Sentence examples for chelate rings from inspiring English sources

Further analysis of the CSD has shown that chelate rings, both isolated and fused stack with other chelate rings.

DQPEA and DQPMA differ only in that DQPEA forms six-membered chelate rings that involve the pyridyl group, whereas DQPMA forms analogous five-membered chelate rings.

The stretching vibrations of Nd O bonds and chelate rings are observed in the 400 650 cm−1 region.

They also reported how the distortion in the chelate rings leads to larger value of quadrupolar coupling constant in one of the complexes.

An example of chain length's importance is its effect on trace metal chelation by polysulfides; only Sn2− ions having n ≥ 4 are able to form chelate rings.

The five-membered chelate rings of PDA lead to strong selectivity for larger metal ions, including Cd II), La III), and Gd III).

This supports the chelate ring-size rule (R.D. Hancock, A.E. Martell, Chem. Rev. 89 (1989 18755) that states that increase of chelate ring size stabilizes the complexes of smaller metal ions relative to those of larger metal ions.

The smaller aluminum chelate ring size and the resulting bigger ring tension may contribute to the high activity.

Ligands coordinated with metal ions to get a five-membered chelate ring and formed polymeric complexes with metal ion.

In Fe complex, Fe3+ is coordinated through N2 and S sites of TSC and formed the chelate ring {C7N3N2FeS}.

The DFT calculations show that increase of chelate ring size usually leads to a decrease in stability of the Ni II) complex, but correctly predict that the 2,3,2-tet complex will be more stable than the trien complex, which is an unusual example where replacing a 5-membered chelate ring with a 6-membered chelate ring leads to higher complex stability.
