SYNTHESIS AND STRUCTURAL CHARACTERIZATION OF 2,6-BIS-(N-METHYLENEMORPHOLINO)-4-TER-BUTYLPHENOL

The crystal and molecular structure of the title compound, C20H32N2O3, has been determined from X-ray diffraction data using CuKalpha radiat ion (lambda = 1.5418 angstrom). The compound crystallizes in triclinic space group P1BAR with a = 8.828(1), b = 18.680(1), c = 6.272(2)angst rom, alpha = 93.42(1), beta = 90.24(2), gamma = 77.93(1)-degrees, V = 1009.4(2)angstrom3, and Z = 2. The structure was solved by direct meth ods and the full-matrix least-squares refinement leads the final R-fac tor to 0.065 for 3481 observed reflections with I greater-than-or-equa l-to 3sigma(1). The phenyl ring is planar and the morpholino rings ass ume perfect ''chair'' conformation. The molecules are held together by van der Waals forces.
