds 1,2 and 5.
