49Ti, NMR

Ti NMR spectra have been obtained for a number of perovskite and ilmenite ATiOs compounds. 

Ti 49Ti solid-state NMR spectra of Ti02 nanoparticles have been reported. The corresponding NMR spectra have been simulated by 

Table 11. Summary of solid-state NMR interaction parameters for 49Ti

Blinc et a/.177,178 performed 47Ti(/— 5/2) and 49Ti(/= 7/2) quadrupole-perturbed NMR experiments with very high-quality single crystal of BaTiCV The authors observed that in the paraelectric cubic phase T> Tc, the narrow central 1/2) transition lines are surrounded by a broad 

Stable dianionic derivatives of the Ti carbonyl complex [Ti(CO)6]2 have been synthesized, isolated, and characterized.1045 The [Ti(CO)6]2 ion was obtained via reductive carbonylation of Ti(CO)3(DMPE)2 or TiCl4(DME) by KCioHg in the presence of a crown ether or cryptand.1045 An octahedral environment about Ti in [K(cryptand 2.2.2)l2[Ti(CO)6] was confirmed both in solution by the observation of a septet resonance in the 49Ti NMR spectrum for the 13CO complex and cry stallographically.1046 Related complexes with weakly solvated alkali metal cations readily decomposed.1047
