title: catena-Poly[[diaqua-lithium]-μ-[rac-cis-(2-carb-oxy-cyclo-hexane-1-carboxyl-ato-κO:O]].
abstract: In the structure of the title compound, [Li(C(8)H(11)O(4))(H(2)O)(2)](n), the distorted tetra-hadral LiO(4) coordination sphere comprises two water mol-ecules and two carboxyl O-atom donors from separate bridging cis-2-carb-oxy-cyclo-hexane-1-carboxyl-ate monoanions [Li-O = 1.887 (4)-1.946 (3) Å], giving chain substructures which extend along [010]. Water-water and water-carboxyl O-H⋯O hydrogen bonds stabilize these chain structures and provide inter-chain links, resulting in a two-dimensional layered structure extending parallel to (100).
