通过将阴离子螯合配体（用于控制配位几何形状）与含有金属配位吡啶基部分和自互补氢键部分的双功能配体相结合，实现了六种不同的 M(II) 配合物（M = Cu、Co 和 Ni）定向组装成无限链。提出了六种晶体结构，在每种情况下，螯合 acac 配体占据四个赤道配位位点，为双功能配体在轴向位置配位留下了空间。超分子化学将配位配合物组织成所需的无限一维链，由 N-H 中心点 N 和 N-H 中心点 O 氢键的组合驱动。
The directed assembly of six different M(II) complexes (M = Cu, Co, and Ni) into infinite chains has been achieved by combining anionic chelating ligands (for controlling the coordination geometry) with bifunctional ligands containing a metal-coordinating pyridyl moiety and a self-complementary hydrogen-bonding moiety. Six crystal structures are presented, and in each case, the chelating acac ligand occupies the four equatorial coordination sites leaving room for the bifunctional ligand to coordinate in the axial positions. The supramolecular chemistry, which organizes the coordination complexes into the desired infinite 1-D chains, is driven by a combination of N-H center dot center dot center dot N and N-H center dot center dot center dot O hydrogen bonds.
