Oxalate also forms coordination compounds where it is sometimes abbreviated as ox. It is commonly encountered as a bidentate ligand. When the oxalate chelates to a single metal center, it always adopts the planar conformation. As a bidentate ligand, it forms a 5-membered MC 2 O 2 ring. An illustrative complex is potassium ferrioxalate, K 3 [Fe ...

While a horse figures in some allusions by later writers, the ox is the preferred beast in Renaissance emblem books. It appears as such in a Latin poem by Hieronymus Osius (1564), although the accompanying illustration shows both an ox and an ass and the dog there, as in Steinhöwel, carries a bone clenched between its teeth.

Transition metal oxalate complexes are coordination complexes with oxalate (C 2 O 42−) ligands. Some are useful commercially, but the topic has attracted regular scholarly scrutiny. Oxalate (C 2 O 42-) is a kind of dicarboxylate ligand. [1] As a small, symmetrical dinegative ion, oxalate commonly forms five-membered MO 2 C 2 chelate rings.
oxo-, ox/i: addition of oxygen: oxy-sharp, acid, acute; oxygen: borrowed from French oxygène (originally principe oxigine, 'acidifying principle', referring to oxygen's role in the formation of acids, from Greek ὀξύς (oxús), sharp, pointed + γένος (génos), birth) oxytocin, oxygenated, oxycodone

Oxalate oxidase. In enzymology, an oxalate oxidase ( EC 1.2.3.4) is an oxalate degrading enzyme that catalyzes the chemical reaction : The 3 substrates of this enzyme are oxalate, O 2, and H +, whereas its two products are CO 2 and H 2 O 2 . This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo ...
Oxalatonickelate. The oxalatonickelates are a class of compounds that contain nickel complexed by oxalate groups. They form a series of double salts, and include clusters with multiple nickel atoms. Since oxalate functions as a bidentate ligand it can satisfy two coordinate positions around the nickel atom, or it can bridge two nickel atoms ...
