Synthesis of cobalt(II) complexes of derivatised salicylaldoxime ligands; X-ray crystal structures of DMSO adducts of bis(3-nitro-5-methylsalicylaldoximato)cobalt(II) and bis(3-nitro-5-phenylsalicylaldoximato)cobalt(II)

characterised. The cobalt(II) complexes [CoL2] (L=L1–5) of these ligands were synthesised and characterised by microanalysis, atomic absorption, infra and mass spectroscopy. X-ray structure analysis was carried out on the adducts [Co(L)2(dmso)2] (L=L4,5). These are the only structurally characterised cobalt salicylaldoxime complexes apart from three five-coordinate nitroso complexes [CoL2(NO)] reported
合成并表征了五种水杨醛肟肟配体(HL 1-5),类似物。合成了这些配体的钴(II)配合物[CoL 2 ](L = L 1-5),并通过微分析,原子吸收,红外和质谱进行了表征。对加合物[Co(L)2(dmso)2 ](L = L 4,5)进行X射线结构分析。这些是除三个五配位的亚硝基配合物[CoL 2]以外唯一在结构上具有特征性的钴水杨醛肟配合物。(NO)]在1980年代报道(J.Crystallogr.Spectrosc.Res.13(1983)413; J.Crystallogr.Spectrosc.Res.16(1986)6)。表征的两个加合物的结构显示八面体配位,其中两个dso分子占据轴向位置,每个分子中的两个水杨醛肟单元占据赤道位置。已经发现在两个配位体中在两个配体上引入硝基可稳定氧化(II),而不是(III)。发现这些基团似乎对配体内氢键起重要作用,从而导致分子两侧的三中心H键,进而采用不寻常的椅子构象。
