Heteroleptic Four-Coordinate Tris(oxazolinyl)borato Iron(II) Compounds

Anti-leishmanial activity of heteroleptic organometallic Sb(v) compounds.

In seeking new drugs for the treatment of the parasitic disease Leishmaniasis, an extensive range of organometallic antimony(v) dicarboxylates of the form [SbR3(O2CR')2] have been synthesised, characterised and evaluated. The organometallic moieties (R) in the complexes vary in being Ph, tolyl (o, m or p), or benzyl. The carboxylates are predominantly substituted benzoates with some compounds i...

Steric and electronic influence on photochromic switching of N,C-chelate four-coordinate organoboron compounds.

A four-coordinate organoboron compound B(ppy)Mes(2) (1, ppy=2-phenylpyridyl, Mes=mesityl) was previously found to undergo reversible photochromic switching through the formation/breaking of a C-C bond, accompanied by a dramatic color change from colorless to dark blue. To understand this unusual phenomenon, a series of new four-coordinate boron compounds based on the ppy-chelate ligand and its ...

Hmong Elaborate Expressions are Coordinate Compounds

On exposure to Hmong discourse1 discourse, or that of many other structurally-similar Southeast Asian languages—the speaker of English can hardly help but be impressed by the pervasiveness of parallelism in this discourse tradition. Almost everything seems to be repeated, often in balanced pairs. Of course, parallelism in language is by no means confined to Southeast Asia—as a stylistic device ...

On The Semantics Of English Coordinate Compounds

A four-coordinate Fe(III) porphyrin cation.

Few families of compounds have been as intensely studied as iron porphyrin complexes. In spite of this, a truly four-coordinate Fe(III) porphyrin cation has never before been reported.1 The exceptional electrophilicity of the four-coordinate [FeIII(Porph)]+ cation will even coordinate arene solvent upon crystallization if the counteranion is extremely non-coordinating, as in the work of Reed wi...
