Abstract
Abstract The crystal structure of [(Me2N)2TiF24 has been determined by single-crystal X-ray diffraction. The crystals are tetragonal, I 4 , a = b = 11.313(5), c = 12.862(4) A, Z = 2. The titanium atoms display a distorted octahedral coordination and are linked by TiFTi and TiNMe2Ti bridges to form a tetramer, which possesses a crystallographic inverse tetrad axis at its centre. One fluorine and one dimethylamino group do not participate in the bridging. The principal bond lenghts are TiF(bridging) 2.00(2) and 2.06(2), TiF (terminal) 1.77(2), TiN(bridging) 2.14(3) and 2.19(3), TiN(terminal) 1.99(30) A. The structure has been refined to R = 0.077 for 231 visually estimated unique reflections.
