摘要
A novel complex of Eu(III) tetrakis-thenoyltrifluoroacetonate with the outer-sphere cation 2-(E)-1-(2-thenoyl)ethylidene)-1-hydrazonium carboxyimidoamide (Q) of the composition Q[Eu(TTA)(4)]center dot H2O (TTA, thenoyltrifluoroacetonate-ion; Q, outer-sphere cation) characterized with intense luminescence and triboluminescence has been synthesized. The structure of the centrosymmetric hydrazonium crystal is composed of complex anions of the composition [Eu(TTA)(4)](-), which are stacked in layers parallel to the plane (100), whereas interlayers of organic cations are located between the layers. A structural model for the formation of triboluminescent properties has been suggested.
