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.
6
Here the organic ligand acts as tetradendate linker via two of the carboxylategroups.
7
Surprisingly, the ion selectivity of the smaller diameter pore containing three carboxylategroups can be tuned by changing the magnitude of the applied voltage bias.
8
The copper (II) ions are in a distorted tetrahedral environment sequentially bridged by carboxylategroups in the syn-anti conformation giving rise to a helix-like chain.
