In the title complex, [Ca(C10H6NO2)(2)(H2O)(2)](n), the Ca-II ion is eight-coordinated by six carboxylate O atoms from four separate quinoline-3-carboxylate ligands, two of which are bidentate chelate and two bridging, and two water molecules in a distorted square-antiprismatic geometry. The bridging groups form a polymeric chain substructure extending along the c axis, the chains being connected by coordinated-water O-H center dot center dot center dot N and O-H center dot center dot center dot O-carboxylate hydrogen bonds into a three-dimensional framework structure.
