carboxylate

(kär-bŏk′sə-lāt′)
n.
A salt or ester of an organic acid, derived from the carboxyl group. Soaps, which are usually the sodium or potassium salts of fatty acids, are carboxylates.
adj. (-lāt′, -lĭt)
1. Of or relating to a carboxylate.
2. Of or relating to the anionic conjugate base of a carboxylic acid, specifically the CO22- group

car·box·y·late

(kahr-boksi-lāt)
A salt or ester of the carboxylic acid group.

Among the reported structures, organic ligands with carboxylate play an important role in coordination chemistry and can adopt various binding modes such as monodentate, chelating one metal center, bridging two metal centers in a synsyn, syn-anti and anti-anti configuration, and bridging two metal centers in a tridentate form [10-11].
Some indole carboxylate compounds were detected internationally in patient samples, e.g., PB-22 (13, 14), 5F-PB-22 (15-17), and BB-22 (18).
In the [sup.31]P{[sup.1]H} NMR spectra these complexes displayed a pair of triplets resonance signals, corresponding to two transpositioned phosphorus atoms and two phosphorus atoms transpositioned to oxygen atoms from carboxylate groups of the quinaldate and kynurenate anions, respectively.
By increasing the temperature to 140[degrees]C, the characteristic bands for the carboxylate type ligands at 1617 [cm.sup.-1] and 1360 [cm.sup.-1] attributed to asymmetric and symmetric vibration of the CO[O.sup.-] groups increase, while characteristic bands for the nitrate decrease in intensity.

As discussed previously in related literature [13,14, 22], the passivation process is enhanced by adsorption of the carboxylates on the oxide-covered surface.
Spectra have also been reported (Micera and Erre, 1992; Boyd et al., 1981) for humic substances, found absorption bands for carboxylic acids and carboxylates.
[43] have reported a novel 2D coordination polymer 1 (Figure 5(a)) consisting of ferromagnetic Ni(II) chain with alternating double EO-azide bridges and (EO-azide)bis(carboxylate) triple bridges, and the material exhibits solvent sensitive metamagnetism; it can become 2 by dehydrating.
The deposits that formed at the inlet of the capillary tube of the R-134a/POE systems (least soluble) contained copper and iron carboxylates (carboxylic acids from brazing flux, POE hydrolysis, ester manufacturing oils, etc.) while mineral oil, silicone oil and other light oils deposited toward the exit of the tube (more soluble).
Troy Corporation announced that The Chidley & Peto Company, Arlington Heights, IL, is its new manufacturer's representative for specialty biocides and metal carboxylates in the Midwest region of the U.S.
Dispersants can vary from polycarboxylates (i.e., polyacids) that are very hydrophilic to copolymers of carboxylates and hydrophobic monomers that are considered hydrophobic dispersants.
