    摘要:
    将Cd(O3SCF3)2与化学计量的1,3-噻唑烷-2-硫酮(tztH)反应,可得到[Cd(tztH)4](O3SCF3)2(1)的单体。当tztH:Cd [Formula: see text] 2时,Cd(NO3)2·4H2O与tztH的反应会生成[Cd(tztH)4][Cd(O2NO)4](2)。单晶X射线分析确定了1和2的结构。1的无色晶体为正交晶系,空间群Fdd2,每个晶胞有八个分子(Z = 8),尺寸为a = 20.139(3) Å,b = 23.332(5) Å,c = 14.214(3) Å。2的晶体为四方晶系,空间群I [Formula: see text],每个晶胞有四个分子(Z = 4),尺寸为a = 13.8853(11) Å,c = 8.077(2) Å。1和2中首次表征了离子[Cd(tztH)4]2+。在1和2中,阳离子具有C2和S4点群对称性。在两种情况下,配体为S-配位,CdS4核为扁平四面体。在2中,八配位的阴离子[Cd(O2NO)4]2-第二次被表征。报道了固体1和2的113Cd CP MAS NMR数据,以及通过熔融Cd(NO3)2·4H2O与不同摩尔比的tztH,以及通过Cd(O3SCF3)2与六摩尔当量的tztH形成的固体所产生的固体。在Cd(NO3)2·4H2O:tztH混合物中,鉴定的物种包括未反应的镉盐2([Cd(tztH)4](NO3)2)和可能的Cd(tztH)3(NO3)2。只有在使用大量过量的tztH时,[Cd(tztH)4](NO3)2才成为主要物种。在tztH:Cd > 4的混合物中,Cd(NO3)2·4H2O和Cd(O3SCF3)2不形成含有超过四个tztH配体的配合物。在MeOH中报道了Cd(ClO4)2·6H2O:tztH混合物的降温111Cd NMR数据。鉴定的物种是Cd(tztH)w2+(solv)(w = 0–3)。关键词:1,3-噻唑烷-2-硫酮,镉配合物,X射线分析,113Cd CP MAS NMR,溶液111Cd NMR,四(1,3-噻唑烷-2-硫酮)镉(2+)阳离子,四(硝酸根-O,O')镉酸根(2–)阴离子。

    Synthesis, vibrational spectroscopy and EXAFS analysis of some divalent and trivalent trifluoromethanesulphonato complexes
    摘要:
    The syntheses of trifluoromethanesulphonato (OTf) complexes of Co(II), Ni(II), Cu(II), Fe(III) and Ga(III) by the reaction of simple metal salts (Cl-, Br-, CO32-, ClO4-) or metallic gallium with trifluoromethanesulphonic acid have been systematically investigated.Comparison of the vibrational spectra of coordinated OTf in these complexes with that in simple ionic salts indicates the ligand to be bridging bidentate in M(OTf)3, M = Ga, Fe and in M(OTf)2, M = Cu and bridging tridentate in M'(OTf)2, M' = Co, Ni, Cd. EXAFS spectroscopic data can be interpreted in terms of layered structural arrangements for Co, Ni, Cd and Ga trifluoromethanesulphonato complexes, similar to that of the corresponding anhydrous metal perchlorates studied previously. In Cu(OTf)2, however, the copper atom is in a square planar environment. The short metal-oxygen distances, 1.96-2.09 angstrom are consistent with strong interactions between the ligand and metallic centre.

    products were Cd(II)4L4 tetrahedra, one with ligands puckered inward, and the other outward. The third product was a Cd(II)8L8 structure having all mer stereochemistry, contrasting with the fac stereochemistry of the tetrahedra. These three complexes were observed to coexist in solution. The equilibrium between them could be influenced through guest binding and specific interactions between aniline subcomponents

    The new ligand 2,6-bis[2-(diphenylphosphino)ethylsulfanylmethyl]pyridine, 2,6-(Ph2PCH2CH2SCH2)2C5H3N (L1), has been synthesized. Reaction of [Cu(MeCN)4][CF3SO3] or AgNO3 with 1 molar equivalent of L1 gave [CuL1][CF3SO3] 1 or [AgL1][NO3] 2, in good yield. Reaction of equimolar quantities of L1 and AuI, followed by precipitation with AgO3SCF3, gave [AuL1][CF3SO3] 3. In the crystal structure of 2·H2O, L1 co-ordinates to Ag via a P2S2 donor set in a distorted tetrahedral geometry. Reaction of M(O3SCF3)2 (M = Zn or Cd) with 1 molar equivalent of L1 gave [ML1(O3SCF3)2] (M = Zn 4 or Cd 5). Crystal structure analysis of 5 showed that the molecule has symmetry 2, with all five donor atoms of L1 and a pair of monodentate CF3SO3– ligands arranged in an unusual distorted pentagonal bipyramidal co-ordination geometry about the cadmium centre.

    macrocyclic ligand is in a coordination‐enforced strained conformation. Removal of the metal cation by a competing ligand yields a highly reactive [1+1]‐macrocycle, which then undergoes hydrolysis to transient non‐cyclic aminoaldehyde species, which then recondense to a strain‐free [2+2]‐macrocyclic resting state. The process can be monitored by 1H NMR spectroscopy. Energy differences between different conformational
    通过施加各种类型的电子和构象约束,使分子结构从其热力学最稳定的状态发生位移,会生成高度应变的实体,这些实体倾向于通过进行结构变化或化学反应来释放累积的应变能。后一种情况相当于可能引起特定化学转化的应变诱导反应性(SIR)。一个特殊的案例涉及可能出现SIR的动态共价化学,由此可逆反应通过偶联至高能态而被激活。我们在此描述了一种涉及可逆亚胺形成反应的动态共价化学(DCC)系统。它基于形成应变的大环双亚胺金属配合物,其中大环配体处于高能形式,受金属阳离子的配位作用增强。随后的脱金属生成高度应变的自由大环,该大环通过水解释放并重新组装成静止状态,从而释放其累积的应变能。具体来说,金属模板的二醛与线性二胺的缩合会生成双亚胺[1 + 1]-大环络合物,其中大环配体处于配位强化的应变构象中。通过竞争性配体去除金属阳离子会产生高反应性的[1 + 1]-大环,然后水解为瞬态非环状氨基醛物质,然后再缩合为无应变的[2
