Diaqua-(2,2'-bipyridine-κN,N')bis-(perchlorato-κO)copper(II)
Summary
This study details a copper compound with a distorted octahedral geometry, revealing a long copper-oxygen bond. Intermolecular hydrogen bonds and pi-pi stacking stabilize the crystal structure.
Area of Science:
- Inorganic Chemistry
- Crystallography
- Coordination Chemistry
Background:
- Jahn-Teller distortion is a key phenomenon in coordination chemistry affecting metal ion geometry.
- Understanding crystal packing and intermolecular forces is crucial for predicting material properties.
Purpose of the Study:
- To characterize the crystal structure and coordination environment of a novel copper(II) perchlorate complex.
- To investigate the intermolecular interactions, including hydrogen bonding and pi-pi stacking, within the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of bond distances, angles, and intermolecular contacts was performed.
Main Results:
- The central copper ion (Cu) displays a Jahn-Teller distorted octahedral geometry with a (4+1+1) coordination mode.
- A notably long Cu-O bond distance of 2.5058(12) Å was observed towards a perchlorate oxygen.
- Intermolecular O-H⋯O hydrogen bonds and π-π stacking interactions (3.7848(9)–4.4231(9) Å) were identified, forming layered structures.
Conclusions:
- The unique coordination geometry and intermolecular forces dictate the layered crystal packing.
- The findings contribute to the understanding of Jahn-Teller effects in copper complexes and crystal engineering principles.

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.
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...

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.

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...
02:42Valence 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...
01:07Ladder 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.
