X-ray powder diffraction data for levetiracetam

Experimental X-ray powder diffraction data, unit-cell parameters, and space group for levetiracetam, C 8 H 14 N 2 O 2 , are reported [ a = 9.197(5) Å, b = 8.006(0) Å, c = 6.289(3) Å, β = 108.457(3)°, unit-cell volume V = 439.261 Å 3 , Z = 2, and space group P 2 1 ]. All measured lines were indexed and are consistent with the P 2 1 space group. No detectable impurity was observed.
