Abstract
The cationic complexes with hexacoordinate silicon(IV), tris [1-oxopyridine -2-olato(1-)]silicon(IV) trifluoromethanesulfonate (4), 4(.)1/2C(5)H(5)NO(2 ), tris[1-oxopyridine-2-olato(1-)]silicon(IV) ethyl sulfate-ethanol (5(.)Et OH), and tris[1-oxopyridine-2-olato(1-)]silicon(IV) isopropyl sulfate (6), were synthesized. The identities of 4, 4(.)1/2C(5)H(5)NO(2), 5(.)EtOH, and 6 were established by elemental analyses (C, H, N, S), mass-spectrometric s tudies (FAB MS) as well as solid-state (Si-29) and solution (H-1, C-13, F-1 9, Si-29) NMR experiments. In addition, 4(.)1/2C(5)H(5)NO(2) was structural ly characterized by single-crystal X-ray diffraction.
