Abstract

Abstract: Powder XRD, EPR, optical, NLO activity and Biological activities of Fe(III)doped Mn(II)L-Histidine Hydrochloride Monohydrate (LHICl) was carried out at room temperature to ascertain the structural properties. In EPR, the angular variation of Fe(III) hyperfine lines indicated a single site, with spin Hamiltonian parameters (g) values g = 2.0292, The calculated results of the Fe(III)doped Mn(II)L-substitutes the Fe(III) ion in the host lattice, and it has orthorhombic symmetry. The EPR evaluated lattice cell parameters, a = 1.5320, b = 0.8450 and c = 0.6834 nm and V = 884.69 Å 3 and optical absorption data Dq = 700, B= 610, C= 2360 [α] = 90 cm -1 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.
