Abstract

In the title complex, [Ca(C 10H 6NO 4) 2(H 2O) 2] n , the Ca II atom lies on a twofold rotation axis and adopts a dodeca-hedral geometry. The Ca II atom is octa-coordinated by two O atoms from two water molecules and six O atoms from four acetate ligands. Each acetate acts as a tridentate ligand bridging two Ca II atoms, resulting in a chain running along the c axis. O - H⋯O and C - H⋯O hydrogen bonds connect the chains into a two-dimensional network parallel to [011]. π-π interactions between adjacent isoindoline-1,3-dione rings [centroid-centroid distance = 3.4096 (11) Å] further consolidate the structure. One of the carboxylate O atoms is disordered over two sites in a 0.879 (12):0.121 (12) ratio.
