Abstract:
The structure of the title compound, {(C(5)H(5)ClN)(2)[Hg(3)Cl(8)]}(n), consists of 4-chloropyridinium cations and one-dimensional [Hg(3)Cl(8)](2-) anion chains. There are two coordination environments for Hg(II) in the inorganic chain. The first is a distorted tetrahedral geometry made up of an HgCl(2) unit with two Cl(-) anion bridges, while the second is an octahedral coordination geometry consisting of an HgCl(2) unit and four chloride-anion bridges. This gives rise to a novel three-layer centrosymmetric polymer. Finally, the three-dimensional network comes about through the many C-H···Cl and N-H···Cl hydrogen bonds that link the organic and inorganic layers.

01:20Amides to Amines: LiAlH4 Reduction
Amide reduction requires two equivalents of the reducing agent, acting as a source of hydride ions. As shown in the figure, the reaction is initiated with a nucleophilic attack by the hydride ion at the carbonyl carbon to form a tetrahedral intermediate.
00:55Nitriles to Amines: LiAlH4 Reduction
As shown below, the mechanism involves three steps. Firstly, the hydride ion acting as a nucleophile attacks the nitrile carbon to form an anion. In the second step, a second equivalent of the hydride ion attacks the anion to...
01:19Acid Halides to Alcohols: LiAlH4 Reduction
The mechanism proceeds in three steps. First, the nucleophilic hydride ion attacks the carbonyl carbon of the acid halide to form a tetrahedral intermediate. Next, the carbonyl group is re-formed, and the halide ion departs as a leaving group, generating an aldehyde. A second nucleophilic attack by the hydride yields an alkoxide ion, which, upon protonation, gives a primary alcohol as...
