The title compound, [Cd(C8H6BrNO4S)(C12H8N2)(CH4O)], incorporating a Schiff base formed by aminomethanesulfonic acid and 5-bromosalicylaldehyde, was synthesized in a water methanol solution. In the structure, the Cd-II atom is six-coordinated by one O atom from a methanol molecule, two N atoms from a 1,10-phenanthroline ligand, and one N and two O atoms from the Schiff base in a distorted octahedral coordination geometry. A one-dimensional chain structure is forme...
