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.CCDC:277541.
