Iodate anion

A mixture of dimethyl sulfate with SO is probably dimethyl pyrosulfate [10506-59-9] CH2OSO2OSO2OCH2, and, with chlorobenzene, it yields the 4,4 -dichlorodiphenylsulfone (153). Trivalent rare earths can be separated by a slow release of acid into a solution of rare earth chelated with an ethylenediaminetetraacetic acid agent and iodate anion. As dimethyl sulfate slowly hydrolyzes and pH decreases, each metal is released from the chelate in turn and precipitates as the iodate, resulting in improved separations (154). 

Unexpected uniformities observed in the impact-sensitivities of a group of 22 amminecobalt oxosalts are related to kinetic factors during the initiation process [6], A series of ammine derivatives of cadmium, cobalt, copper, mercury, nickel, platinum and zinc with (mainly) iodate anions was prepared and evaluated as explosives [7], Earlier, ammine and hydrazine derivatives of cadmium, cobalt, copper and nickel with chlorate or perchlorate anions had been evaluated as detonators. Dihydrazinecopper(II) chlorate had exploded when dried at ambient temperature [8],... 

As discussed in Section 3, the EC mechanism is a common electrode reaction route. An example of an EC reaction studied by RDE techniques is (87), the iodide mediated reduction of iodate anions in acidic aqueous media (Beran and Bruckenstein, 1968). Iodide is formed at the electrode surface through reduction of iodine in the aqueous solution.

Figure 16. A depiction of part of the polar, three-dimensional network structure of Np02(103) showing the alignment of the stereochemically active lone pair of electrons on the iodate anions along the c-axis.

Am(I03)3 and Cm(I03)3 are isostructural, crystallizing with the type I Gd(I03)3 structure this stmcture type is known with elements ranging from Ce to Lu (except for Pm) and Y, and is the series of iodate compounds with the most members [77, 79, 85], This stmcture consists of An cations bound by iodate anions to create a three-dimensional architecture. The Am or Cm centers are bound by eight bridging iodate anions to create a distorted, dodecahedral environment around the An. Each AnOs polyhedron is formed by the monodentate coordination of eight iodate anions. 

As is the case with Am(I03)3 and Cm(I03)3, the presence of three distinct iodate ions is also a feature in the Cf(I03)3 system. The I-O bond distances and angles in the iodate anions range from 1.801(15) to 1.825(14) A...
