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 TiFTi and TiNMe2Ti 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 TiF(bridging) 2.00(2) and 2.06(2), TiF (terminal) 1.77(2), TiN(bridging) 2.14(3) and 2.19(3), TiN(terminal) 1.99(30) A. The structure has been refined to R = 0.077 for 231 visually estimated unique reflections.
