The Stereochemistry of Sb(III) Halides and Some Related Compounds

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

“…Due to the characteristics of 121 Sb, the electronic structure of Sb compounds can accurately be analyzed by this method. 324 For the aforementioned adduct, 323 a seven-coordinate geometry and stereochemical activity of the Sb III lone pair was proposed; 325 however, the actual structure of the obtained 1 : 1 adducts could not be clarified by that time. Later, Bertazzi et al as well as Levason et al performed a single-crystal XRD analysis of [Sb(tpy)F 3 ], which revealed the expected pseudo-pentagonal-bipyramidal coordination geometry – two F − ligands were located in the plane with the tpy ligand, the third F − ligand was found at an apical site of the structure and the lone pair occupied the seventh position (Fig.…”

The Political Economy ofThe Art of War

“…with a perspective for envisioning alternative approaches and a method for converting their situations to advantage." 75 The parallels to Kirzner's entrepreneur are fairly clear. The unorthodox is an expression of Kirznerian discovery in the sense that the astute commander perceives an opportunity to exploit his environment to his advantage, thus capturing a profit opportunity.…”
