Group 13 elements fluorides

An analytical perturbation theory of the Fermi-contact contributions to reduced spin-spin coupling constants has been extended to planar trigonal and tetrahedral main group element fluorides and to octahedral fluorides. ... 

The fluondes of mam group elements are widely applied in organic chemistry as catalysts for a wide variety of reactions Ionic fluorides of group 1 and group 2...

Main-group elements X such as monovalent F, divalent O, and trivalent N are expected to form families of transition-metal compounds MX (M—F fluorides, M=0 oxides, M=N nitrides) that are analogous to the corresponding p-block compounds. In this section we wish to compare the geometries and NBO descriptors of transition-metal halides, oxides, and nitrides briefly with the isovalent hydrocarbon species (that is, we compare fluorides with hydrides or alkyls, oxides with alkylidenes, and nitrides with alkylidynes). However, these substitutions also bring in other important electronic variations whose effects will now be considered. 

Similar to other rare-earths, thulium has a single oxidation state of +3. A general formula for the positive ion of thulium and the elements found in group 7 (fluorides) with a negative ion is expressed as follows ... 

Some fluorides of the main group elements, however, will be discussed here in so far as they represent important structure types. As for the general chemistry of inorganic fluorine compounds the reader is referred to a review by Simons 288) and, restricted to main group elements, to a very recent one by Kemmitt and Sharp (188). 

Considering the influence of electronic configurations on crystal structures it may be asked, whether certain structure t5rpes are restricted to fluorine compounds of the transition elements. Apart from the structure types distorted by the Jahn-Teller effect such a limitation is not obvious at all. On the contrary quite a number of structure prototypes are represented by compounds of the main group elements. Bonding thus must be similar in both, main group and transition element fluorides, at least as for the factors that influence crystal structmes. 

The aim of this article is to summarize the preparations and chemical properties of the presently known oxide fluorides of the main-group elements. We have not included physical properties except to mention those which are novel or of special interest, particularly structural properties.
