• Two new layered cadmium iodates Cd(IO3)X (X=Cl, OH) are reported.
• Cd(IO3)Cl features a unique double layered structure.
• Cd(IO3)(OH) displays an ordinary layered structure.
• The spectroscopic and thermal properties have been studied in detail.
Systematic explorations of new compounds in the cadmium iodate system by hydrothermal reactions led to two layered iodates, namely, Cd(IO3)X (X=Cl, OH). Cd(IO3)Cl crystallizes in the orthorhombic space group Cmca (No. 64) whereas Cd(IO3)(OH) crystallizes in the orthorhombic space group Pnma (No. 62). Cd(IO3)Cl displays a unique double layered structure composed of [Cd−O3Cl]n∞1 chains. Cadmium octahedrons form a 1D chain along the a-axis through edge sharing, and such chains are further interconnected via IO3 groups to form a special double layer on (020) plane. Cd(IO3)(OH) also exhibits a layered structure that is composed of cadmium cations, IO3 groups and hydroxyl ions. Within a layer, chains of CdO6 edge-shared octahedra are observed along the b-axis. And these chains are connected by IO3 groups into a layer parallel to the bc plane. Spectroscopic characterizations, elemental analysis, and thermogravimetric analysis for the reported two compounds are also presented.
