No replacement of the second chlorine atom by an enolate group occurred even when a large excess of lithium enolate was used. The reactivity of the zinc enolates suggests that they contain both zinc carbon and zinc oxygen bonds. They are assumed to have a cyclic structure which resembles that...

The basic structure of zinc sulphate consists of one zinc atom bonded to four oxygen atoms and one sulfur atom. This compound is highly soluble in water. Zinc sulphate is considered to be non-toxic and safe for general use. However, it can cause irritation to the skin and eyes, and ...

Soils contaminated with zinc through the mining of zinc-containing ores, refining, or where zinc-containing sludge is used as fertilizer, can contain several grams of zinc per kilogram of dry soil.[87] Levels of zinc in excess of 500 ppm in soil interfere with the ability of plants to abso...
Because semiconductors in the zinc blende structure have a different atom at each basis site, the atoms at the dislocation core may belong to either the group III or group V species. By convention, the resulting dislocations are referred to as β and α dislocations, respectively. Greater uncert...
Zinc(I) compounds are rare and need bulky ligands to stabilize the low oxidation state. Most zinc(I) compounds contain formally the [Zn2]2+ core, which is analogous to the [Hg2]2+ dimeric cation present in mercury(I) compounds. The diamagnetic nature of the ion confirms its dimeric struc...
Fig. 3.1.The crystal structure of zinc oxide. Note the type of site which can accommodate an extra zinc atom. (3.1)2ZnO⇌2Zn+O2 which effectively removes some oxygen atoms from the lattice. The excess zinc atoms (not ions, notice) then dissolve in the remaining solid oxide and occupy ...
, both of which contain 0.05% (v/v) formic acid (detection wavelength: 210 and 254 nm). LC-HR-ESI-MS was performed similarly on waters UPLC (Waters Corp., USA) coupled with an AB TripleTOF 5600plus mass spectrometer system (AB SCIEX, USA)....
(copper zinc carbonate hydroxide) and many related minerals that are zinc-containing. Natural ZLM's can also occur wherein anionic layer species such as clay-type minerals (e.g., phyllosilicates) contain ion-exchanged zinc gallery ions. All of these natural materials can also be obtained ...
