篇名 N，N'-双（4-羟基－3-甲氧基苯甲基）草酰胺的合成及晶体结构研究

DFT Study on Heterobinuclear Cu-Co Complex of N,N'-bis (3-carboxyl Salicyl Aminal Ethylene) Oxalamide

篇名 N，N'-双（3-羧基水杨醛叉缩胺乙基）草酰胺Cu-Co异双核配合物的密度泛函研究

The new oxalamide bridging ligands N, N'-bis (4-hydroxy-3-methoxy-benzyl) oxalamide (H4LB) was designed and synthesized.

设计合成一种新型对称的草酰胺桥联配体：N，N'-二（4-羟基－3-甲氧基苯甲基）草酰胺配体(H4LB)。

The structure analysis indicates that the reverse symmetry ligand H4LB molecules are linked into a 2D supermolecular network by two types of hydrogen bonds. One type occurs between the oxalamide oxygen group and the phenol hydroxyl qroup of the nearest molecule with d=2.906(2) and ∠O-H…O=151.8°. The other type is between the oxalamide nitrogen group and the oxalamide oxygen group of anther molecule with d=2.849(2),∠N-H…O=158.7°.

晶体结构研究表明配体H4L为顺式桥联分子，晶体中存在两种氢键，一种是草酰胺基团的O原子与苯环上的酚羟基形成O-H…O氢键[d=2.906(2)，∠O-H…O=151.8°]；另一种是草酰胺基团的氨基与相邻草酰胺基上的O原子形成N-H…O氢键[d=2.849(2)，∠N-H…O=158.7°]，通过上述两种氢键将化合物H4LB连接成二维网络结构。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
