Two Exceptional Patterns of Helical Secondary Building Units Found in Metal–Organic Framework Structures

Abstract

Supplementary InformationStandard simplification of two three-way rod MOFs leads to complicated underlying net that called 4,4,4,4T73 (Fig.S1).

Coordination Properties of Hydroxyisophthalic Acids: Topological Correlations, Synthesis, Structural Analysis, and Properties of New Complexes

“…These clusters can form island architectures (dimer, trimer, tetramer) of the infinite rod and layer, and their formation correlates with the network periodicity. [31] Thus all 3D frameworks, 17 of 20 2D layers, and 3 of 4 0D molecular complexes contain clusters, while clusters are rare for 1D chains (2 of 14). The presence of rods is the most prominent in 3D frameworks (15 of 25), and they are usually constructed with rare-earth metals.…”

“…Further, each of two symmetry equivalent carboxylic groups of 5-hip contains two symmetry inequivalent O atoms. Therefore depending on the binding to one or another inequivalent O atom two or three different geometries of coordination exist for the symbols B 2 (3), T 4 (2), K 31 (2), K 22 (3), and P 32 (2). We found H 2 -5-hip being able to give from 1 to 5 oxygen atoms for binding from 1 to 7 metal atoms, while H 2 -4hip and H 2 -4,6-dhip use all 5 and 6 donor atoms in coordination with 5 and 8 metal atoms, respectively.…”

Design and synthesis of copper(ii) malonates with N,N′-containing linkers

“…Some examples of reticular chemistry approaches to the design of coordination polymers with novel topologies by using polytopic ligands with a controlled coordination mode and metal ions with a controlled coordination figure are described in ref. 10–17. Also, some examples of expert systems to predict 2D and 3D coordination polymers for copper( i , ii ) heterocyclic N-oxides, 18 zinc( ii ) malonates, 8,9 metal 4,5,6-trihydroxyisophthalates, 19 cyanides, 20 and polycyanides 21 have been published.…”
