  has the trigonal-prismatic geometry only in the solid state. Density functional theory (DFT) calculations were performed to address the question of the preference for a specific coordination geometry in the related MnII complexes [Mn(acac)2(bpy)] (trigonal prismatic) and [Mn(acac)2(phen)] (distorted octahedral). Based on the very small energy differences for the calculated trigonal-prismatic and octahedral

  在本文中，提出了混合配体 MnII 复合物的第一个例子，该复合物具有三角-棱柱配位几何结构和简单、无害的双齿配体。通过 EPR 光谱、磁化率测量和 XRD 研究的 [Mn(acac)2(bpy)] 的溶液和固态结构显示：单晶为六边形，空间群 P61，晶胞尺寸 a = 8.0482(9) A, c = 51.602(10) A, V = 2894.6(7) A3 和 Z = 6。复合物仅在固态下具有三角棱柱几何。进行密度泛函理论 (DFT) 计算以解决相关 MnII 配合物 [Mn(acac)2(bpy)]（三角棱柱）和 [Mn(acac)2(phen) 中特定配位几何的偏好问题]（扭曲的八面体）。基于计算的三角-棱柱和八面体结构的非常小的能量差异，可以得出结论，晶体堆积效应必须对确定 [Mn(acac)2(bpy)] 的三角-棱柱结构有很大贡献。(© Wiley-VCH Verlag GmbH

  The compounds [M(pd)(2)(L)] (where M is manganese(II) or copper(II); pd is pentane-2,4-dionate; and L is piperazine (pipz), 4-cyanopyridine (4-cyanopy), quinoline (quin) or 2,2'-bipyridine (bipy)) were synthesized and characterized by elemental analysis, melting points, thermal studies and electronic and IR spectroscopy. The enthalpies of dissolution of adducts, metal pentane-2,4-dionate and ligands in a 1:3 (v/v) mixture of aqueous HCl 1.2 M and 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 reaction (Delta(r)H(theta)), the standard enthalpies of formation (Delta(f)H(theta)), the standard enthalpies of decomposition (Delta(D)H(theta)), the lattice standard enthalpies (Delta(M)H(theta)) and the standard enthalpies of the Lewis acid/base reaction in the gaseous phase (Delta(r)H(theta)(g)). The mean standard bond dissociation enthalpies of the manganese-nitrogen and copper-nitrogen bonds have been determined. (C) 2000 Elsevier Science B.V. All rights reserved.
