Coordination complex - Wikipedia
WEBA coordination complex is a chemical compound consisting of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents.

WEBAn example of a coordination complex is hexaaquo cobalt dichloride, Co (H 2 O) 6 Cl 2. This compound contains a Co 2+ ion. This electrophilic metal ion is coordinated by six nucleophilic water ligands. Because the water molecules are neutral, the complex still has a 2+ charge overall.
Coordination Complexes and Ligands - Division of Chemical …
WEBCoordination compounds, such as the FeCl 4-ion and CrCl 3 6 NH 3, are called such because they contain ions or molecules linked, or coordinated, to a transition metal. They are also known as complex ions or coordination complexes because they are Lewis acid-base complexes.

WEBJun 30, 2023 · Complexes or coordination compounds are molecules that posess a metal center that is bound to ligands (atoms, ions, or molecules that donate electrons to the metal). These complexes can be neutral or charged. When the complex is charged, it is stabilized by neighboring counter-ions.

What Is A Coordination Compound? - Purdue University
WEBA coordination complex is the product of a Lewis acid-base reaction in which neutral molecules or anions (called ligands) bond to a central metal atom (or ion) by coordinate covalent bonds. Ligands are Lewis bases - they contain at least one pair of electrons to donate to a metal atom/ion.
Coordination compound - Ligands, Metal Ions, Bonding
WEBThe general class of coordination compounds—or complexes, as they are sometimes called—is extensive and diverse. The substances in the class may be composed of electrically neutral molecules or of positively or negatively charged species (ions).
Coordination compound - Ligands, Metal Ions, Bonding
WEBThe coordination number of a particular complex is determined by the relative sizes of the metal atom and the ligands, by spatial (steric) constraints governing the shapes (conformations) of polydentate ligands, and by electronic factors, most notably the electronic configuration of the metal ion.

WEBMar 19, 2023 · In a typical coordination complex (or simply complex), a central metal atom or ion is chemically bonded to several other components. These complexes are quite common and have many important uses. Hemoglobin and myoglobin that carry oxygen within our bodies are two important biological molecules that contain a coordination complex (the heme).
WEBcoordination compounds. Complexes. Ligands. The molecules or ions coordinating to the metal are the ligands. They are usually anions or polar molecules.
