X-ray powder diffraction data for (1R, 5S, 7R)-7-[(S)-4-tert-Butyl-4,5-dihydrooxazole-2-yl] -1,5,7-trimethyl-3-azabicyclo-[3.3.1]-nonane-2,4-dione, a new chiral Kemp’s acid diamide

X-ray powder diffraction data, unit-cell parameters and space group for a new chiral Kemp’s acid diamide, C18H28N2O3, are reported [a = 12.456(2) Å, b = 12.471(2) Å, c = 12.088(2) Å, β = 99.003(2)°, unit-cell volume V = 1854,48 Å3, Z = 4, space group P21]. All measured lines were indexed and are consistent with the P21 space group. No detectable impurity was observed.
