摘要：
New luminescent cluster complex (Bu4N)(2)[W6I8(N3C6H4)(6)] (I) is obtained by the reaction of (Bu4N)(2)[W6I8(OOCCH3)(6)] with 1-trimethylsilyl-1,2,3-benzotriazole (Me3Si-N3C6H4) is obtained. The crystal structure is determined for cocrystallizate I with 1,2,3-benzotriazole (Bu4N)(2)[W6I8(N3C6H4)(6)]center dot 4(N3C6H5) (I center dot 4BTA). According to single crystal X-ray diffraction data, tungsten atoms of the {W6I8}(4+) cluster core are monodentate coordinated by N1 atoms of 1,2,3-benzotriazolate ligands (average W-N distance 2.20 angstrom). For the powder sample of I bright phosphorescence is revealed with the emission maximum at 640 nm, phi = 24%, tau = 266 mu s (in the air atmosphere). Complex I is characterized by electrospray mass spectrometry, proton magnetic resonance, C, H, N elemental analysis, and IR spectroscopy.
