Abstract
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,M r =419, triclinic,P¯1,a=7.526(1),b=11.296(2),c=4.925(1) Å,α=94.85(2),β=98.04(2), γ=78.97(2)°,V=406(1) Å3,Z=1,D m =1.70(2),D x =1.71 g cm−3, T ≈ 298K,R=0.028 for 2303 reflections.
