A pyrimidine-derived diphosphine P-monoxide and a Ag(I) coordination polymer thereof: synthesis, structure, and luminescence

(4-(Diphenylphosphino)pyrimidin-2-yl)diphenylphosphine oxide is unexpectedly formed in 24% yield in the reaction of 2,4-dichloropyrimidine with 2 equiv. of Ph2PLi in THF solution. It was demonstrated that title compound reacts with AgNO3 forming 1D polymer [Ag(L)NO3], wherein P,N,O-bringing coordination of the ligand is observed. At 300 K, both free ligand and the 1D polymer exhibit solid-state photoluminescence maximized at 480 and 538 nm with 3.2 ns and 2.95 µs afterglow times, respectively.
