Abstract : Structural Studies of iron molybdenum phosphate glasses were carried out using infrared (IR) radiation, density, VicKer hardness measurements and conductivity. Fe2O3 concentration ranging from 2.5 to 15 mol% was introduced at the expense of MoO3 content. The measurements have shown that molybdenum participates predominantly in the six fold coordinated (MoO6) and four fold coordinated (MoO4), iron participates also in tetrahedral (FeO4) and octahedral (FeO6) concentrations. Small amount of (PO2) and/or (PO3), (PO4) groups are also present in the network former position. The increase in the FeO3 content lead to the formation of covalent bond between the non bridging oxygen (NBO) ions and iron ions to form (P-O-Fe) units as well as to increase the (MoO4) groups
