Zinc compounds are chemical compounds containing the element zinc which is a member of the group 12 of the periodic table. The oxidation state of zinc in most compounds is the group oxidation state of +2. Zinc may be classified as a post-transition main group element with zinc(II). Zinc compounds are noteworthy for their nondescript appearance ...

Zinc(I) compounds are very rare. The [Zn 2] 2+ ion is implicated by the formation of a yellow diamagnetic glass by dissolving metallic zinc in molten ZnCl 2. [61] The [Zn 2] 2+ core would be analogous to the [Hg 2] 2+ cation present in mercury(I) compounds. The diamagnetic nature of the ion confirms its dimeric structure.
Phthalocyanine (H 2 Pc) is a large, aromatic, macrocyclic, organic compound with the formula (C 8 H 4 N 2) 4 H 2 and is of theoretical or specialized interest in chemical dyes and photoelectricity. It is composed of four isoindole units [ a ] linked by a ring of nitrogen atoms.
Katsarosite is a rarely occurring mineral from the mineral class of organic compounds with the chemical composition Zn(C 2 O 4)·2H 2 O and is therefore a water-containing zinc(II) oxalate or the zinc salt of oxalic acid. Katsarosite is categorized in the humboldtine group as the Zn analogue of humboldtine (Fe(C 2 O 4)·2H 2 O). It is the ...
The English Pronouncing Dictionary (EPD) was created by the British phonetician Daniel Jones and was first published in 1917. [1] It originally comprised over 50,000 headwords listed in their spelling form, each of which was given one or more pronunciations transcribed using a set of phonemic symbols based on a standard accent.
2 (η 5-C 5 Me 5) 2 Zn + Et 2 Zn → (η 5-C 5 Me 5) 2 Zn 2 + 2 (η 5-C 5 Me 5)ZnEt + hydrocarbon(s) The analogous reaction of zincocene (Zn(C 5 H 5) 2) with diethylzinc gives (η 5-C 5 H 5)ZnEt. [4] Therefore, the stabilizing effect of the methyl groups on the cyclopentadienyl rings is of great importance in the formation of decamethydizincocene.
A simple example is [NH 4] 2 [ZnCl 4] (ammonium tetrachlorozincate). [1] Zincates are anionic zinc complexes. Related to the preparation of Lucas' reagent, tetrachlorozincates are often generated by combining hydrochloric acid and zinc chloride. A related anion is [Zn 2 Cl 6] 2−, in which again Zn(II) adopts a tetrahedral geometry. [2]
