- Аннотация: The reaction of cyclic trimeric perfluoro-o-phenylenemercury (o-C6F4Hg)(3) (1) with the polyhedral [B12H11SCN](2-) anion in THF at 20 degreesC affords the {[(o-C6F4Hg)(3)](B12H11SCN)}(2-) (4) and {[(o-C6F4Hg)(3)](2)(B12H11SCN)}(2-) (5) complexes. Complex 5 was isolated as the tetrabutylammonium salt. X-ray diffraction analysis showed that this complex has a bent-sandwich structure in which the [B12H11SCN](2-) anion is located between the planes of two molecules 1 and is coordinated to both these molecules through B-H-Hg bridges and S-Hg bonds. The stability constants of complexes 4 and 5 in THF (20degrees C, which were determined from the IR spectroscopic data, are 16 L mol(-1) and 992 L-2 mol(-2), respectively.
