Diaqua-bis-(hydrogen tartrato)copper(II) dihydrate
Summary
This study details the crystal structure of a copper(II) hydrogen tartrate complex. The copper ion exhibits distorted octahedral geometry, forming a 3D network via hydrogen bonds.
Area of Science:
- Inorganic Chemistry
- Crystallography
- Coordination Chemistry
Background:
- Copper(II) complexes are vital in catalysis and biological systems.
- Tartrate ligands offer versatile coordination modes.
- Understanding metal-organic structures informs material science.
Purpose of the Study:
- To elucidate the crystal structure and coordination environment of a novel copper(II) hydrogen tartrate complex.
- To investigate the intermolecular interactions governing the solid-state architecture.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of coordination geometry and hydrogen bonding patterns.
Main Results:
- The complex [Cu(C(4)H(5)O(6))(2)(H(2)O)(2)]·2H(2)O features a central Cu(II) ion on an inversion center.
- A distorted octahedral coordination geometry around the copper ion was observed, with equatorial positions occupied by oxygen atoms from two hydrogen tartrate ligands and axial positions by water molecules.
- Intermolecular O-H⋯O and C-H⋯O hydrogen bonds were identified, establishing a three-dimensional network in the crystal lattice.
Conclusions:
- The study provides a detailed structural characterization of a copper(II) hydrogen tartrate complex.
- The observed hydrogen bonding network highlights the importance of non-covalent interactions in stabilizing crystal structures.
- This structural insight contributes to the broader understanding of metal-organic frameworks and coordination compounds.

03:34Ionic Compounds: Formulas and Nomenclature
An element composed of atoms that readily lose electrons (a metal) can react with an element composed of atoms that readily gain electrons (a nonmetal) to produce ions through complete electron transfer. The compound formed by this transfer is stabilized by the electrostatic attractions (ionic bonds) between the oppositely charged ions.
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...
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.

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,...

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.

01:18Aromatic Hydrocarbon Cations: Structural Overview
Cycloheptatriene is a neutral monocyclic unsaturated hydrocarbon that consists of an odd number of carbon atoms and an intervening sp3 carbon in the ring. The three double bonds in the ring correspond to 6 π electrons, which is a Huckel number, and therefore satisfies the criteria of 4n + 2 π electrons. However, the intervening sp3 carbon disrupts the continuous overlap of p orbitals. As a result, cycloheptatriene is not aromatic.
