  Co(II), Ni(II) and Cu(II) mononuclear and polynuclear complexes influenced by the aliphatic spacer length of their O2N2O2 Schiff bases

  摘要：

  M(H2Ln)(H2O)(x) and [M-2(L-n)(H2O)(x)](n) have been obtained by the electrochemical reaction of Co, Ni and Cu anodes with the O2N2O2 symmetrical ligands: N,N'-bis(3-hydroxysalicylidene)-1,2-diaminopropane H4L1, N,N ' -bis(3-hydroxysalicylidene)-1,3-diaminopropane, H4L2, and N,N ' -bis(3-hydroxysalicylidene)-1,4-diaminobutane H4L3. The preferential attainment of mono- or polynuclear compounds seems to be conditioned by the aliphatic spacer length, among other factors.Spectroscopic and magnetic data suggest a distorted tetrahedral array in mono- and polynuclear nickel complexes with H4L2 and H4L3. However, when the aliphatic spacer is shorter, as occurs in Ni(H2L1), physicochemical data are consistent with a square planar geometry. The EPR data for polynuclear copper complexes display the characteristics of quasi-axial symmetry and show spin-spin interactions. Magnetic and electronic data point to high-spin distorted octahedral environments for Co(II) ions in [Co-2(L-3)(H2O)(4)](n). (C) 2001 Elsevier Science B.V. All rights reserved.

  Mono- and poly-nuclear neutral complexes have been obtained by electrochemical reaction of zinc or cadmium anodes with potentially hexadentate ligands H4Ln (n= 1–3). The ligands were prepared by 2∶1 condensation of 3-hydroxysalicylaldehyde and 1,2-diaminopropane, 1,3-diaminopropane or 1,4-diaminobutane, respectively. They can act either as N2O2 dianionic in mononuclear complexes or as N2O4 tetraanionic in polynuclear complexes, where metal ions are held together by μ-phenoxo bridges. X-Ray diffraction study of self-assembled [Zn8(L3)4(H2O)3]·H2O·¼MeCN shows a 3-D cage-like crystal structure, where the ligand units display O2 + N2O2 + O2 polynucleating behaviours.

  通过锌或镉阳极与潜在的六齿配体 H4Ln（n= 1-3）发生电化学反应，获得了单核和多核中性络合物。配体分别由 3-hydroxysalicylaldehyde 和 1,2-二氨基丙烷、1,3-二氨基丙烷或 1,4-二氨基丁烷通过 2∶1 缩合制备而成。它们既可以在单核络合物中作为 N2O2 二阴离子，也可以在多核络合物中作为 N2O4 四阴离子，其中金属离子通过 μ-吩氧基桥连接在一起。对自组装[Zn8(L3)4(H2O)3]- -¼MeCN 的 X 射线衍射研究显示了一种三维笼状晶体结构，其中配体单元显示出 O2 + + O2 多核行为。
