摘要：

Single crystal EPR, optical, FT-IR, and powder XRD studies of VO2+ ion-doped diaquacadmium(diaquabismalonato)cadmate were carried out at ambient temperature to ascertain the structural properties. In EPR, the angular variation of VO2+ ion hyperfine lines indicated a single site, with spin Hamiltonian parameters g and A values g (xx) = 1.979, g (yy) = 1.963, g (zz) = 1.939, A (xx) = 0.0074 cm(-1), A (yy) = 0.0065 cm(-1), and A (zz) = 0.0166 cm(-1). The calculated results of the VO2+ ion-doped diaquacadmium(diaquabismalonato)cadmate indicate VO2+ substitutes the Cd2+ ion in the host lattice, and it has rhombic symmetry. The EPR and optical absorption data were corroborated to obtain various bonding parameters, from which the nature of bonding in the complex was discussed. FT-IR and powder XRD studies were used to observe the effect of dopant on structural parameters of the host lattice.
