The title compound is C3H3O4Cs, CsHM, monoclinic,P21/c,a=8.393 (3),b=7.960(2),c=9.023(2) Å,ß=92.11(2)°. The structure was solved by the heavy-atom method and refined by least-squares techniques to anR factor of 0.023 for 760 observed reflections. The CsHM has no internal symmetry and one carboxy group, but not the other, is twisted almost at right angles (96°) to the plane of the three central carbon atoms. The hydrogen malonate anions are linked together by two short and symmetrical O-H?O hydrogen bonds [2.468(4) and 2.482(4) Å]. The structure consists of hydrogen malonate chains cross-linked by the Cs+ ion. The IR spectrum of CsHM has been analyzed. |
