( Lauri Vaska, E. M. Sloane, J. W. DiLuzio ) In the absence of direct evidence to the contrary, decomposition of solvent alcohol and coordination of its fragments to the metal were not considered, following the above heretofore-accepted assumption in preparative coordination chemistry.

In chemistry, a coordination complex or metal complex, consists of an atom or ion ( usually metallic ), and a surrounding array of bound molecules or anions, that are in turn known as ligands or complexing agents.

As applied to coordination chemistry, this meaning has evolved.

When studying inorganic compounds, one often encounters parts of the different classes of inorganic chemistry ( an organometallic compound is characterized by its coordination chemistry, and may show interesting solid state properties ).

Its enolate is a common ligand in coordination chemistry.

Raw meat packed in a carbon monoxide atmosphere also shows this same pink " smoke ring " due to the same coordination chemistry.

He did pioneering research on the hydrides of boron and silicon, coordination chemistry, mercury, and mercury poisoning.

He was also influential in coordination chemistry.

Acetate is considered a relatively weak ligand in coordination chemistry because it can only form monodentate complexes.

Active site coordination chemistry of the cytochrome c peroxidase Asp235Ala variant: Spectroscopic and functional characterization.

In coordination chemistry, associative substitution proceeds via a similar mechanism as S < sub > N </ sub > 2.

Azides can be used as sources of the nitrido function in the coordination chemistry of late transition metals, loss of N < sub > 2 </ sub > from terminal azide complexes can thus facilitate the formation of unusual oxidation states ( see high-valent iron ).

* Pyridine, a common monodentate ligand in coordination chemistry, abbreviated as ' py '

A large class of compounds discussed in inorganic chemistry textbooks are coordination compounds.

When interacting with enzymes and other proteins Mg < sup > 2 +</ sup > may bind using inner or outer sphere coordination, to either alter the conformation of the enzyme or take part in the chemistry of the catalytic reaction.

Imines are common ligands in coordination chemistry.

# In organometallic chemistry, an unsaturated complex has fewer than 18 valence electrons and thus is susceptible to oxidative addition or coordination of an additional ligand.

More thorough knowledge of basic theories is required, and often there are questions on less-emphasized portions of normal high school chemistry curricula, such as organic chemistry and coordination chemistry.

In 2003, chemist Fraser Stoddart and coworkers at UCLA utilised coordination chemistry to construct a set of rings in one step from 18 components.

Also called the " caesium chloride structure ", this structural motif is composed of a primitive cubic lattice with a two-atom basis, each with an eightfold coordination ; the chloride atoms lie upon the lattice points at the edges of the cube, while the caesium atoms lie in the holes in the center of the cubes.

In general, the vertical hierarchy structure, a relic of Soviet times, has led to poor coordination and duplication of effort among environmental protection agencies.

In very high-pressure situations, silicon will be six-fold or octahderal coordination, such as in the perovskite structure or the quartz polymorph stishovite ( SiO < sub > 2 </ sub >).

Pyroxenes have a general structure formula of XY ( Si < sub > 2 </ sub > O < sub > 6 </ sub >), where X is an octahedral site, while Y can vary in coordination number from six to eight.

On 21 August 1974, the Whitlam Government appointed Justice Robert Hope to conduct a Royal Commission into the structure of security and intelligence services, the nature and scope of the intelligence required and the machinery for ministerial control, direction and coordination of the security services.

In July 2002, the European Commission also established the European Regulators Group for Electronic Communications Networks and Services ; creating, for the first time, a formal structure for interaction and coordination between the European Commission and regulators in all EU Member States to ensure consistent application of European legislation.

The electronic structure of a coordination complex can be described in terms of the set of ligands each donating a pair of electrons to a metal centre.

Key highlights of his tenure as Deputy Assistant Secretary of Defense for Europe and NATO Policy ( 2001 – 2005 ) include the expansion of NATO membership in 2004, the consolidation and reconfiguration of the Alliance ’ s command structure, the standing up of the NATO Response Force and the coordination of European military contributions to U. S .- and NATO-led operations in Iraq, Afghanistan and the Balkans.

Idealized structure of a compound with trigonal planar coordination geometry.

He envisaged the role of the National Security Council to be one of policy coordination and research, and reorganized the NSC structure to ensure that the NSC Adviser would be only one of many players in the foreign policy process.

These rings are not always perfectly symmetrical due to a variety of effects, including strain induced by the bonding between units that are needed to produce the overall structure, or coordination of some of the oxygen atoms of the rings to cations within the structure.
