Abstract:
The crystal structure of catena-poly[[(6-carboxypyridine-2-carboxylato-kappa3O,N,O')lithium(I)]-mu-aqua-kappa2O:O], [Li(C(7)H(4)NO(4))(H(2)O)](n), contains the Li(+) ion coordinated to two O atoms and the N atom of the 6-carboxypyridine-2-carboxylate ligand, and to two water O atoms, forming a pentavalent coordination geometry. The molecule resides on a mirror plane which contains the Li and N atoms, the para-CH unit, and the O atom of the coordinated water molecule. The O atom of the water molecule is coordinated to two Li atoms, forming an infinite polymeric chain.
