“…Interestingly treatment of 1-4 with nitromethane, acetone, chloroform, and dichloromethane rapidly precipitates fine M(OTs) 2 powders suggesting these may initially solubilize and rapidly eliminate coordinated DMF ligands. This behavior confirms that the DMF ligands are substitutionally labile under a variety of conditions [133,172,173,[181][182][183][184][185][186][187]196,197].…”

“…Structural reports describing sulfate and sulfonate derivatives are commonplace in the chemical literature. Among these are the Tutton [16,, halosulfonates [123][124][125][126][127][128], methane- [129][130][131][132][133][134][135][136], and arylsulfonate salts [133,135,[166][167][168][169][170][171][172][173][174][175][176][177][178][179][180][181][182][183]. These generally adopt very complicated structures owing to extensive hydrogen bonding interactions between anions and water molecules present.…”

The preparation, structures, and spectroscopic properties of several molecular complexes and a one dimensional chain are described. Onedimensional {trans-Cr II (DMF)2(OTs)2}n (1) chain and mononuclear complexes of trans-[M II (OTs)2(DMF)4] (M II = Fe, 2; Co, 3) and [Ni II (DMF)6][OTs]2 (4) stoichiometry are readily obtained from DMF/Et2O solutions containing the parent anhydrous tosylate salts. A hydrated analogue, trans-[Fe II (OTs)2(OH2)2(DMF)2] (5), is obtained in minor quantities from solutions containing 2. Electronic spectra indicate all of the complexes adopt octahedral geometries in dimethylformamide solution. Room temperature susceptibility data indicates that high spin electronic configurations are preferred for 1 (S = 2), 2 (S = 2), and 3 (S = 3 /2) while 4 adopts an S = 1 spin ground state. The solubility properties of the salts are also described.

The chapter presents the advances in the chemistry of hypervalent derivatives of selenium and tellurium that have emerged in recent years (usually after 1998). These are based on the inclusion of the discussed compounds into particular subsections, arising from the N‐Ch‐L (A n B m ) coding system, in which N stands for the number of valence electrons associated formally with a central chalcogen atom and L shows the number of ligands (A and B stand for the bonding element). The chapter begins with a brief discussion on the nature of bonding, molecular geometry, basic reactivity and pseudorotation mechanisms in hypervalent selenium and tellurium molecules which can be described as 10‐Ch‐4 and 10‐Ch‐5 and 12‐Ch‐6 species. Next, the unstable hypervalent selenium and tellurium structures detected as reactive intermediates are discussed. The remaining part of the chapter is devoted to the presentation of the chemistry of stable compounds. The isolable derivatives are presented in the following order: selenuranes and telluranes, 10‐Ch‐5 and 12‐Ch‐5 species, 10‐Ch‐6 complexes of perchalcogenuranes with Lewis bases, 12‐Ch‐6 perchalcogenuranes, 12‐Ch‐5 perchalcogenuranes, and 2N‐Ch‐N charged pertelluranes (Ch = Te, N > 6).
