Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The crystal and molecular structure of chiral crown ether, (S)-2-[(4-methoxyphenoxy)methyl]-15-crown-5⋯NaClO, has been determined by single-crystal X-ray diffraction. The complex crystallizes in the orthorombic space group Pbca with Z = 8. Lattice parameters are a = 11.451(2), b = 12.842(3), c = 31.330(7) Å. The structure was refined to R factor of 0.0547. The Na ion is heptacoordinated. The Na-O distances range from 2.363(4) to 2.433(4) Å and average 2.404(5) Å. Perchlorate anion is bounded to sodium ion asymmetrically; the Na-O8 and Na-O9 distances are 2.444(5) Å and 2.607(5) Å. The C-O and C-C distances of the 15-membered ring average 1.419(9) and 1.478(12) Å while the O-C-C and C-O-C angles average 108.2(6°) and 115.4(6°). © 2008 Springer Science+Business Media, LLC.
