摘要：

The structure of the title compound has been investigated in the solid state and in solution by X-ray and NMR methods. The crystals are monoclinic: P2(1)/n, a = 9.010(2), b = 18.877(4), c = 9.434(2) angstrom, beta = 113.06(1)-degrees. The structure was solved by direct methods, and refined with 1764 unique reflections by full-matrix, least-squares to R = 0.0607 (R(w) = 0.0439). Although a two-fold symmetry of the molecule was suggested from NMR results, no approximate molecular symmetry elements were found in the crystalline state. Some intra- and intermolecular hydrogen bonds were observed.
