Bis{μ-2-[bis-(pyridin-2-yl)methyl-idene]hydrazinecarbothio-amidato}bis-[bromido-copper(II)] methanol disolvate
Abstract:
In the centrosymmetric binuclear title compound, [Cu(2)Br(2)(C(12)H(10)N(5)S)(2)]·2CH(3)OH, the Cu(II) ion adopts a slightly dis-torted square-pyramidal coordination geometry. The hydrazine carbothio-amide moiety and one of the pyridyl rings together adopt an almost planar arrangement, with a maximum deviation of 0.052 (4) Å for the C atom of the thio-urea moiety. There are two mol-ecules of methanol solvent per complex in the asymmetric unit. The nonconventional intra-molecular C-H⋯Br hydrogen bonds make the mol-ecule more rigid, whereas the conventional N-H⋯N and O-H⋯Br inter-molecular hydrogen-bonding inter-actions, supported with N-H⋯π inter-actions, establish a supra-molecular linkage among the mol-ecules in the crystal. An intermolecular C-H⋯O inter-action is also present.

Aldehydes and Ketones with Water: Hydrate Formation
The formation of hydrates is a reversible reaction. Hydrate formation is influenced by steric and electronic factors accompanying the alkyl substituents on the carbonyl group: The rate of hydrate formation increases with a decrease in the number of alkyl groups attached to the carbonyl carbon. Hence,...
Acid Halides to Ketones: Gilman Reagent
As shown below, the mechanism proceeds in two steps. First, one of the alkyl groups of the reagent acts as a nucleophile and attacks the acyl carbon of the acid chloride to form a tetrahedral intermediate. This is followed by the reformation of the carbon–oxygen double...
