The vacuum sintered alloy with nominal composition of FeTe was analyzed using powder X-ray diffraction and refined with Rietveld method. It is shown that FeTe alloy crystallizes a tetragonal structure with space group of P/4nmm and its lattice constant is a = 3.8214(3)Å, c = 6.2875(3) Å, Z = 2. Fe at 2a and 2c positions and Te at 2c positions. FeTe films prepared by pulsed laser deposition showed superconducting transition with starting transition temperature Tc,onset of 13.2 K and Tc,0 of 9.8 K.
