Jahn Teller Effect

A new lithium vanadium fluoride Li2VF6 was prepared by reacting lithium fluoride LiF with vanadium tetrafluoride VF4 in a monel capsule at 500 °C. The crystal structure has been determined by means of powder X-ray diffraction. Trirutile-type dilithium hexafluorovanadate(IV) crystallizes in the tetragonal space group P42/mnmwith lattice parameters a=459.99(1), b=459:99(1), c=896.64(2) pm. The presence of a Jahn-Teller effect is discussed.

Octahedral Distortion

The new compound Sr2Cu3O4Cl3 was prepared in melts of SrCl2. A single crystal X-ray examination (a = 546.2, c =1259.1 pm, space group D174h-I 4/mmm) shows that the octahedral distortion of the [Cu3O4Cl2]4--network cannot be explained only by the JAHN-TELLER effect.

Alder Adduct

The structure of the compound obtained on heating the naturally occurring clerodane furanoditerpene (1) had been formulated as (2) on the basis of spectroscopic studies. A single-crystal X-ray diffraction study on the dihydro derivative of (2) has confirmed this and provides support for the stereochemistry previously assigned to (1) on the basis of chemical evidence.
