The title compound, poly[chlorido[mu(4)-2,2'-(2-methylbenzimidazolium-1,3-diyl)diacetato]cadmium(II)], [Cd(C(12)H(11)N(2)O(4))Cl](n), is an undulating two-dimensional polymer consisting of a paddlewheel Cd(2)(CO(2))(4) cluster which lies on an inversion centre. These paddlewheel clusters act as four-connected square building units interlinked via bridging zwitterionic dicarboxylate ligands into a corrugated layer which is consolidated by pi-pi interactions between benzene rings of benzimidazole… Expand

Supramolecular arrays based on dimetal building units.
Characterization of the products by single-crystal X-ray diffraction, CV, DPV, NMR, and other spectroscopic techniques has revealed the presence of discrete tetranuclear (pairs or loops), hexanuclear (triangles), octan nuclear (squares) species and one-, two-, or three-dimensional molecular nanotubes.

Assembly of metal-organic frameworks from large organic and inorganic secondary building units: new examples and simplifying principles for complex structures.
The secondary building unit (SBU) has been identified as a useful tool in the analysis of complex metal-organic frameworks (MOFs). We illustrate its applicability to rationalizing MOF crystalExpand
Transformation of a metal-organic framework from the NbO to PtS net.
Two metal-organic frameworks, MOFs, synthesized and structurally characterized, and their topologies were found to be based on the NbO and PtS nets, which results in the more thermodynamically favored MOF-502. Expand

Three-periodic nets and tilings: semiregular nets.
Three-periodic semiregular nets are defined as those with just one kind of vertex and one kind of edge, but excluding the five regular and one quasiregular nets described earlier. Fourteen of theseExpand
