An unprecedented 3D entangled framework, {[Co(bib)(hoip)]·6H2O}n (1), has been synthesized by using rigid and flexible mixed-ligands, which represents to the best of our knowledge, the first example of one-fold inclined 1D → 3D polycatenated networks built by the vertical interlocking of novel interweaving triple-stranded helices sharing the same CoII nodes.
