Popis: | The atomic structure of crystals of the complex [Eu(NO3)23hmpa] NO3·HQuin , (hmpa – hexamethylphosphortriamide, HQuin – quinaldic acid) characterized by intensive luminescence and triboluminescence has been determined by the X-ray method. The noncentro-symmetric crystals of the compound are rhombic : a = 16.8193(3), b = 12.2877(2), c = 27.6516(5) A, пр. гр. Pca2(1), Z = 4, ρ calc. . = 1.427 g/сm3. The crystals have a structure of the insular type which is presented by the isolated complex molecules, outer-sphere NO3 − – groups, and neutral molecules of quinaldic acid. Some structural aspects of formation of the luminescent and triboluminescent properties of the compound were discussed: the role of break planes in the crystal destruction was revealed. |
