The first Pb–Odouble bond; length as m-dash2 bonds on the righthand side bond, a novel 2D coordination polymer, [Pb(5-FUOAc)2]n, 5-FUOAc = 5-fluorouracil-1-acetate

A novel 2D polymeric PbII complex containing the first Pb–Odouble bond; length as m-dash2 bonds on the righthand side bond, [Pb(5-FUOAc)2]n (5-FUOAc = 5-fluorouracil-1-acetate), has been synthesized and characterized. The single-crystal X-ray data shows the coordination number in PbII ions is seven, PbO7, with “stereo-chemically active” electron lone pairs, and the coordination sphere is hemidirected.
