摘要
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.
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） nm^3, 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]n^2n＋ 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.
