Weak paramagnetism in compounds of the type Cp2Yb(bipy)
Measuring the magnetic moments of solids that are air and moisture sensitive is difficult, particularly when the net magnetic moments are small, as is the case for the organometallic compounds described here. The use of quartz tubes to contain the compounds has been developed and applied to substituted ytterbocene bipyridine complexes, some of which were previously reported as diamagnetic. The SQUID measurements quantify the extent of paramagnetism and they correlate with the qualitative variable temperature 1H NMR spectra.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
