In the crystal structure of the title compound, [Cu(C(2)H(3)O(3))Cl(H(2)O)](n), the Cu(II) ion is five-coordinate in a distorted square-pyramidal geometry. Two O atoms from a chelating glycolate anion, an O atom from a coordinated water mol-ecule and a chloride anion comprise the basal plane. A chloride ion from a neighbouring unit occupies the apical position and these Cu-Cl-Cu bridges link th...
In the title compound, [Zn(C(9)H(6)NO)Cl(C(9)H(7)NO)]·CH(3)OH, the Zn(II) ion is N,O-chelated by both a neutral and a deprotonated quinolin-8-ol ligand, with a chloride ligand in the apical site completing the square-pyramidal coordination geometry. The Zn(II) ion is displaced by 0.586 Å in the direction of the chloride ligand from the atoms forming the square plane. In the crystal, the compone...
The title compound, Ph3(PhCH2)P(+)·Cl(-)·H2O, was obtained unintentionally as the product of an attempted synthesis of a silver di-thio-carbamate complex using benzyl-tri-phenyl-phospho-nium as the counter-ion. The asymmetric unit consists of a phospho-nium cation and a chloride anion, and a water mol-ecule of crystallization. In the crystal, the chloride ion is linked to the water mol-ecule by...
The molecule of the title compound, [IrCl(C7H5NS)(C3H9P)3], is a distorted octa-hedral iridium complex with three PMe3 ligands arranged in a meridional geometry, a chloride ion cis to all three PMe3 groups and the phenyl iso-thio-cyanate ligand bonded in an η(2)-fashion through the C and S atoms. The C atom is trans to the chloride ion and the S atom is responsible for a significant deviation f...
امروزه استفاده از بتن برای ساخت انواع سازه ها و اجزای سازه ای و غیرسازه ای بسیار گسترش یافته و روز به روز نیز بر ابعاد استفاده از آن افزوده می شود. در این راستا، مسیله داوم انواع بتن های مصرفی از ویژگی و اهمیت خاصی برخوردار است. سواحل و جزایر خلیج فارس و دریای عمان، به عنوان مرز ارتباطی کشور با دریای آزاد، و نیز به دلیل منابع نفتی استانهای جنوب و جنوب غربی کشور، بخش عمده ای از مهمترین مناطق صنع...
در چند دهه اخیر مهم ترین توسعه انقلابی در ساخت و اجرای بتن استفاده از بتن های خود تراکم می باشد. استفاده از این بتن ها بدلیل داشتن مزایای فراوان روبه افزایش می باشد لذا شناخت ویژگی ها و مسایل مرتبط با این نوع بتن لازم و ضروری بنظر می رسد. خوردگی ارماتورها در بتن از جمله رایج ترین آسب دیدگی ها در سازه های بتن آرمه موجود در شرایط محیطی خاص می باشد. در این تحقیق تاثیر عیار سیمان بر برخی از پارامت...
A synthetic receptor, with an ability to bind sodium or potassium chloride as a contact ion-pair, is shown to effectively transport either salt across vesicle membranes. Significant transport is observed even when the transporter: phospholipid ratio is as low as 1:2500. Chloride efflux from unilamellar vesicles is monitored using a chloride selective electrode. Mechanistic studies indicate that...
A series of novel 1,2,3-triazolylidene gold(i) chloride complexes have been synthesised and fully characterised. Silver-free methodologies for chloride ion abstraction of these complexes were evaluated for their potential as Au-based catalyst precursors. Using simple potassium salts or MeOTf as chloride scavengers produced metal complexes that catalyse both the regioselective synthesis of oxazo...
Aaronson, I. (1971). Archives of Disease in Childhood, 46, 479. Secondary chloride-losing diarrhoea. Observations on stool electrolytes in infants after bowel surgery. Among 40 infants with postoperative diarrhoea, 3 were found to have a stool chloride concentration in excess of the sum of sodium and potassium ion concentrations. All 3 had had a recent episodof intestinal obstruction and had de...
In the title compound, (C(21)H(22)N)(2)[AuCl(4)]Cl, the Au(III) atom adopts a square-planar coordination geometry defined by four chloride ions. In the crystal structure, inter-molecular N-H⋯Cl hydrogen bonds link the organic cations and the uncoordinated chloride ion.
