Effects of Ti substitution at Ir-site on structural and electrical properties are studies in Sr{sub 2}IrO{sub 4}. Structural investigation has been done using x-ray powder diffraction and allied Rietveld analysis for all the samples. While there is no structural phase transition but the lattice parameters evolve with Ti doping. Resistivity measurements show an insulating behavior for all the samples. Data show resistivity increases drastically with Ti doping. The increase in resistivity is understood to arise due to dilution of Ir-O-Ir network as well as tuning of electronic correlation effect.
