In homogeneous catalysis C2-symmetric ligands refer to ligands that lack mirror symmetry but have C2 symmetry (two-fold rotational symmetry). Such ligands are usually bidentate and are valuable in catalysis. [1] The C2 symmetry of ligands limits the number of possible reaction pathways and thereby increases enantioselectivity, relative to ...
Denticity. In coordination chemistry, denticity (from Latin dentis 'tooth') refers to the number of donor groups in a given ligand that bind to the central metal atom in a coordination complex. [1][2] In many cases, only one atom in the ligand binds to the metal, so the denticity equals one, and the ligand is said to be monodentate (sometimes ...
Dimethylglyoxime is a chemical compound described by the formula CH 3 C (NOH)C (NOH)CH 3. Its abbreviation is dmgH2 for neutral form, and dmgH− for anionic form, where H stands for hydrogen. This colourless solid is the di oxime derivative of the di ketone butane-2,3-dione (also known as diacetyl). DmgH 2 is used in the analysis of palladium ...
Tetradentate ligand. In chemistry, tetradentate ligands are ligands that bind four donor atoms to a central atom to form a coordination complex. This number of donor atoms that bind is called denticity and is a method of classifying ligands. Tetradentate ligands are common in nature in the form of chlorophyll, which has a core ligand called ...
Magnesium is involved in over 300 essential metabolic reactions, including energy production, blood pressure regulation, nerve signal transmission, and muscle contraction (1). Low magnesium levels ...

Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Infobox references. Nickel bis (dimethylglyoximate) is the coordination complex with the formula Ni [ONC (CH 3)C (CH 3)NOH] 2. The compound is a bright red solid. It achieved prominence for its use in the qualitative analysis of ...
Tridentate ligand. A tridentate ligand (or terdentate ligand) is a ligand that has three atoms that can function as donor atoms in a coordination complex. [1] Well-known tridentate ligands include diethylenetriamine with three nitrogen donor atoms, and the iminodiacetate anion which consists of one deprotonated amine nitrogen and a pair of ...
