On the Anomalous Properties of theh¹-Cyclopentadienyltin(IV) Halides

A Diglyme Adduct of Tin(IV) Chloride Formed on Drying Aromatic Solvents by the Benzophenone Ketyl/Potassium Metal Method

“…4 It was noted that addition under nitrogen of freshly distilled tin(IV) chloride to benzene or toluene freshly distilled from potassium and the benzophenone ketyl to which diglyme had been added resulted in the formation of a green-black colored oil. The formation of such an oil by this sequence has not been previously noted.…”

The chemistry of the s- and p-block elements with 2,2′:6′,2′′-terpyridine ligands

“…24a). [232][233][234] Accordingly, the original complex structure, as proposed by 236 The applied spectroscopic technique, which is based on the socalled Mößbauer effect (i.e., the resonant and recoil-free emission/absorption of γ-radiation by certain atomic nuclei), is highly sensitive towards subtle changes in the chemical environment of an appropriate nucleus and can, thus, be utilized to study the coordination geometry of, e.g., Sn IV complexes. Both the isomer shift and the quadrupole splitting gave further evidence for the presence of six-coordinate cations and five-coordinate anions in various complexes.…”

“…Debye et al performed detailed 119 Sn Mößbauer studies on complexes derived from tpy with Me 2 SiCl 2 , Ph 2 SnCl 2 , and n -Bu 2 SnCl 2 ; 235 whereas, Tomaja and Zuckerman accordingly studied the corresponding complexes derived from (η 1 -Cp) 2 SnX 2 (Cp: cyclopentadienyl anion; X = Cl or Br). 236 The applied spectroscopic technique, which is based on the so-called Mößbauer effect ( i.e. , the resonant and recoil-free emission/absorption of γ-radiation by certain atomic nuclei), is highly sensitive towards subtle changes in the chemical environment of an appropriate nucleus and can, thus, be utilized to study the coordination geometry of, e.g.…”
