| Abstract: The complex, [Cu2(L-ala)2(phen)2]n·2nClO4·2nH2O(L-ala=L-alaninate, phen=1,10-phenanthroline) has been synthesized and investigated by elemental analysis, IR spectroscopy, and X-ray diffraction methods. The complex crystallizes in the monoclinic space group P21 with a=1.161 1(4) nm, b=0.717 2(2) nm, c=2.074 1(7) nm, β=101.028(6)°, V=1.695 4(9) nm3, Dc=1.760 g·cm-3, Z=4, μ=1.493 mm-1, F(000)=916, R=0.052 2, wR=0.127 9 for 7 131 unique reflections. The cations of [Cu2(L-ala)2(phen)2]n2n+ have an one-dimensional polymeric structure, due to the bridging of two Cu(phen)2+ units by a carboxylate group of L-alaninate, and each Cu(Ⅱ) ion is in a slightly distorted square-pyramidal coordination geometry, with the phen (N,N′) and the L-ala(N,O) acting as bidentate ligands in the equatorial plane and another carboxylate oxygen atom from a symmetry-related neighboring L-alaninate ion in the apical position.
