双-二齿桥连配体L-1与Co（ClO 4）（2）或Zn（BF 4）（2）反应得到具有相同金属：配体比的配合物[M-8（L-1）（12）]X-16和[M-6（L-1）]X-12的混合物：前者是在每个顶点处具有金属离子和跨越每个边缘的桥连配体的分子立方体，而后者具有类似于含有交联的双螺旋金属配体亚单位的“打开的书”的金属框架。
Reaction of the bis-bidentate bridging ligand L-1 with Co(ClO4)(2) or Zn(BF4)(2) affords a mixture of complexes [M-8(L-1)(12)]X-16 and [M-6(L-1)]X-12 having the same metal: ligand ratio: the former is a molecular cube with a metal ion at each vertex and a bridging ligand spanning each edge, whereas the latter has a metal framework like that of an 'open book' containing cross-linked double helical metal-ligand subunits.
