The compound, 2,2-[(pentane-1,5-diyldioxy-bis)-bis-(nitrilomethylidyne)]dinaphthalene has been synthesized by 1,5-bis-(aminooxy)pentane and 2-naphthaldehyde in ethanol solution and characterized structurally by X-ray crystallography. The molecule of the title compound, C27H26N2O2, assumes a dipolymer structure through a weak C-H···C hydrogen-bonding interactions. And the single crystal structure of the compound revealed all-conformation of the (-CH=N-O-(CH2)5-O-N=CH-) linkage, which resulted in the structure with two nitrilomethylidyne units apart from each other. The compound is sufficiently stable to resist scrambling of the C=N bonds. This may be ascribed to lower reactivity of the C=N-O bonds toward nucleophiles.

C27H26N2O2 的分子通过微弱的 C-H-C 氢键作用形成二聚体结构。该化合物的单晶结构显示了(-CH=N-O-(
CH2)5-O-N=CH-)连接的全构象,从而形成了两个相距较远的氮甲基单元的结构。该化合物具有足够的稳定性,可以抵御 C=N 键的破坏。这可能是因为 C=N-O 键对亲核物的反应性较低。
