✦ Synopsis

Nitrogen-15 NMR spectra of the complexes and

] , each containing 15N at natural abundance, were obtained by indirect detection (HMQC) using phosphorus as the observed nucleus. Data collection times varied from 4 h to 4 d depending upon the accuracy of the estimated value of 2J(31P,15N) used to optimize the pulse sequence. 1997
