Abstract: The title compound, [Cd(C₈H₅O₃)₂(C₁₂H₈N₂)][Cd₂(C₈H₅O₃)₄(C₁₂H₈N₂)₂], having the empirical formulation bis(4-formylbenzoato)(1,10-phenanthroline)cadmium(II), is a 1/1 cocrystal consisting of mononuclear and dinuclear molecules. In the monomeric molecule that lies on a special position of site symmetry 2, cadmium is chelated by the N-heterocycle as well as by both carboxylate units in a cis-octahedral geometry. The dimeric molecule lies on another special position of site symmetry 2 that relates two monomeric units; the octahedral Cd atom is chelated by one carboxylate group and the N-heterocycle; the other carboxylate group functions as a carboxylate bridge between the two metal atoms.
