The invention discloses pentamodiamine suberate and its crystal structure, and a preparation method thereof. The pentamethylenediamine suberate is a salt which exhibits a solid state at a normal temperature in which a pentanediamine divalent cation and a suberic acid dianion are combined in a molar ratio of 1:1. Its crystal structure is C 13 H 28 N 2 O 4 , monoclinic system, C2/c space group, α=90.00°, β=117.673(4)°, γ=90.00°, unit cell volume The minimum number of asymmetric units in the unit cell is Z=4, and no crystal water is contained. The preparation method comprises crystallizing pentamethylenediamine suberate from a solution containing dissolved pentamethylenediamine and suberic acid, separating crystals from the solution, and drying the separated crystals. |
