Coordination chemistry of copperi complexes with bis. Naming coordination compounds department of chemistry. There are several types of the bridges, from which. Copper chemistry the department of chemistry uwi, mona. Copper is also an essential trace nutrient for organisms ranging from bacteria to mammals. A characteristic feature of copper i chemistry is the plasticity of the coordination sphere around it. If the coordination number is 4, the coordination complex is either square planar or tetrahedral. When the coordination number is 6, the complex is octahedral. All journal articles featured in journal of coordination chemistry vol 73 issue 4. Coordination of the ligand with cuoac2 produced a tetranuclear complex.
New insights into the coordination chemistry and molecular. Pdf the coordination chemistry of the copperii, zinc. The chemistry of coordination compounds is an important and challenging area of modern inorganic chemistry. Specific coordination number and geometries depend on metal and number of delectrons 4. Kit mao department of chemistry, washington university st. Geometry of coordination compounds coordination compounds with a coordination number of 2 are linear. The coordination mode of the ligands and the properties of the complexes are found to vary with change in the nuclearity, phosphine ligand structure, counter ion, and solvent. Copper is classed as a transition metal both from its physicochemical properties and its biochemical behavior. Winter, dblock chemistry, oxford chemistry primers, oup, 2001. The charge on the complex ion is also the same as the charge. When the complex is charged, it is stabilized by neighboring counterions.
The coordination number of the central metal ion or atom is the number of donor atoms bonded to it. In modern terminology such compounds are called coordination compounds. For the chapter on copper chemistry from the elsevier text. Coordination compounds are molecules that poses one or multiple metal centers that is bound to ligands atoms, ions, or molecules that donate electrons to the metal. Louis, mo 63 for information or comments on this tutorial, please contact k.
Copper ii in liquid and aqueous ammonia solution configuration in aqueous ammonia solution, but an increase in coordination number from four to five most probably occurs in although the xanes spectra of the three investigated liquid ammonia solution. The tetratopic ligand is prepared in five steps from 4tertbutylphenol. The number of ligands is equal to the coordination number for copper, 4. Hsab theory useful a hard bases stabilize high oxidation states b soft bases stabilize low oxidation. Analysis of smallmolecule copper chemistry generally indicate that cu i binding is thermodynamically favored by the inclusion of more sulfur donors, as opposed to oxygen or nitrogen donors, and by lower coordination numbers.
