Arginase from kiwifruit: properties and seasonal variation
(S I R publishing, 1997)The in vitro activity of arginase (EC 3.5.3.1) was investigated in youngest-mature leaves and roots (1-3 mm diameter) of kiwifruit vines (Actinidia deliciosa var. deliciosa) during an annual growth cycle, and enzyme from ... -
Arylstibonic acids [H₈(RSb)₁₂O₂₈]; precursors to organometallic isopolyoxostibonates [Na₂H₉(RSb)₁₂O₃₀]-, (R = aryl).
(Royal Society of Chemistry, 2009)Electrospray ionisation mass spectrometry shows that arylstibonic acids, RSbO₃H₂, give rise to oxo-bridged clusters derived from [H₈(RSb)₁₂O₂₈] which act as inorganic crown ligands towards Na+ cations; structure determination ... -
Isopolyoxometalates derived from arylstibonic acids with "reverse-Keggin ion" structures based on [M(RSb) ₁₂O ₂₈] cores, M = Co(ii) or Zn(ii).
(The Royal Society of Chemistry., 2012)The preparations and structures are described of four new polyoxostibonates, [Co(p-MeC ₆H ₄Sb) ₁₂O ₂₈{Co(H ₂O) ₃} ₄]Cl ₂₋ 6H ₂O, [Co(p-ClC ₆H ₄Sb)₁₂O ₂₈{Co(H ₂O) ₃} ₄]Cl₂₋ 22H ₂O, (PhCH ₂NMe ₃) ₂[Zn(p-ClC ₆H ₄Sb) ₁₂O ₂₈Zn ... -
Isopolyoxometalates of Antimony: Arylstibonic Acids [H₈ (RSb)₁₂O₂₈] and Derived Dodecanuclear Polyoxostibonates [M₂H10−x(RSb)₁₂O₃₀]x−, M = Na or K
(American Chemical Society, 2010)Electrospray ionization mass spectrometry shows arylstibonic acids, p-XC₆H₄SbO₃H₂ (X = methyl, nitro, or chloro), and 1-naphthylstibonic acid exist in MeCN as dodecanuclear aggregates [H₈(RSb)₁₂O₂₈]. With KOH or NaOH these ... -
New Sb₁₂ and Sb₁₄ Polyoxometalate Frameworks Derived from Arylstibonic Acids: [LiH₃(p-MeC₆H₄Sb)₁₂O₂₈]⁴⁻ and [BaH₁₀(p-MeC₆H₄Sb)₁₄O₃₄]
(American Chemistry Society, 2011)The lithium salt of p-tolylstibonic acid contains the anion [LiH₃(p-MeC₆H₄Sb)₁₂O₂₈]⁴⁻, in which the Li⁺ is fully enclosed within an {Sb₁₂O₂₈} cage with γ Keggin ion geometry; the idealized overall formula is Li₅[LiH₃(p-M ...
