The crystal structure of zinc(II) fumarate tetrahydrate

Published/Copyright: August 25, 2010

Abstract

The crystal structure of zinc fumarate tetrahydrate, ZnC4H2O4 · 4 H2O, has been determined using three-dimensional single crystal X-ray data. The crystals are monoclinic, space group P21/c, Z = 4, with a = 7.58(2), b = 14.46(3), c = 7.66(2) Å, β = 101.2(1)°. The structure was solved by the heavy-atom method and refined by least-squares using 692 independent observed reflexions to a final R-value of 0.12. The zinc atom is surrounded by six oxygen atoms, at the corners of a distorted octahedron. Both the carboxyl groups in the molecule are twisted out of the plane containing the carbon atoms by angles of 49.4° and 15.8°.
