Abstract

Crystals of di-mu-bromido-bis[tetrabromidotantalum(+V)], (+TaBr5)(2), were obtained by recrystallization at 773 K. A first crystal structure study of (+TaBr5)(2) was reported by Rolsten [J. Am. Chem. Soc. (1958), 80, 2952-2953], who analysed the powder diffraction pattern and came to the conclusion that it crystallizes isotypically with (NbBr5)(2) in a primitive orthorhombic cell. These findings are not in agreement with our current results of a monoclinic C-centred structure. (TaBr5)(2) is isotypic with alpha-(+NbCl5)(2). The crystal structure contains [TaBr6] octahedra sharing common edges forming [TaBr5](2) dimers. Two crystallographically independent dimers with symmetries m and 2/m and Ta center dot center dot center dot Ta distances of 4.1574 (11) and 4.1551 (15) angstrom, respectively, are present in the structure.
