  • Methylation of Tethered Thiolates in [(bme-daco)Zn]<sub>2</sub> and [(bme-daco)Cd]<sub>2</sub> as a Model of Zinc Sulfur-Methylation Proteins

    The dimeric dithiolate complex [1,5-bis(mercaptoethyl)-1,5-diazacyclooctanato]zinc(II), [(bme-daco)Zn](2) or Zn-1, and its cadmium analogue, Cd-1, were investigated as models for the active site of zinc-dependent methylation proteins. The key issue addressed was whether alkylation of a thiolate in a relatively rigid tetradentate ligand would result in coordination of the thioether product to the metal

    The monoanionic complexes (C5H5NH)[ZnBr3(C5H5N)] (1) and (n-CH3C5H4NH)[ZnBr3(n- CH3C5H4N)] (n = 2 (2), 3 (3), 4 (4)) were prepared by crystallization from ethanol solutions through redistribution reactions between the corresponding dianionic complexes (C5H5NH)2[ZnBr4] (5) and (n-CH3C5H4NH)2[ZnBr4] (n = 2, 3 (6), 4 (7)) and the neutral complexes [ZnBr2(C5H5N)2] (10) and [ZnBr2(n-CH3C5H4N)2] (n = 2 (8), 3, 4 (9)). The crystal structures of 1, 4, 9, and 10 were determined; 1: triclinic, P1, a = 7.6957(5), b = 7.7975(4), c = 12.4768(8) Å , α = 90.857(5), β = 95.917(5), γ = 107.899(6)°, Z = 2, 150 K; 4: monoclinic, P21/c, a = 14.8369(6), b = 13.9504(5), c = 8.0041(3) Å , β = 96.318(4)°, Z = 4, 299 K; 9: monoclinic, P21/c, a = 14.2883(5), b = 8.0269(3), c = 13.6031(5) Å , β = 100.581(4)°, Z = 4, 150 K; 10: monoclinic, P21/c, a = 8.7388(5), b = 17.9730(10), c = 8.5452(5) Å , β = 100.024(6)°, Z = 4, 300 K. The cation and anion are paired up via bifurcated hydrogen bonds in the structure of 1 and via a normal N-H· · ·Br hydrogen bond in the structure of 4. 81Br NQR resonance lines coinciding in number with the Br atoms in the chemical formulae were observed for the compounds 1 - 5 and 7 - 9 throughout the temperature range from 77 to ca. 320 K. The comparison between the net charges on the Br atoms obtained by the Townes-Daily analysis or by the Mulliken population analysis seems to indicate that the formation of the intermolecular N-H· · ·Br hydrogen bonds and the π-π and the CH3-π interactions in the crystal structures of the monoanionic complexes are the driving forces to the redistribution reactions

    通过从乙醇溶液中晶化,通过相应的二阴离子配合物(C5H5NH)2[ZnBr4](5)和(n-CH3C5H4NH)2[ZnBr4](n = 2,3(6),4(7))与中性配合物[ZnBr2(C5H5N)2](10)和[ZnBr2(n-CH3C5H4N)2](n = 2(8),3,4(9))之间的重新分配反应制备了单阴离子配合物(C5H5NH)[ZnBr3(C5H5N)](1)和(n-CH3C5H4NH)[ZnBr3(n-CH3C5H4N)](n = 2(2),3(3),4(4))。确定了1、4、9和10的晶体结构;1:三斜晶系,P1,a = 7.6957(5),b = 7.7975(4),c = 12.4768(8)Å,α = 90.857(5),β = 95.917(5),γ = 107.899(6)°,Z = 2,150 K;4:单斜晶系,P21/c,a = 14.8369(6),b = 13.9504(5),c = 8.0041(3)Å,β = 96.318(4)°,Z = 4,299 K;9:单斜晶系,P21/c,a = 14.2883(5),b = 8.0269(3),c = 13.6031(5)Å,β = 100.581(4)°,Z = 4,150 K;10:单斜晶系,P21/c,a = 8.7388(5),b = 17.9730(10),c = 8.5452(5)Å,β = 100.024(6)°,Z = 4,300 K。在1-5和7-9化合物中,从77到约320 K的温度范围内观察到与化学式中的Br原子数量相符的81Br NQR共振线。通过Townes-Daily分析或Mulliken电荷分析得到的Br原子的净电荷之间的比较似乎表明,晶体结构中的分子间N-H···Br氢键、π-π和CH3-π相互作用是单阴离子配合物的重新分配反应的驱动力。在1的结构中,阳离子和阴离子通过分叉氢键成对出现,在4的结构中,它们通过正常的N-H···Br氢键成对出现。
  • Thermochemistry of adducts of some bivalent transition metal bromides with pyridine
    作者:Pedro Oliver Dunstan

    日期:2007.5
    The compounds [MBr2(py)(2)] (where M is Mn(II), Co(II), Ni(II), Cu(II) or Zn(II); py = pyridine) were synthesized and characterized by melting points, elemental analysis, thermal analysis and electronic and IR spectroscopy. The enthalpies of dissolution of the adducts, metal(II) bromides and pyridine in 25% (v/v) 1.2 M aqueous HCl in methanol were measured and by using thermochemical cycles, the following thermochemical ;parameters for the adducts have been determined: the standard enthalpies for the Lewis acid/base reactions (Delta H-r(theta)), the standard enthalpies of formation (Delta H-r(theta)), the standard enthalpics of decomposition (Delta H-D(theta)), the lattice standard enthalpies (Delta H-M(theta)) and the standard enthalpies of the Lewis acid/base reactions in the gaseous phase (Delta H-r(theta)(g)). The mean bond dissociation enthalpies of the M(II)-nitrogen bonds have been estimated as well as the enthalpies of the adducts formation in the gaseous phase. (c) 2007 Elsevier B.V.
