| Abstract [eng] |
The compound [C6H5CH2(CH3)3N]2[SeBr6]·CH3CN (1) was prepared from elemental selenium and bromine, and benzyltrimethylammonium bromide. The crystal structure of 1 has been determined by X-ray methods and refined to R = 0.0554 and 0.1072 for 1772 and 2591 reflections, respectively. The crystals were monoclinic, space group was I 2/a with Z = 4 and a = 15.064(3), b = 9.2617(19), c = 22.161(4) Å, b = 93.91(3)°. The [SeBr6]2–·octahedron of 1 is centrosymmetric with Se-Br = 2.5445(11), 2.5756(11), 2.5740(12) Å and Br-Se-Br = 90.34(4), 90.56(4), 90.07(3)°. It has been confirmed that the individual Se-Br bond lengths in hexabromoselenate(IV) anions vary within a wide range, whereas the total length of the linear Br-Se-Br bonding systems in these ions is almost constant, which is in accordance with the three-centrefour electron bond model. |
