CuCl 2 reacts with HCl or other chloride sources to form complex ions: the red [CuCl 3] − (found in potassium trichloridocuprate(II) K[CuCl 3]) (it is a dimer in reality, [Cu 2 Cl 6] 2−, a couple of tetrahedrons that share an edge), and the green or yellow [CuCl 4] 2− (found in potassium tetrachloridocuprate(II) K 2 [CuCl 4]).
Chloroform, [10] or trichloromethane (often abbreviated as TCM), is an organochloride with the formula C H Cl 3 and a common solvent. It is a volatile , colorless, sweet-smelling, dense liquid produced on a large scale as a precursor to refrigerants and PTFE . [ 11 ]
[1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.
[10] [11] The phase diagram for the anhydrous system KCl / CuCl 2 shows potassium trichloridocuprate KCuCl 3 as a congruently-melting compound, but not K 2 CuCl 4. [12] The dihydrate decomposes on heating above 93 °C to KCl, KCuCl 3 and water. [13] [14] The doubts were put to rest when successful dehydration was achieved by T. J. Nolan and ...

[MnCl 6] 2−: dark red (t 2g) 3 (e g) 1: octahedral Mn-Cl distance = 2.28 Å K + salt [14]) salt is isostructural with K 2 PtCl 6 [MnCl 6] 3−: brown [3] (t 2g) 3 (e g) 1: octahedral [10] [3] [Mn 2 Cl 6] 2−: yellow-green (e g) 2 (t 2g) 3: bitetrahedral Mn-Cl(terminal) bond length = 2.24 Å Mn-Cl(terminal) bond length = 2.39 Å [15] (PPN ...
[2] KCuO 2 was discovered first in 1952 by V. K. Wahl and W. Klemm, they synthesized this compound by heating copper(II) oxide and potassium superoxide in an atmosphere of oxygen. [3] 2 KO 2 + 2 CuO → 2 KCuO 2 + O 2. It can also be synthesized by heating potassium superoxide and copper powder: [4] KO 2 + Cu → KCuO 2. KCuO 2 reacts with the ...
Trichlorobenzene (TCB) may refer to any of three isomeric chlorinated derivatives of benzene with the molecular formula C 6 H 3 Cl 3. They differ by the positions of the chlorine atoms around the ring: 1,2,3-Trichlorobenzene; 1,2,4-Trichlorobenzene; 1,3,5-Trichlorobenzene
