Abstract
The ^109^Ag NMR spectrum of [Ag(Ph~2~PCHCHPPh~2~)~2~]NO~3~, a complex with antimicrobial and antitumour activity, was obtained using a retro‐INEPT two‐dimensional ^31^P–{^109^Ag} pulse sequence. This allowed the measurement of the ^31^P and ^109^Ag chemical shifts and the ^1^J(^109^Ag,^31^P) coupling constant in a single 2 h experiment and offered a considerable signal‐to‐noise gain compared with ^109^Ag–{^31^P} INEPT measurements.
