“…Procedure used for Cu(II) and VO(II) ion in diaqua(2,2'-bipyridine)malonatozinc(II) had been adopted here also. 24 The Cartesian coordinates for the zinc atoms, surrounding water, phenanthroline molecules and malonate anions in the unit cell can be calculated by making use of fractional coordinates and unit cell dimensions. 28 The exact interstitial arrangement of VO(II) in DMPZ is calculated out of all assumptions made and shown in Figure 7.…”

Single crystal EPR and optical studies of a mixed ligand zinc(II) complex doped with VO(II) ion is carried out to establish the structural properties. The angular variation of vanadyl hyperfine lines indicates a single site, with spin Hamiltonian parameters as: g xx = 1.985, g yy = 1.979, g zz = 1.943; A xx = 8.71, A yy = 6.41 and A zz = 17.80 mT. By comparing the direction cosines of principal g and A values with the direction cosines of metalligand bonds, it has been confirmed that the vanadyl ion has entered the lattice interstitially. The exact interstitial position of VO(II) in host lattice has been calculated using the fractional coordinates of atoms in the host lattice out of many assumptions. The EPR and optical data have been confirmed to obtain various bonding parameters, from which the nature of the bonding in the complex is discussed. FT-IR confirms the formation of structure of host lattice.

“…[14][15][16] Past few years our research group has focus on single crystal EPR studies of transition metal ions doped zinc malonate complexes. [17][18][19][20][21] In this way, we have chosen an alkaline metal based zinc malonate polymer as good dopant to incorporate by vanadyl ion. The present exploration of the EPR and optical studies of vanadyl doped in Diaquacesiumaquabismalonatozincate polymer (here after abbreviated as DCBZ) has been undertaken to find the spin Hamiltonian parameters, the location of paramagnetic impurity and other structural and bonding parameters.…”

Single crystal EPR and optical studies of vanadyl doped diaquacesiumaquabismalonatozincate (DCBZ) have been reported at room temperature using X-band frequencies. Single crystal rotations carried out in the three mutually orthogonal planes, each plane furnish eight hyperfine lines, it specifies that only one site vanadyl present in the lattice. The spin Hamiltonian parameters obtained are: g xx = 1.991, g yy = 1.991, g zz = 1.937; A xx = 7.59, A yy = 7.59 and A zz = 19.80 mT. By evaluating the direction cosines of principal g and A values with the X-ray data of DCBZ, it has been confirmed that the impurity has entered the lattice interstitially. The optical adsorption shows four bands, it help to calculate crystal field parameters Dq, Dt and Ds. Molecular orbital parameter such as Admixture coefficients, Fermi contact (k) and dipolar interaction (P) have also been calculated from powder EPR spectrum of VO(II) doped DCBZ. Zn-O, COO-, -OH bonds have been established by FTIR. Powder XRD techniques have been used to characterize the structure of the complex in the presence dopant.
