We report the first X-ray single crystal structures of hypochlorite (ClO - ) and hypobromite (BrO - ) salts, including hydrated sodium hypochlorite - a staple of the chlorine industry and ubiquitous bleaching and disinfection agent for almost 200 years. The structures, supported by variable-temperature Raman spectroscopy on individual crystals and periodic density-functional theory (DFT) calculations, provide insight into solid-state geometry and supramolecular chemistry of hypohalite ions.

Sodium Hypochlorite Pentahydrate Crystals (NaOCl·5H2O): A Convenient and Environmentally Benign Oxidant for Organic Synthesis

The novel oxidant of sodium hypochlorite pentahydrate (NaOCl·5H2O) crystals is now available for industrial and laboratory use. It is superior to conventional aqueous sodium hypochlorite solutions

Characterisation of the oxo-anions of bromine BrOx–(x= 1–4) by infrared, Raman, nuclear magnetic resonance, and bromine K-edge extended X-ray absorption fine structure techniques

The bromine oxo-anions BrOx–(x= 1–4) have been studied by vibrational and multinuclear n.m.r. spectroscopy and bromine K-edge extended X-ray absorption fine structure (EXAFS) measurements. Raman

X. The Crystal Structure of Sodium Perchlorate, NaClO4

Some time ago Prof. V. M. Goldschmid t received some crystals of NaClOi from Prof. K. F a j a n s in München. Prof. Goldschmidt suggested to me to carry out an X-ray investigation of this compound.

Sodium Chloride Dihydrate Crystals: Morphology, Nucleation, Growth, and Inhibition

Sodium chloride powders have a strong tendency to cake at freezing temperatures, which is caused by the formation of sodium chloride dihydrate solid bridges between the powder particles. Using the

Metal-free mechanochemical oxidations in Ertalyte® jars

Herein, an Ertalyte® jar has been successfully used, for the first time, in a mechanochemical process, safe, inexpensive and performing effectively, especially on the macroscale.

"Bleaching powder" is made by the action of chloride gas on calcium hydroxide, the reaction being essentially: 2Ca(OH)2 + 2Cl2 → Ca(OCl)2 + CaCl2 + 2H2O. The constitution of the solid formed in this

Characterization of dibromine monoxide (Br2O) by bromine K-edge EXAFS and IR spectroscopy

Dark brown dibromine monoxide (Br 2 O) has been prepared by controlled decomposition of BrO 2 and studied by infrared and UV-vis spectroscopy and bromine K-edge EXAFS. Infrared studies of Br 2 O are
