  2. C2-Symmetric ligands - Wikipedia

    en.wikipedia.org/wiki/C2-Symmetric_ligands

    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 ...

  3. Denticity - Wikipedia

    en.wikipedia.org/wiki/Denticity

    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 ...

  4. Dimethylglyoxime - Wikipedia

    en.wikipedia.org/wiki/Dimethylglyoxime

    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 ...

  5. Tetradentate ligand - Wikipedia

    en.wikipedia.org/wiki/Tetradentate_ligand

    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 ...

  9. Tridentate ligand - Wikipedia

    en.wikipedia.org/wiki/Tridentate_ligand

    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 ...
