The crystal structure of manganese(II) succinate tetrahydrate

Abstract

Abstract The crystal structure of manganese(II) succinate tetrahydrate, Mn(C4H4O4) · 4H2O, has been determined from single crystal X-ray diffraction data. The crystals are triclinic, space group P[unk] with a = 5.50(1), b = 9.05(2), c = 5.26(1) Å, α = 96.1(5), β = 98.9(5), γ = 120.5(5)°, Z = 1. The structure was solved by the heavy-atom method and refined to a final R-value of 0.11 for all the 501 observed reflexions. The Mn2+ ion is coordinated with six oxygen atoms with distances ranging from 2.18 to 2.24 Å. Both the carboxyl groups in the succinate anion are twisted out of the plane of the four carbon atoms by 7.7°.
