| Abstract: Two oxamidato-bridged complexes with 2,2′-bipy or isophthalic acid co-ligand of formula [Cu2L(2,2′-bipy)(H2O)(ClO4)]ClO4 (1) and [Ni3L2(ipt)(H2O)]H2O (2) have been synthesized and structurally determined by X-ray diffraction, IR and fluorescence spectra. 1 crystallizes in the monoclinic system with P21/n group, a=1.413 1(17) nm, b=1.091 7(13) nm, c=2.325 4(19) nm, β=119.35(5)°, Z=4. 2 crystallizes in the monoclinic system with P21/c group, a=1.159 7(2) nm, b=2.059 9(4) nm, c=1.847 7(4) nm, β=90.788(3)°, Z=4. Complex 1 and 2 are binuclear and trinuclear metal complexes which are linked by oxamide ligand, and the polynuclear fragments are further joined into the 3D and 2D superamolecular framework through hydrogen bonds, respectively.
