  Two new µ-carboxylato-bridged binuclear copper(II) complexes [Cu2(bpea)2 (µ-C2O4)](ClO4)2 · H2O (1) and [Cu2(bpma)2 (µ-ta)](ClO4)2 · H2O (2) (bpea = N,N-bis(2-pyridylmethyl)ethylamine; bpma = N,N-bis(2-pyridylmethyl)methylamine; ta = terephthalate dianion) have been synthesized and structurally determined by X-ray diffraction. Complex 1 is crystallized in a monoclinic space group C2/c with unit cell parameters a = 21.539(17) Å, b = 12.608(10) Å, c = 13.117(11) Å, β = 96.788(13)°. In 1, each Cu(II) is five-coordinate, square-pyramidal geometry with a CuN3O2 donor set. Complex 2 is crystallized in a monoclinic space group P21/n with unit cell parameters a = 11.346(3) Å, b = 15.418(4) Å, c = 11.958(3) Å, β = 116.519(4)°. In 2, each Cu(II) also is square-pyramidal CuN3O2 core, where three N- and one O-donors are equatorial and an oxygen of the bridging ligand occupies the axial site with a weak link. Elemental analyses, IR, UV and EPR spectra of the complexes were determined.
