A new complex {[Na-2(H2O)(3)(mu-L)(2)Cu](4)}infinity (L = N-methyliminodiacetic acid) has been synthesized and structurally characterized. The complex crystallizes in the monoclinic, space group C2/c, with the unit cell parameters a = 16.556(3) angstrom, b = 8.0622(13) angstrom, c = 12.671(2) angstrom, alpha = 90 degrees, beta = 95.849(2)degrees, gamma = 90 degrees. The central metal Cu (II) ion is coordinated with two nitrogen atoms and four oxygen atoms belonging to two ligands. Simultaneously, the sodium is six-coordinated with oxygen atoms coming from the ligand and water molecule; the sodium atoms related are bridged by oxygen atoms, forming a sodium chain. The structure consists of CuL2 moieties linked by sodium chain via the exo oxygen atoms of two ligands, forming a novel three-dimensional structure. Moreover, elemental analysis, IR, UV-vis, ESR spectroscopy and thermal stability were determined.
