Co(II) ion doped chlorocadmiumphosphate crystals: A novel organically templated hybrid open-framework

Co(II) doped chlorocadmiumphosphate crystals are synthesized in acidic conditions at room temperature. Powder X-ray diffraction data of this compound indicates that it crystallizes in monoclinic space group with lattice parameters a = 1.7720 , b = 1.1509 , c = 0.9912 nm and β = 100.9 ° . The low temperature EPR spectrum reveals the presence of two resonances at g = 4.36 and g = 2.0 , which indicates distorted octahedral site for Co(II) ions. Optical absorption studies of the complex further confirm the near octahedral symmetry for the dopant ion. FT-IR studies confirm the presence of PO43− ions and −NH3+ ions in the sample.
