The title complex, {[Cd 3 (C 4 H 4 O 4 ) 3 (C 12 H 8 N 2 ) 3 ]Á4H 2 O} n , has been isolated from the hydrothermal reaction of cadmium acetate with 1,10-phenanthroline (phen) and succinic acid. The structure features two-dimensional networks formed by succinate ligands bridging Cd atoms in two different coordination modes. A twofold rotation axis passes through one Cd atom. In one coordination mode, the Cd atoms are in a distorted octahedral CdO 4 N 2 arrangement and the coordination atoms come from one phen ligand and two succinate ligands. In the other coordination mode, the Cd atoms are in the decahedral CdO 5 N 2 geometries and the coordination atoms come from one phen ligand and three succinate ligands.
