Abstrakt: The structure of the title compound is made up of a central sheet containing only metal and oxygen atoms with organic moieties outside and between sheets. The Cd(II) is on a crystallographic center of symmetry and is bound to six propionate oxygen atoms to yield a coordination geometry of an approximate octahedron. Each lithium has four oxygen nearest neighbors to form a distorted tetrahedral geometry. The lithium atoms are in pairs via oxygen bridges to form unsymmetrical Li2O2 parallelograms with a crystallographic center of symmetry in the middle. Crystal data: Li2Cd(C3H5O2)4,Mr=419, triclinic,P¯1,a=7.526(1),b=11.296(2),c=4.925(1) Å,a=94.85(2),ß=98.04(2), ?=78.97(2)°,V=406(1) Å3,Z=1,Dm=1.70(2),Dx=1.71 g cm-3, T ˜ 298K,R=0.028 for 2303 reflections.
