Popis:	The N-alkylated azatitanatranes N ( C H Z C H ~ N R ) ~ T ~ C I [R = Me (l), Et (2), i-Pr (3)] have been prepared and 1 and 3 structurally characterized by X-ray crystallography: 1, orthorhombic, Pmna, a = 1 1.293(3) A, b = 1 1.977(3) A, c = 9.722(3) A, V = 1314.96 A3, Z = 4, R = 0.0629; 3, cubic, Pa3, a = 15.928(4) A, V = 4040.95 A3, Z = 8, R = 0.0792. The halide ligand in 2 and 3 could be replaced by more labile ligands by chloride abstraction using the appropriate silver salts. A single-crystal X-ray structure analysis of N ( C H ~ C H Z N E ~ ) ~ T ~ O S O ~ C F ~ (4), the first azatrane-triflate to be reported, was carried out. Crystal data for 4: triclinic, Pf (No. 2), a = 16.039(4) A, b = 16.473(4) A, c = 8.954(3) A, a = 105.75’, 0 = 106.17(2)’, y = 107.54(2)’, V = 1996.33 A3, Z = 4, R = 0.0842. The titanium amido complexes reported here may find use as building blocks in more complex structural arrays.
