Description

Structure of the complex (n-Bu4N)4[Re6Se8(CN)4Br2]·4H2O, where n-Bu = normal butyl, was determined by the method of X-ray diffraction analysis. Parameters of monoclinic unit cell of the complex are as follows: a = 12.697(2), b = 16.614(2), c = 23.009(4) A, β=96.840(10) deg, sp.gr. P21/c, Z = 2, dcalcld. = 2.105 g/cm3. It is shown that octahedral anion [Re6(μ-Se)8(CN)4Br2]4- contains cluster nucleus Re6Se8 of typical structure with 4 cyanogroups located in the cluster equatorial plane. Interatomic distances in the cluster anions are equal to, respectively: Re-Re(mean) 2.6230 A, Re-Se(mean) 2.515 A, Re-Br 2.589(3) A, Re-C 2.02-2.09 A

Abstract (Russian)

Методом рентгеноструктурного анализа определено строение комплекса (n-Bu4N)4[Re6Se8(CN)4Br2]·4H2O, где n-Bu = нормальный бутил. Параметры моноклинной элементарной ячейки комплекса составили: a=12.697(2), b = 16.614(2), c = 23.009(4) A, β = 96.840(10) град, пр.гр. P21/c, Z = 2, dвыч. = 2.105 г/см3. Показано, что октаэдрический анион [Re6(μ-Se)8(CN)4Br2]4- содержит кластерное ядро Re6Se8 обычного строения с 4-мя цианогруппами, расположенными в экваториальной плоскости кластера. Межатомные расстояния в кластерном анионе равны соответственно: Re-Re(среднее) 2.6230 A, Re-Se(среднее) 2.515 A, Re-Br 2.589(3) A, Re-C 2.02-2.09 A
