Elemental Analyses

The true identity of the diethyl ether adduct of tungsten(IV) chloride, WCl4(Et2O) x , has been in doubt since 1985. Initially postulated as the bis-adduct, WCl4(Et2O)2, questions arose when elemental analyses were more in line with a mono-ether adduct, viz. WCl4(Et2O). It was proposed that this was due to the thermal instability of the bis-adduct. Here, we report the room-temperature X-ray crystal structure and Hirshfeld surface characteristics of trans-tetrachloridobis(diethyl ether)tungsten(IV), trans-WCl4(Et2O)2 or trans-[WCl4(C4H10O)2]. The compound crystallizes, with half of the molecule in the asymmetric unit, in the centrosymmetric space group P21/n. The W—O distance is 2.070 (2) Å, while the W—Cl distances are 2.3586 (10) and 2.3554 (10) Å.

Cubane Cluster

The thermally highly unstable diethyl ether solvate of lithium chloride was crystallised and its crystal structure determined. It consists of a cubic cluster of the composition Li4Cl4 with each of the four Li atoms coordinated to a molecule of diethyl ether.

Reaction of bromobis(polyfluorophenyl)thallium(III) compounds, R2TlBr (R = C6F5, p-HC6F4, m-HC6F4 or 3,5-H2C6F3) and (C6F5)2TlOH, with copper powder in boiling 1,4-dioxan (diox) or diethyl ether gave the corresponding tris(polyfluorophenyl)thallium(III) compounds, which were isolated as the complexes R3Tl,diox. By contrast, the derivatives R2TlBr (R = o- HC6F4, 3,6-H2C6F3 or Ph) failed to react, and (C6F5)2TlBr was decomposed by copper powder in boiling toluene yielding decafluorobiphenyl. Formation of tris(polyfluorophenyl)thallium(III) compounds is considered to occur via polyfluorophenylcopper(I) intermediates. Treatment of (C6F5)2TlBr with pentafluorophenylcopper in dioxan gave (C6F5)3Tl,diox. The new bromobis-(polyfluorophenyl)thallium(III) compounds, R2TIBr (R = p-HC6F4, m-HC6F4, o-HC6F4, 3,5-H2C6F3 or 3,6- H2C6F3), were prepared by reaction of thallic chloride with the appropriate Grignard reagents.
