摘要：
The crystal structure of the title compound has been determined. The compound crystallizes in the monoclinic space group P2(1)/c with a = 5.9885(2) angstrom, b = 14.7345(4) angstrom, c = 12.3719(4) angstrom, beta= 96.655(5)degrees, V = 1084.31(8) angstrom(3), z = 4. An intramolecular N-H center dot center dot center dot N hydrogen bond forms a pseudo-six-membered ring with graph set S-1(1)(6). The crystal structure is stabilized by intermolecular interactions of the type N-H center dot center dot center dot N and C-H center dot center dot center dot N. The packing motifs in accordance with Etter's analysis are R-2(2)(8) corresponding to N-H center dot center dot center dot N dimer and that generated by the chain is C(7).
