A coordination entity is an arrangement consisting of a metal ion that acts as a centre, to which neutral or anionic ligands are covalently bonded. A coordination entity is enclosed inside square brackets. It may be charged or neutral, depending upon the complex. The metal inside the coordination entity has a fixed coordination number (which […]

Coordination compounds are a class of chemical compounds in which there is a central metal atom that is bonded to several ligands simultaneously. The metal acts as a Lewis acid and the ligands as Lewis bases.  Ligands are the molecules or atoms that contain a lone pair of electrons that can be donated to the

A coordination complex comprises a core atom or ion called the coordination centre, which is usually metallic, and a surrounding array of bonded molecules or ions called ligands or complexing agents. Many metal-containing compounds, particularly those containing transition metals (elements in the d-block of the Periodic Table, such as titanium), are coordination complexes. A dative

A coordinate compound (or complex) contains one or more coordinate bonds, which are links between two electrons in which one of the atoms donates both electrons. To put it another way, it’s a chemical with a coordination complex. Except for alloys, coordination compounds include most metal complexes or compounds. Haemoglobin, chlorophyll, dyes, pigments, vitamin B12,

A coordination complex is made up of a core atom or ion, which is usually metallic and is referred to as the coordination centre, and an array of attached molecules or ions, which are referred to as ligands or complexing agents. Coordination complexes are found in many metal-containing compounds, particularly those incorporating transition metals. [Cu(NH3)4]

A coordination or complex compound is one in which two or more anions or neutral molecules are coordinated to a metal atom or ion. In most cases, a coordination compound contains one or more complex ions. For example, K₄[Fe(CN)₆] is made up of a complex ion, [Fe(CN)₆]⁴⁺.  A ligand is a chemical or ionic species

A coordination compound comes under a class of chemical compounds in which central atoms and central ions are bonded to several ligands simultaneously.  The central atoms and central ions act as Lewis acid and the ligands as Lewis bases. Ligands are the molecules or atoms that contain a lone pair of electrons which can be

Groups 3–12 elements are located in the d-block of the periodic table, where the d orbitals gradually fill during each of the four long periods. The d–block is bordered by the s– and p–blocks in the centre region of the periodic table. Because of their position between s– and p– block components, the d-block elements

Calcium carbonate (CaCO3) is an inorganic chemical compound made up of calcium, carbon, and oxygen. Under normal temperatures and pressures, this diatomic chemical looks like a fine white powder and is mostly tasteless and odourless. Physical description Calcium carbonate is a white, odourless powder and can even take the form of colourless crystals. Practically insoluble

Borazine is an inorganic aromatic compound formed as an azo-derivative of boron. Borazine is also named ‘borazole’ as it contains azole groups in its heterocyclic ring structure. This cyclic structure of the borazine exemplifies the inorganic benzene in chemistry. It is not the same as benzene, though it highly resembles it in its structure and
