Abstract Hydrogen bond is very important to regulate the structure and symmetry of crystal. To change the quantum motifs of small molecular which will lead to different structure and symmetry of crystal by adding small organic amine is still very interesting research. Different (NH2CH2CH2NH2)⋅x(H+) (x = 0–2) species was found to change the quantum motifs of bulk crystal consisted of [MoO2(C6H4O2)2]2− anion. And the different quantum motifs of the two crystals build different crystallographic system, means allomorphs. Two morphology nanomaterials (thin and long nanowire and spiral nanotube) were obtained from the couple of allomorphs by top-down method. XRD indicated that hydrogen bond not only maintained the stability of the quantum motifs but also provided a possibility for quantum motifs reassembly to construct unique nanomaterials.

乙二胺对钼基复合晶体量子基序的影响

摘要 氢键对调节晶体的结构和对称性非常重要。通过加入小分子有机胺来改变小分子的量子基序，从而导致不同的晶体结构和对称性，仍然是一项非常有趣的研究。发现不同的 (NH2CH2CH2NH2)⋅x(H+) (x = 0–2) 物种会改变由 [MoO2(C6H4O2)2]2− 阴离子组成的块状晶体的量子基序。并且两种晶体的不同量子基序构成了不同的晶体学体系，即同质异形体。通过自上而下的方法从这对异形体中获得了两种形态纳米材料（细长纳米线和螺旋纳米管）。XRD 表明氢键不仅保持了量子基序的稳定性，而且为量子基序重新组装以构建独特的纳米材料提供了可能性。
