Summary
This study details the crystal structure of a palladium complex, [PdCl(2)(C(12)H(8)N(2))]. The research highlights the complex
Area of Science:
- Inorganic Chemistry
- Crystallography
- Coordination Chemistry
Background:
- Palladium complexes are vital in catalysis and materials science.
- Understanding the solid-state structure of metal complexes informs their properties.
- 1,10-phenanthroline is a common chelating ligand in coordination chemistry.
Purpose of the Study:
- To elucidate the crystal structure of the palladium(II) complex, [PdCl(2)(1,10-phenanthroline)].
- To investigate intermolecular interactions in the solid state.
- To characterize the coordination environment of the palladium ion.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of bond lengths, bond angles, and intermolecular distances.
- Identification of non-covalent interactions such as π-π stacking and C-H⋯Cl interactions.
Main Results:
- The palladium(II) ion exhibits a four-coordinated, slightly distorted square-planar geometry.
- The complex forms columns along the c-axis due to intermolecular palladium-palladium interactions (4.8340 Å).
- Significant π-π interactions between adjacent phenanthroline rings (3.680 Å centroid-centroid) and weak C-H⋯Cl interactions were observed.
Conclusions:
- The crystal structure reveals a well-defined square-planar coordination geometry for palladium.
- Intermolecular π-π stacking and C-H⋯Cl interactions play a role in stabilizing the crystal lattice.
- The findings contribute to the understanding of structure-property relationships in palladium complexes.

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...
02:51Metal-Ligand Bonds
The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

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...
01:20Diazonium Group Substitution with Halogens and Cyanide: Sandmeyer and Schiemann Reactions
Arenediazonium substitution reactions occur when the diazonium group is substituted by various functional groups such as halides, hydroxyl, nitrile, etc. For instance, arenediazonium salts react with copper(I) salts of chloride, bromide, or cyanide to form corresponding aryl chlorides, bromides, and nitriles. These reactions are named Sandmeyer reactions. Although the mechanism of this reaction is complicated, as illustrated in Figure 1, they are believed to progress via an aryl copper...
01:07Ladder Diagrams: Complexation Equilibria
Ladder diagrams are useful for evaluating equilibria involving metal-ligand complexes. The vertical scale of the ladder diagram represents the concentration of unreacted or free ligand, pL. The horizontal lines on the scale depict the log of stepwise formation constants for metal-ligand complexes and indicate the dominant species in all the regions.
