AbstractThe crystal structure of the title compound has been determined. MW = 248.315, the crystals are orthorhombic, space group Pnma with a = 15.695(9), b = 7.592(3), c = 8.508(3) Å, V = 1013.8(8) Å3, Z = 4, Dc = 1.627(3) Mg · m−3, μ = 8.550 mm−1, λCuKα, F(000) = 512. It was refined to R = 0.051, Rw = 0.054, for 846 unique observed reflections with I > 2 σ(I). The ion succinate lies on a mirror plane as well as the water molecules. The K+ ion is linked to six oxygen atoms in a distorted octahedral coordination with distances ranging from 2.716(3) to 3.070(4) Å. The molecules are linked by hydrogen bonds and coupled through potassiums ions forming layers at ¼ and ¾ of b.
