[Epub ahead of print]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) Å, 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. Read More
