Abstract

Reaction of 4,4′-bipyridine N,N′-dioxide (bpno) and lead(II) nitrate with or without dicyanamido ions (dca) in aqueous solution yielded polymeric complexes {Pb₂(bpno)₄(dca)₂-(NO ₃)₂Pb₂(bpno)₄(NO₃) ₄·5H₂O}_n (1) and {Pb(bpno)(NO ₃)₂· H₂O}_n (2), respectively. The single-crystal X-ray analyses show that the structures of both complexes consist of dinuclear Pb^II units which are bridged through bpno ligands in novel modes to extend their topologies. Compound 1 exhibits a bilayered rhombus grid, while 2 displays a monolayered rhombus grid. The different excitations of solid samples of 1 and 2, at room temperature, produced intense emission bands which are almost the same in appearance with peak maxima at 616 nm and 617 nm, respectively. Both low-energy emissions were determined to be phosphorescence by their long decay lifetime at room temperature.
