Mixed Titanium–Hafnium Chloridometallate Complexes

Solubility Behaviour of TiCl4, ZrCl4, and HfCl4 in Chloroaluminate Ionic Liquids

“…For example, they can be prepared directly from the chloride salt mixed with corresponding amounts of a chloride source. [19b,19c,21–22] These structures can be considered as solid‐state structures of the corresponding metal chlorides with additional stabilising chloride ligands 22a. However, the structures crystallised with [BMIM] + and [PhNMe 3 ] + cations were not measured yet.…”

Synthesis and characterisation of ionic liquids based on 1-butyl-3-methylimidazolium chloride and MCl4, M = Hf and Zr

“…These data for R = 0.5 agree with the structure [C 1 C 4 Im][MCl 5 ] and not [C 1 C 4 Im] 2 [M 2 Cl 10 ], as previously reported. 35,36 For R = 0.67, as well as the isotopic pattern corresponding to [MCl 5 ] -(m/z = 266.9 (Zr) and 356.9 (Hf), the isotopic pattern corresponding to [M 2 Cl 9 ]m/z = 500.…”

A Periodic Walk through a Series of First‐Row, Oxido‐Bridged, Heterodimetallic Molecules: Synthesis and Structure

“…[12,13] Here, we report the synthesis of a series of first-row transition-metal heterodimetallic molecules (Ti=O→M) where the structural and electrochemical properties can be controlled through the identity of M. To date, only a few examples of unsupported oxido-bridged Ti-O-M heterodimetallic compounds are known. [5,6,[13][14][15][16] Molecules of this type were pioneered by Goedken and co-workers, who reported the synthesis of various heterodimetallic complexes formed through the use of dative interactions from a titanium terminal oxo complex [OTi [17][18][19] Such complexes, along with other similar complexes, may be ideal for exploring charge-transfer kinetics through a dative linkage, rather than a covalent bond. …”
