“…The P-P distance [2.252 (2) It is interesting to compare the structures of the two sodium salts [(2-C 4 H 3 S)P] 2 Se 4 Na 2 (1g) and (PhP) 2 Se 4 Na 2 -(thf) 3 . [11] The salts are quite similar, both have an aromatic substituent bonded to phosphorus. In both cases the tetraselenohypodiphosphonate anions are coordinated to sodium ions to form chains throughout the crystal.…”

“…[11] The tetraselenohypodiphosphonate anions can act as chelating ligands coordinating through two selenium atoms bonded either to the same phosphorus atom (A) or to different phosphorus atoms (B) (Figure 3). In addition, a combination of the two coordination modes is also possible.…”

The aim of this paper is to introduce a synthetic concept suitable for the preparation of a broad variety of compounds. The so-called anhydride route (in this article the term anhydride is used for compounds derived from corresponding acids by formal loss of H2O, H2S and H2Se) has so far led to a range of unusual Group 15/16 ligands in oligomeric and polymeric environments. Commonly, reactions of neutral precursor molecules, for example, [{RP(S)(mu-S)}2] (R=4-anisyl) Lawesson's reagent or [{PhP(Se)(mu-Se)}2] Woollins's reagent and metal salts are performed to result in novel coordination compounds in which ligands and metal atoms form coordination oligomers and polymers. An attempt is made to relate the outcome of the investigations to the type of metal used. By relating the strength of ionic interactions, which correspond to metal-donor distances, to phenomena observed in the solid-state structures, an aspect of supraionic chemistry is described. Chemistry of and beyond novel Group 15/16 anions is further discussed using a novel approach in coordination chemistry where the chemical nature of ligands is unknown prior to the experiment despite the use of a range of similar starting materials.

This chapter describes syntheses, structures, and reactions of the compounds with phosphorus‐selenium double bonds and with at least one carbon‐phosphorus single bond and of their heavier congeners. Among them, phosphane selenides have been the most deeply studied and used as Lewis base catalysts, metal ligands, molecular sensors, and stating materials leading to selenium‐containing nanoparticles. The coupling constants between the phosphorus and selenium atoms are informative on the basicity of the phosphanes. Phosphinoselenoic acid chlorides and secondary phosphanes are frequently used precursors to give a range of phosphinoselenoic acid derivatives, whereas selenation of dichlorophosphanes leads to phosphonoselenoic acid dichlorides, which are converted to a variety of acid derivatives. The selenation of phosphinites also gives phosphinoselenoic acid O ‐esters. Stereochemical course of the substitution reaction at P ‐chiral phosphorus center in the substitution reaction has been elucidated. Some reactions of dimers of diselenoxophosphanes such as Woollin's reagent are also shown. The chapter finally describes examples of phosphane tellurides, arsenic, antimony, and bismuth isologues of phosphane selenides, although these are fewer.
