The structures of tellurium(IV) halides in the gas phase and as solvated molecules.

The structures of molecular tellurium tetrafluoride and tellurium tetrachloride were determined by a combination of gas-phase electron diffraction, mass spectrometry and quantum chemical calculations. The combined GED/MS experiments showed no evidence of decomposition of TeF(4) and TeCl(4). No ions of oligomeric (dimeric, trimeric, etc.

[Te(CN)4] versus [Te(CN)3(micro-CN)](n).

Solvent molecules have a great influence on the structure and stability of tellurium tetracyanide; whereas Te(CN)4 x (diglyme)(2) contains monomeric Te(CN)4 units, [Te(CN)3(micro-CN) x diglyme](n) is a coordination polymer.
