资源简介：
A bismuth-based metal–organic
framework (MOF), [Bi(BTC)(H2O)]·2H2O·MeOH
denoted CAU-17, was synthesized
and found to have an exceptionally complicated structure with helical
Bi–O rods cross-linked by 1,3,5-benzenetricarboxylate (BTC3–) ligands. Five crystallographically independent 1D
channels including two hexagonal channels, two rectangular channels,
and one triangular channel have accessible diameters of 9.6, 9.6,
3.6, 3.6, and 3.4 Å, respectively. The structure is further complicated
by twinning. Rod-incorporated MOF structures typically have underlying
nets with only one unique node and three or four unique edges. In
contrast, topological analysis of CAU-17 revealed unprecedented complexity
for a MOF structure with 54 unique nodes and 135 edges. The complexity
originates from the rod packing and the rods themselves, which are
related to aperiodic helices.
