The negative charge that is left after deprotonation of the carboxyl group is delocalized between the two electronegative oxygen atoms in a resonance structure. If the R group is an electron-withdrawing group (such as –CF 3), the basicity of the carboxylate will be further weakened. [1]: 264–5
Structure of hydrated nickel acetate. Transition metal carboxylate complexes are coordination complexes with carboxylate (RCO 2 −) ligands. Reflecting the diversity of carboxylic acids, the inventory of metal carboxylates is large. Many are useful commercially, and many have attracted intense scholarly scrutiny.
Structure of a carboxylic acid Carboxylate anion 3D structure of a carboxylic acid. In organic chemistry, a carboxylic acid is an organic acid that contains a carboxyl group (−C(=O)−OH) [1] attached to an R-group.
The carboxylate molecule in this case in the large BTB molecule (BTB = benzene-1,3,5-tribenzoic acid). This large yet rigid tri-carboxylate unit connects to the cluster in the same manner as in the MOF-5 structure but as there are three carboxylate units and a triangular geometry, this produces a more spherical porous cage structure rather than ...
Structure of 1,2,3,4-butanetetracarboxylate, a low molecular weight polycarboxylate. Polycarboxylates are organic compounds with several carboxylic acid groups. Butane-1,2,3,4-tetracarboxylate is one example. Often, polycarboxylate refers to linear polymers with a high molecular mass (M r ≤ 100 000) and with many carboxylate groups.
In organic chemistry, butyl is a four-carbon alkyl radical or substituent group with general chemical formula −C 4 H 9, derived from either of the two isomers (n-butane and isobutane) of butane.
Its molecular structure consists of a central azo functional group, RN=NR, flanked by two ethyl ester groups. This orange-red liquid is a valuable reagent but also quite dangerous and explodes upon heating.
