These observations were tentatively related to the strength of the metal-carboxylate bond.
2
On the other hand, the carboxylate form of CPT-11 exhibited much less variability.
3
Each anion had a carboxylate group and at least one other polar moiety.
4
Remarkably, both of these challenges were overcome by incorporation of a single carboxylate moiety.
5
Here the organic ligand acts as tetradendate linker via two of the carboxylate groups.
1
Each anion had a carboxylategroup and at least one other polar moiety.
2
The carboxylategroup of the benzoate moiety must be in ortho position to the amino group.
3
The free carboxylategroup(s) in the MOFs inspire us to elaborate their metal capturing properties.
4
The carboxylategroup of propionate bound in the active site makes numerous interactions with active-site residues, defining the substrate binding site of the enzyme.
5
These differences may be explained by the large hydration potential of Arg and the formation of a salt bridge with a carboxylategroup of oxaloacetate.
