Di­aqua­bis­(cinnamato-κ2O,O′)cadmium

The title complex, [Cd(C9H7O2)2(H2O)2], was obtained as an unintended product of the reaction of cadmium nitrate with hexa­methyl­ene­tetra­mine and cinnamic acid. The CdII ion lies on a twofold rotation axis and is coordinated in a slightly distorted trigonal–prismatic environment. In the crystal, the V-shaped mol­ecules are arranged in an inter­locking fashion along [010] and O—H⋯O hydrogen bonds link the mol­ecules, forming a two-dimensional network parallel to (001).
