Host–Guest and Photophysical Behavior of Ti8L12 Cube with Encapsulated [Ti(H2O)6] Species

“…XPS analysis indicates that it is dominated by Ti IV ions, forming an intra‐molecular charge balance by cationic [Ti IV (H 2 O) 6 ] 4+ guest and anionic [Ti IV 8 L 12 ] 4− host. It is worth noting that the Ti IV −O distances in the [Ti(H 2 O) 6 ] species of PTC‐98 are 1.993, 1.996, and 2.005 Å, respectively, all of which are clearly shorter than the reported Ti III −O distances (2.018–2.046 Å), but longer than the Ti IV −O OH distances (∼1.85 Å) in the reported [Ti IV (OH) 6 )] 2− …”

“…The inner cavity of the Ti 8 L 12 cube in PTC-97 provides an opportunity to investigate its application in supramolecular hostguest chemistry.I ndeed, when the above reactionm edium was changed to am ixture of acetic acid and isopropyl alcohol, an unprecedented [Ti(H 2 O) 6 [40] but longert han the Ti IV ÀO OH distances (~1.85 )i n the reported [Ti IV (OH) 6 )] 2À . [41] From the above structural analysis, we believe that in PTC-98 the [Ti(H 2 O) 6 6 ], preventing it from escaping and further hydrolyzing (Figure 1b); iii)Host-guest interaction:m ost importantly,t here are abundant intra-cube hydrogen bonds to stabilizet he [Ti(H 2 O) 6 ] species.…”

Novel Organically Templated Mixed-Valent Titanium Phosphates with Open Framework Structures: Hydrothermal Synthesis and Characterization

“…Although the compound is phosphorus-rich (Ti : The distance to the water molecules, 2.039(6) A, is very similar to Ti-H 2 0 distances in other TiIII compounds, from 2.018(5) to 2.046(6) A in a hexaaquatitanium(III) trication [9], and at 2.028(5)…”

Synthesis and characterization of first row transition metal p-toluenesulfonate complexes and chains

“…Examples include halo- [1,4,[123][124][125][126][127][128], methane- [1,[4][5][6][129][130][131][132][133][134][135], trifluoromethyl- [1,[4][5][6], and various arylsulfonate [1,[4][5][6]122,132,133, analogues. The higher solubility and rapid substitution kinetics are often exploited to afford clean reaction products and higher chemical yields [1,4,169,[183][184][185][186][187][188][189][190].…”
