Abstract

The atomic structure of crystals of the complex [Tb(NO ) (Acac)(Phen) ]·H O, (AA - acetylacetonate anion, Phen - 1,10-phenanthroline) characterized by an intensive luminescence and triboluminescence has been determined by means of an X-ray structural analysis method. Centrosymmetric crystals have a monoclinic syngony: a = 11.2298(1), b = 9.6492(1), c = 13.2745(1) Å, β = 101.290(1), space group P2/n, Z = 2, ρ = 1.790 g/cm . The crystal structure is represented by individual С Н N O Tb complexes linked through van der Waals interactions with clearly expressed cleavage planes. The Tb(III) atom coordination polyhedron reflects the state of a distorted square antiprism. The structural aspects of the suggested model of formation of the triboluminescent properties were considered and the role of the cleavage planes discussed. Copyright © 2016 John Wiley & Sons, Ltd.

摘要

通过X射线结构分析方法确定了配合物[Tb(NO₃)₃(Acac)(Phen)]·H₂O（AA - 乙酰丙酮阴离子，Phen - 1,10 - 菲啰啉）晶体的原子结构，该配合物具有强烈的发光和摩擦发光特性。中心对称晶体属于单斜晶系：a = 11.2298(1)，b = 9.6492(1)，c = 13.2745(1) Å，β = 101.290(1)，空间群P2/n，Z = 2，ρ = 1.790 g/cm³。晶体结构由通过范德华相互作用连接的单个C₁₉H₁₅N₃O₇Tb配合物组成，具有明显的解理面。Tb(III)原子配位多面体反映了扭曲的四方反棱柱的状态。考虑了所提出的摩擦发光性质形成模型的结构方面，并讨论了解理面的作用。版权所有© 2016约翰威立父子有限公司。
