The title compound has been synthesized as a green solid by the reaction of MeCl2 SiNHSiMe3 and Ti(NMe2)4 in CH2Cl2. The crystal structure was determined by single crystal X-ray methods at room temperature (C2/c, a = 1825,7(4), b = 909,9(2), c = 1116,1(2) pm, β = 125,09(3)°, Z = 4,R1= 0,047, wR2 = 0,147) to be an ionic salt [H2NMe2]+[(Me2NH)2TiCl4]- . The central titanium(III) atom of the anion is bound to four Cl atoms and weakly coordinated by two Me2NH ligands.
