Oxotitan-Addukte mit Dimethylsulfoxid: [TiO(OSMe2)5]Cl2 und [Ti4O6(OSMe2)12]Cl4 · 5Me2SO · 1/2 H2O / Oxotitanium Compounds with Dimethylsulfoxide: [TiO(OSMe2)5]Cl2 and [Ti4O6(OSMe2)12]Cl4 · 5Me2SO · 1/2 H2O

Abstract: Titanyl-5 DMSO-Dichloride. Tetratitaniumhexoxo-12 DMSO-Tetrachloride, Crystal Structure While TiCl4 and Na2S4 react in in the presence of PPh4Cl in dichloromethane to yield (PPh4)2[TiSCl4]-2CH2Cl2, we obtained fTi40 6(0SMe2)i2]Cl4-5Me2S 0T /2H 20 (1) from the same reactants in dimethylsulfoxide. Compound 1 is only stable in the presence of dimethylsulfoxide. The crystal structure determination at 153 K shows the presence of cations having an adamantane-like Ti40 64+ skeleton with three Me2SO molecules coordina… Show more

“…In Figure 1a, three peaks are shown, the first two peaks represent the Ti O and Ti O RDFs obtained for the first shell, peaking at distances of 1.57 and 2.10 Å, respectively. The experimentally determined value for the Ti O bond distance obtained by X-ray crystallography of different complexes of the Ti(IV) ion [23][24][25] varies from 1.64 to 1.68 Å, which is ∼0.1 Å longer Fig. 1a).…”

“…[4] Its structure is related to the moreelaborate oxo complexes, for example, [Ti 4 F 12 O 6 ] 4À , [5] and [Ti 4 O 6 (OSMe 2 ) 12 ] 4+ . [6] The related [Ti 2 F 9 ] À ion was claimed to exist in solution, [7] and the salts M[Ti 2 F 9 ] (M = Cs, NF 4 ) have been reported, [8] although their X-ray crystal structures were not determined. We predict, on the basis of estimates of the corresponding energetics, that all monocation salts, with the possible exception of those having small cations, favor [Ti 2 [16] This difference may be because [18]crown-6…”

“…[Ti 4 F 18 ] 2− (Figure 1) has overall T d symmetry and is the second example of such a binary [M 4 X 18 ] 2− cage (M=metal, X=halogen), the first being [W 4 F 18 ] 2− 4. Its structure is related to the more‐elaborate oxo complexes, for example, [Ti 4 F 12 O 6 ] 4− ,5 and [Ti 4 O 6 (OSMe 2 ) 12 ] 4+ 6. The related [Ti 2 F 9 ] − ion was claimed to exist in solution,7 and the salts M[Ti 2 F 9 ] (M=Cs, NF 4 ) have been reported,8 although their X‐ray crystal structures were not determined.…”
