Summary
Crystal structures of two phenylethylammonium hexachloridostannate(IV) isomers reveal alternating organic-inorganic layers. These layers interact through N-H...Cl hydrogen bonding, forming a 2D sheet in the inorganic layer.
Area of Science:
- Crystal engineering
- Coordination chemistry
- Supramolecular chemistry
Background:
- Hexachloridostannate(IV) compounds are known for their diverse structural motifs.
- Organic ammonium cations can influence the assembly of inorganic anions in crystal structures.
- Hydrogen bonding plays a crucial role in directing the formation of extended networks.
Purpose of the Study:
- To elucidate the crystal structures of bis(1-phenylethylammonium) hexachloridostannate(IV) and bis(2-phenylethylammonium) hexachloridostannate(IV).
- To investigate the role of N-H...Cl hydrogen bonding in the assembly of these compounds.
- To characterize the layered structures formed by the organic and inorganic components.
Main Methods:
- Single-crystal X-ray diffraction analysis.
- Structural comparison of the two isomers.
- Analysis of hydrogen bonding interactions.
Main Results:
- Both compounds, (C(8)H(12)N)(2)[SnCl(6)], exhibit alternating layers of organic cations and inorganic [SnCl(6)](2-) anions.
- An extended two-dimensional hydrogen-bonded sheet is present within the inorganic layer.
- N-H...Cl hydrogen bonds mediate the interactions between the organic and inorganic layers.
- The tin atom in the 1-phenylethylammonium salt is located on an inversion center.
Conclusions:
- The crystal structures demonstrate a clear layered arrangement driven by hydrogen bonding.
- The phenylethylammonium cation isomers dictate specific packing arrangements and hydrogen bonding networks.
- These findings contribute to understanding the structure-property relationships in metal-organic hybrid materials.

02:54Coordination Compounds and Nomenclature
In most main group element compounds, the valence electrons of the isolated atoms combine to form chemical bonds that satisfy the octet rule. For instance, the four valence electrons of carbon overlap with electrons from four hydrogen atoms to form CH4. The one valence electron leaves sodium and adds to the seven valence electrons of chlorine to form the ionic formula unit NaCl (Figure 1a). Transition metals do not normally bond in this fashion. They primarily form coordinate covalent bonds, a...
03:46Qualitative Analysis
For solutions containing mixtures of different cations, the identity of each cation can be determined by qualitative analysis. This technique involves a series of selective precipitations with different chemical reagents, each reaction producing a characteristic precipitate for a specific group of cations. Metal ions within a group are further separated by varying the pH, heating the mixture to redissolve a precipitate, or adding other reagents to form complex ions.
For instance, group IV...

01:22EDTA: Chemistry and Properties
Polydentate ligands are most widely used in complexometric titrations because they form more stable complexes with the metal ions than mono- or bidentate ligands due to the chelate effect. Examples of polydentate ligands are ethylenediaminetetraacetic acid (EDTA), crown ethers, and cryptands. The most important feature of optimal polydentate ligands is the ability to form 1:1 complexes in a single-step process. Amino carboxylic acid derivatives are frequently used as complexing agents. EDTA is...
02:42Valence Bond Theory
Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

Isomerism in Complexes
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...

01:12Nomenclature of Secondary and Tertiary Amines
The secondary and tertiary amines are derivatives of ammonia, where two and three of its hydrogens are replaced by alkyl groups, respectively. Secondary and tertiary amines can be symmetrical with identical alkyl groups attached to the nitrogen atom or unsymmetrical when more than one type of alkyl group is present. The standard nomenclature of secondary and tertiary amines is similar to the names given to the primary amines. They are generally named alkylamines. As depicted in Figure 1, for...
