Examples of coordination complex in the following topics:
-
- In chemistry, a coordination or metal complex consists of an atom or ion (usually metallic) and a surrounding array of bound molecules or anions known as ligands or complexing agents.
- Many metal-containing compounds consist of coordination complexes.
- These complexes are called chelate complexes, the formation of which is called chelation, complexation, and coordination.
- A common reaction between coordination complexes involving ligands are electron transfers.
- This complex, PtCl2(NH3)2, is an anti-tumor drug and an example of a coordination complex.
-
- Coordination complexes are found in many biomolecules, especially as essential ingredients for the active site of enzymes.
- Coordination complexes (also called coordination compounds) and transition metals are widespread in nature.
- While there are other biologically relevant molecules that also contain metals, coordination complexes contain a central metal ion and are important in many biological processes.
- Metalloenzymes contain a metal ion bound to the protein with one labile coordination site.
- The fourth coordination site is occupied by a water molecule.
-
- Ligands create a complex when forming coordinate bonds with transition metals ions; the transition metal ion acts as a Lewis acid, and the ligand acts as a Lewis base.
- The number of coordinate bonds is known as the complex's coordination number.
- The product is known as a complex ion, and the study of these ions is known as coordination chemistry.
- One coordination chemistry's applications is using Lewis bases to modify the activity and selectivity of metal catalysts in order to create useful metal-ligand complexes in biochemistry and medicine.
- Examples of several metals (V, Mn, Re, Fe, Ir) in coordination complexes with various ligands.
-
- The electronic configuration of some metal complexes gives them important properties, such as color in coordination compounds.
- Many of the properties of metal complexes are dictated by their electronic structures.
- It can explain complexes in which the interactions are covalent.
- Changing the metal or the ligand can change the color of the coordination complex.
- Reactions starting from NiCl2·6H2O can be used to form a variety of nickel coordination complexes because the H2O ligands are rapidly displaced by ammonia, amines, thioethers, thiolates, and organophosphines.
-
- Complex numbers can be represented in polar coordinates using the formula $a+bi=re^{i\theta}$.
- The previous geometric idea where the number $z=a+bi$ is associated with the point $(a,b)$ on the usual $xy$-coordinate system is called rectangular coordinates.
- The alternative way to picture things is called polar coordinates.
- In polar coordinates, the parameters are $r$ and $\phi$.
- Explain how to represent complex numbers in polar coordinates and why it is useful to do so
-
- The coordination number determines the number of ligands attached to the central ion and the overall shape of the complex.
- Typically the chemistry of complexes is dominated by interactions between s and p molecular orbitals of the ligands and the d orbitals of the metal ions.
- In coordination chemistry, a ligand is an ion or molecule (functional group) that binds to a central metal atom to form a coordination complex.
- For example, trans-spanning ligands are bidentate ligands that can span coordination positions on opposite sides of a coordination complex.
- Calculate the coordination number of the metal in a coordination complex.
-
- When two or more types of ligands are coordinated to an octahedral metal center, the complex can exist as isomers.
- In an octahedral complex, this degeneracy is lifted.
- Rearrangements where the relative stereochemistry of the ligands change within the coordination sphere
- Many reactions of octahedral transition metal complexes occur in water.
- Discuss the degeneracy of the d orbitals in an octahedral metal complex.
-
- Some curves have a simple expression in polar coordinates, whereas they would be very complex to represent in Cartesian coordinates.
- To graph in the rectangular coordinate system we construct a table of $x$ and $y$ values.
- To graph in the polar coordinate system we construct a table of $r$ and $\theta$ values.
- Although the graphs look complex, a simple polar equation generates the pattern.
- Complex graphs generated by the simple polar formulas that generate rose curves:$r=a\:\cos n\theta$ and $r=a\:\sin n\theta$ where $a≠0$.
-
- Chelating agents are ligands for metals that bind via multiple atoms, thus taking up several coordination sites on the metal.
- Chelation is the formation or presence of two or more separate coordinate bonds between a polydentate (multiple bonded) ligand and a single central atom.
- Chelate complexes are contrasted with coordination complexes composed of monodentate ligands, which form only one bond with the central atom.
- Chelating agents, unlike the other ligands in coordination compounds, bind via multiple atoms in the ligand molecule, not just one.
- In (1), the bidentate ligand ethylenediamine forms a chelate complex with the copper ion.

- Increasing coordination helps organizations to maintain efficient operations through communication and control.
- Coordination is simply the managerial ability to maintain operations and ensure they are properly integrated with one another; therefore, increasing coordination is closely related to improving managerial skills.
- The management team must pay special attention to issues related to coordination and governance and be able to improve upon coordination through effective management.
- While this list is long and complex, the underlying concept is relatively simple: managers should strengthen communication across all facets of the organization to increase the level of integration between each moving part.
- In practice, coordination involves a delicate balance between centralization and decentralization.
