Abstract The 1:1 and 1:2 adducts of 1,8-bis(dimethylaminomethyl)naphthalene (DMAMN) with picric acid were isolated. Both adducts crystallize in the space group Pī. The unit cell parameters for the 1:1 adduct are a =9.461(3), b =11.608(5), c =11.872(5)A, α=70.32(3), β=71.32(3) and γ=81.22(3)°, Z =2, and those for the 1:2 adduct are a =10.563(3), b =11.035(4), c =15.282(4)A, α=105.06(3), β=100.35(3)
摘要 分离了1,8-双(二甲氨基甲基)萘(DMAMN)与苦味酸的1:1和1:2加合物。两种加合物都在空间群 Pī 中结晶。1:1 加合物的晶胞参数为 a =9.461(3)、b =11.608(5)、c =11.872(5)A、α=70.32(3)、β=71.32(3) 和 γ=81.22 (3)°, Z =2, 1:2 加合物的那些是 a =10.563(3), b =11.035(4), c =15.282(4)A, α=105.06(3), β=100.35 (3) 且 γ=106.24(3)°,Z =2。1:1 加合物中的 NHN + 分子内氢键相对较长 (2.716(3)A),比质子化 1,8-双(二甲氨基)萘 (DMAN) (2.55–2.65A) 和 DMAMN 中的氢键长得多硝酸盐 (2.642(3)A)。在双质子化 DMAMN 中,形成了两个不等价的 N + H...O -
