| 摘 要： | The title compound crystal belongs to the trilinic space group C_i~1—P(?) with unit cell parameters: a=11.208 (4), b=13.166 (4), c=13.239 (3),α=118.15 (2)°,β=94.78(2)°,γ=109.19 (2)°, and Z=1. The crystal structure was solved by direct method and difference Fourier techniques using the SHELXTL program, and was refined finally to R=R_W=0.0462 for 4702 reflections. Structural analysis shows that the four protons in the cluster of the decavanadate group are separated into two types. For one of them, the two protons are captured by two O7 in the cluster of the decavanadate and two nitrogen atoms of the hexamethylenetetramine, to form hydrogen bonds; moreover, we have verified that the N-aminomethylhexamethylenetetraminium which was produced during the reaction existed in the title compound crystal. We infer that the N-aminomethylhexamethylenetetraminium (CH_2)_6N_4CH_2NH_2]~+ could be produced by the heterogeneous catalysis reaction from the surface of the vanadium pentoxide V_2O_5].
