Di-aqua-bis-(cinnamato-κ(2) O,O')cadmium.

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