What is Hydrothermal synthesis and structure of a 2D supramolecular framework with right- and left-helices based on mixed ligands about?

## Abstract An exploration of the cobalt‐OH‐BDC‐bpp system under hydrothermal conditions, has led to the isolation of a novel framework [Co(OH‐BDC)(bpp)~0.5~(H~2~O)]~n~ (OH‐BDC = 5‐hydroxyisophthalic acid, bpp = 1,3‐bi(4‐pyridyl)propane). Single‐crystal X‐ray analysis reveals that it crystallizes in the monoclinic space group P2~1~/n. __a__ = 10.235(8) Å, __b__ =17.882(14) Å, __c__ = 14.291(11) Å, β = 92.107(9)°.The cobalt ions are linked into an extended helical chain __via__ OH‐BDC and mono‐coordinated bpp ligands through hydrogen‐bonding interactions. Further these helical chains are united together through the bridging bpp to form a 2D layer and the adjacent chains possess the opposite chirality. (© 2008 WILEY‐VCH Verlag GmbH & Co.
