摘要：

C8H10N4O3, M = 210.18, triclinic space group P1BAR, a = 10.193(1), b = 12.401(1), c = 8.061(1) angstrom, alpha = 97.80(1), beta = 98.28(1), gamma = 107.89(1)degrees, V = 941.9(2) angstrom3, Z = 4, D(x) = 1.581 g cm-3, lambda(MoK(alpha) = 0.71073 angstrom, mu = 1.2 cm-1, F(000) = 384. The crystal structure was determined by direct methods and refined by least-squares procedure to a discrepancy factor R = 0.035. The two molecules of the asymmetric unit are tautomeric forms characterized by an ketamine-hydroxyimine tautomerism.
