Summary
This study details the crystal structure of a zinc chloride compound with 6-methyl-2,2′-bipyridine. The molecule features a distorted tetrahedral zinc(II) center and exhibits significant π-π stacking interactions between aromatic rings.
Area of Science:
- Coordination Chemistry
- Crystal Engineering
- Supramolecular Chemistry
Background:
- Bipyridine ligands are crucial in coordination chemistry, influencing the properties of metal complexes.
- Understanding the solid-state interactions of metal-organic compounds is key to designing new materials.
Purpose of the Study:
- To elucidate the crystal structure of the title compound, [ZnCl2(C11H10N2)].
- To investigate the coordination environment around the zinc(II) ion.
- To identify and analyze intermolecular interactions, specifically π-π contacts.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of bond lengths, angles, and intermolecular distances was performed.
Main Results:
- The zinc(II) atom adopts a distorted tetrahedral geometry, coordinated by two nitrogen atoms from the 6-methyl-2,2'-bipyridine ligand and two chloride ions.
- Significant π-π stacking interactions were observed between the aromatic rings of the bipyridine ligand and adjacent molecules.
- Centroid-centroid distances for these π-π contacts were measured at 3.685(3) Å and 3.757(3) Å.
Conclusions:
- The crystal structure reveals a discrete four-coordinate zinc(II) complex.
- The observed π-π interactions play a role in the supramolecular assembly of the crystal lattice.
- This structural information contributes to the understanding of metal-bipyridine complexes and their solid-state behavior.

02:57Coordination Number and Geometry
For transition metal complexes, the coordination number determines the geometry around the central metal ion. Table 1 compares coordination numbers to molecular geometry. The most common structures of the complexes in coordination compounds are octahedral, tetrahedral, and square planar.
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.
The formation constant, K1, for the formation of Cd(NH3)2+ complex from cadmium and ammonia is 3.55 × 102. Log K1 (i.e. pNH3) is 2.55, and...

02:46Crystal Field Theory - Tetrahedral and Square Planar Complexes
Tetrahedral Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...

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...
03:02Colors and Magnetism
Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.

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...
