Bis(2-methyl-4-nitro-anilinium) tetra-chloridomercurate(II)
Abstract:
The title compound, (C(7)H(9)N(2)O(2))(2)[HgCl(4)], self-assembles into cationic organic bilayers containing the 2-methyl-4-nitro-anilinium cations, sandwiched between anionic inorganic layers built up by the distorted tetra-hedral [HgCl(4)](2-) groups. The organic sheets are inter-linked through weak C-H⋯O hydrogen bonds, while they inter-act with the anionic part via strong charge-assisted N(+)-H⋯Cl-Hg hydrogen bonds. The [HgCl(4)](2-) anions are bis-ected by a mirror plane passing through the metal and two of the chloride ions.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...

Preparation of Acid Anhydrides
The carboxylate ion acts as a nucleophile that attacks the carbonyl carbon of the acid chloride to form a tetrahedral intermediate. Subsequently, the re-formation of the carbonyl group with the loss of the chloride ion as a leaving group leads to the formation of an acid...
Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...
