In the title complex, [CdCl(2)(C(4)H(8)O(2))](n), two different Cd(II) ions are present, one in a general position and one with site symmetry 2. The Cd(II) ions are coordinated by two O atoms from two 1,4-dioxane ligands and four chloride anions in a slightly distorted octa-hedral geometry and is connected to neighboring Cd(II) ions by two bridging chloride anions, generating infinite linear chains along the a axis. These chains are further inter-connected by bridging 1,4-dioxane ligands, affording a three-dimensional network.
