Mdssbaucr studies on 57Fe isolated in solid ammonia and ammonillxenon mixtures were performed at 4.2 and 77 K. They give direct evidence that atomic iron reacts only with one ammonia molcculc forming FcNH3 which is stable in an ammo& matrix up to 77 K. In addition a compound is formed which is attri

✦ Synopsis
The MGssbauer spectrum of the [Fe(NR3)6]'+ cation consists of a single narrow line at room temperature _ This musud effect is attributed to the existence of a dynamic Jahn-Teller distortion which inverts the t2g orb%& very rapidly such that the time-averaged qvdence is zero. The observed splitting of 1500 cm-1 in the 5~g State i? the electronic spectrxm of [Fe(NH$ tion. The Small ferrous quadrupole splittings in [Fe11(CH3CN) I [ d ICI2 is consistent with this explma-eCl4j2 and [Fe(C&CN)6] [FeCl&, and the three line Massbauer spectrum of [Fe(NH&]C12 at 8OgK are also discussed.

The 99Ru nuclear quadrupole interaction in pRuC13 can be related to the large irigonal distortion at the ruthenium site. The ratio of the quadrupole moments has been determined to be Qe/Qg = +3.06 + 0.10, and it is confirmed that Qe and Qg arc both positive.
