Cadmium(II) diacetate trihydrate (0.14 g, 0.5 mmol) was added to an H2O/EtOH solution (1:1 v/v) of 4-formylbenzoic acid (0.15 g, 1 mmol) and 1,10-phenanthroline (0.099 g 0.5 mmol). Sodium hydroxide (0.1 M) was added dropwise until the solution registered a pH of 5. Pale yellow single crystals separated from the filtered solution after several days. Elemental analysis: calcd. for C28H20N2O7Cd: C 55.23, H 3.31, N 4.60. Found: C 55.25, H 3.24, N 4.62.
Carbon-bound H atoms were placed in calculated positions, with C—H = 0.93 and Uiso(H) = 1.2Ueq (C), and were included in the refinement in the riding model approximation. The H atoms of water molecules were located in difference Fourier maps and refined with the O—H and H···H distance restraints to 0.85 (1) and 1.39 (1) Å, and with Uiso(H) = 1.5Ueq(O).
An earlier report (Deng et al., 2006a) detailed the synthesis and crystal structure of a zinc complex with 1,10-phenanthroline and 4-formylbenzoato ligands. Replacing zinc by cadmium in a similar reaction leads to the formation of the title complex, (I) (Fig. 1). The Cd(II) atom displays a trigonal prismatic geometry, which is different from the zinc complex and another cadmium phenanthroline adduct, (II) (Deng et al., 2006b). The two basal planes of the trigonal prism are built up by O1, O1, N2 and O2, O4, N1, respectively. The Cd—O and Cd—N bond lengths are similar to complex (II). Interestingly, one of the 4-formylbenzoato ligands shows a coordination to cadmium only via one of the oxygen atoms whereas the other oxygen atom is engaged in a strong intramolecular hydrogen bond toward the aqua ligand. Adjacent complex molecules are linked into a two-dimensional layer structure via hydrogen-bonding interactions (Table 1, Fig. 2).
For the zinc phenanthroline adduct, see Deng, Gao, Huo et al. (2006), and for the cadmium phenanthroline complex, see Deng, Gao & Ng (2006).

An earlier report (Deng et al., 2006a) detailed the synthesis and crystal structure of a zinc complex with 1,10-phenanthroline and 4-formylbenzoato ligands. Replacing zinc by cadmium in a similar reaction leads to the formation of the title complex, (I) (Fig. 1). The Cd(II) atom displays a trigonal prismatic geometry, which is different from the zinc complex and another cadmium phenanthroline adduct, (II) (Deng et al., 2006b). The two basal planes of the trigonal prism are built up by O1, O1, N2 and O2, O4, N1, respectively. The Cd—O and Cd—N bond lengths are similar to complex (II). Interestingly, one of the 4-formylbenzoato ligands shows a coordination to cadmium only via one of the oxygen atoms whereas the other oxygen atom is engaged in a strong intramolecular hydrogen bond toward the aqua ligand. Adjacent complex molecules are linked into a two-dimensional layer structure via hydrogen-bonding interactions (Table 1, Fig. 2).
