Novel vic-dioxime ligands and their poly-metal complexes bearing 1,8-diamino-3,6-dioxaoctane: synthesis, characterization, spectroscopy and electrochemistry Abstract Three novel vic-dioxime ligands containing the 1, 2 and 3), where M = Cu II , Co II , and Ni II , have been obtained with 1:1 metal/ ligand ratio. The Cu II and Ni II poly-metal complexes of these ligands are proposed to be square planar, while also the prepared Co II complexes are proposed to be octahedral with two water molecules as axial ligands. The detection of Hbonding in the [Ni(L 1 SL 1 )] n , [Ni(L 2 SL 2 )] n and [M(L 3 SL 3 )(H 2 O)] n metal complexes by FT i.r. spectra revealed the square planar or octahedral [MN 4 ÁH 2 O)] n coordination of poly-nuclear metal complexes. [MN 4 ] n coordination of the [Ni(L 1 SL 1 )] n and [Ni(L 2 SL 2 )] n complexes were also determined by 1 H-n.m.r. spectroscopy. The ligands and poly-metal complexes were characterized by elemental analyses, FT-i.r., u.v.-vis., 1 H and 13 C-n.m.r. spectra, magnetic susceptibility measurements, molar conductivity, cyclic voltammetry, and differential pulse voltammetric (DPV) techniques.

1 Transition metal complexes of vic -dioximes have been of particular interest as biological model compounds [1]. The high stability of the complexes prepared with dioxime ligands has been extensively used for various purposes including model compounds for vitamin B 12 or trace metal analysis [2]. Coordination compounds of vic -dioximes have been widely investigated as analytical reagents, models for biological systems, such as vitamin B 12 , compounds having columnar stacking thought to be a reason for their semiconducting properties, and recently in dioxime reactions [3]. Among three isomers, namely, anti, amphi , and syn , the first isomer is more liable to form N,N-coordinated planar complexes stabilized by hydrogen bonding [4]. The presence of mildly acidic hydroxyl groups and slightly basic nitrogen atoms make vic -dioximes amphoteric ligands forming corrin-type, square planar, square pyramidal, and octahedral complexes with transition metal ions, such as Co 2+ , Ni 2+ , Cu 2+ , and Co 3+ as central atoms [5].The chemistry of oxime/oximato metal complexes has been developed actively since the time of the first synthesis, e.g. preparation of nickel(II) dimethylglyoximate, and recognition of the chelate five-membered character of this complex by Chugaev [6]. Coordinated oxime ligands and oxime complexes display an impressively rich variety of reactivity modes and give unusual types of chemical compounds [7]. Some recently 1 The text was submitted by the authors in English. reviewed data show that oximes, although being classical ligands [8], display a variety of reactivity modes unusual even for the modern coordination chemistry [9, 10].We have focused on the synthesis and characterization of various types of vic -dioximes and their transition metal complexes [11][12][13][14][15][16][17][18][19]. The aim of this work is the synthesis and characterization of the dioxime ligand and its Co 2+ , Ni 2+ , Cu 2+ , Zn 2+ , and Cd 2+ metal complexes. EXPERIMENTALThe preparation of ( E , E )-dichloroglyoxime has been described previously [20]. All the reagents used were purchased from Merck, Fluka, or Sigma and are chemically pure.Elemental analyses (C, H, N) were performed on a LECO-932 CHNSO elemental analyses apparatus. IR spectra were recorded on a Mattson 1000 FT-IR spectrometer with KBr pellets. 1 H and 13 C NMR spectra were recorded on a Bruker GmbH Dpx-400 MHz high performance digital FT-NMR spectrometer (in DMSO-d 6 ). Electronic spectra were obtained on a Shimadzu 1240 UV spectrometer. Magnetic susceptibilities were determined on a Sherwood Scientific magnetic susceptibility balance (Model MK1) at room temperature using Hg [ Co ( SCN ) 4 ] as a calibrate; diamagnetic corrections were calculated from Pascal's constants. Melting points were determined on a Gallenkamp melting point apparatus.

Notiz über einige halogenierte aliphatische Oxime

Abstract: Ersetzt man eines oder beide der Chloratome des leicht zersetzlichen Dichlorformoxims (Phosgenoxims) durch einen aliphatischen Rest, der auch halogenhaltig sein kann, so erhält man stabile Verbindungen.
