Mössbauer spectra, structure, and bonding in iron carbonyl derivatives
Autor: N. N. Greenwood, R. Greatrex
Publikováno v: Discuss. Faraday Soc.. 47:126-135
The Mossbauer spectra of the mono-, di-, tri- and tetra-nuclear iron carbonyl anions and carbonyl hydride anions are reported and compared with the known spectra of the neutral binary carbonyls. Increase in anionic charge in the sequence 0, –1, –

A Mössbauer-effect study of the bonding in compounds containing tin–transition-metal bonds
Autor: B. A. Goodman, N. N. Greenwood, R. Greatrex
Publikováno v: J. Chem. Soc. A. :1868-1872
The sign of the quadrupole coupling constant, e2qQ, has been determined for 119Sn in the following six compounds: [Mn(CO)5SnCl3], [Mn(CO)5SnCl2Me], [Fe(π-C5H5)(CO)2SnCl3], [Fe(π-C5H5)(CO)2SnBu3], [{Fe(π-C5H5)(CO)2}2SnCl2], and [{Fe(π-C5H5)(CO)2}2

The asymmetric Mössbauer spectrum of di-iron enneacarbonyl
Autor: R. Greatrex, T. C. Gibb, Norman N. Greenwood
Publikováno v: J. Chem. Soc. A. :890-894
The previously reported asymmetry in the Mossbauer spectrum of Fe2(CO)9 has been re-investigated and found to be due solely to preferential orientation in the material. There is no evidence for a substantial anisotropy of the recoil-free fraction. Th

Mössbauer spectra of some tellurium complexes
Autor: Norman N. Greenwood, T. C. Gibb, R. Greatrex, A. C. Sarma
Publikováno v: J. Chem. Soc. A. :212-217
Tellurium-125 Mossbauer spectra are reported for various tellurates and tellurites, and for a series of compounds of TeCl62–, TeBr62–, Tel62–, and TeF5– with various cations. The chemical isomer shift is found to be characteristic of the onio

The Mössbauer spectra of some phosphorus- and sulphur-bridged derivatives of di-iron enneacarbonyl
Autor: T. C. Gibb, Norman N. Greenwood, R. Greatrex, D. T. Thompson
Publikováno v: J. Chem. Soc. A. :1663-1666
Mossbauer spectra are reported for a series of phosphorus- and sulphur-bridged derivatives of Fe2(CO)9. Substitution of a terminal carbonyl group by triethylphosphine has only a small effect on the Mossbauer parameters and these are also rather insen
