Synthesis and crystal structure of two extensively hydrogen bonded network of Cu(II)

1363-1368Two new Cu(IJ) coordination polymers of higher dimensionality, [CU(L1)2](L2), [L1= N-(2-hydroxyethyl)ethylenediamine, L2= fumarate dianion], (1) and [Cu(L3)2(H2O)2](L4), [L3= 1-(2-aminoethyl)pyrrolidine, L4= squarate dianion], (2), have been synthesized and characterized by X-ray single crystal analysis. Complexes (1) and (2) form 3D and 2D network respectively through extensive hydrogen bonding
