The title cadmium derivative of benzyloxyacetic acid, [Cd(C9H9O3)2]n, exists as a 2-carboxylate-bridged layer network. Two benzyloxyacetate units each chelate the metal through a carboxylate as well as through the ether O atoms; the metal is also coordinated by the double-bond carbonyl O atom of two adjacent benzyloxyacetate units in an octahedral geometry. The metal atom lies on a special position of 2 site symmetry. The phenyl group is disordered equally over two positions.
