Description

Crystalline 1:2 adduct of aquatrifluoroboron and triphenylphosphine oxide: 1/2[BF3(Ho)] · Ph3Po(I) was prepared and studied by the method of X-ray diffraction analysis. The crystals are rhombic, space group Fdd2, a = 32.283, b = 20.162, c = 10.191 A, Z = 16. Molecule of [BF3(H2O)] is statistically disordered in reference to axis 2; population of all its atomic positions equals 0.5. Boron atom has a distorted tetrahedral coordination with B-O(w) donor-acceptor bond, its length being 1.568 (9) A. The B-F bond lengths fall within the range 1.378(8)-1.399(9) A

Abstract (Russian)

Получен и методом рентгеноструктурного анализа изучен кристаллический аддукт 1:2 акватрифторбора и трифенилфосфиноксида 1/2[BF3(Ho)] · Ph3Po(I). Кристаллы ромбические, пр. гр. Fdd2, a = 32.283, b = 20.162, c=10.191 A, Z = 16. Молекула [BF3(H2O)] статистически разупорядочена относительно оси 2; заселенности позиций всех ее атомов равны 0.5. Атом бора имеет искаженную тетраэдрическую координацию с донорно-акцепторной связью B-O(w), длина которой составляет 1.568 (9) A. Длины связи B-F лежат в интервале 1.378(8)-1.399(9) A
