✦ Synopsis

a b s t r a c t 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 PO 3- 4 ions and -NH + 3 ions in the sample.
