摘要：
Two new helical Cu(II) coordination polymers, [Cu(2,2'-bpy)(Hsgly)]Cl center dot 2H(2)O(H(2)sgly = N-(2-hydroxylbenzyl)glycine) (1) and [Cu(2,2'-bpy)(HsaIa)](NO3) center dot 2H(2)O(H(2)sala = N-(2-hydroxylbenzyl)-L-alanine) (2) were synthesized. Single crystal X-ray diffraction analysis indicated that both complexes showed helical chains arrangement of Cu(II) centers bridged by carboxyl groups. The magnetic measurements showed complex 1 exhibited ferromagnetic interaction while there was no interaction between the Cu(II) centers in complex 2. (C) 2005 Elsevier B.V. All rights reserved.
