Metal–organic frameworks based on multicarboxylate linkers

A Structural Survey of Poly-Functional Dithiocarbamate Ligands and the Aggregation Patterns They Sustain

“…The structure of each of the next four palladium(II) complexes to be described adopts the di-nuclear structural motif illustrated in Figure 4b. Thus, Pd 2 (L 6 ) 2 (15) [38] is centrosymmetric as for 8. When the same molecule was isolated as its chloroform mono-solvate, in 16 [38], it lacks the crystallographic symmetry of 15, but it adopts essentially the same conformation.…”

“…The importance of dithiocarbamate ligands in coordination chemistry notwithstanding, their use in expanding the burgeoning field of metal organic frameworks (MOFs) and coordination polymers is quite plainly lagging compared with, for example, the ubiquitous carboxylates [15]. This is not to suggest there is no role for sulphur in extended framework assemblies.…”

Synthesis and structure of a new fluorescent sensor based on Ba(II)‐multicarboxylate for detection of Cu2+ ion

“…And the treatment of high-concentration heavy metal ions with high toxicity were studied as the focus. [1][2][3][4] Copper is the third most abundant transition metal ion in human body after iron ion and zinc ion, and is also an essential trace element for human body. Excessive copper will have toxic effects on the central nervous system, cardiovascular system and hematopoietic function, which will harm human health and even lead to death.…”

“…With the improvement of people‘s awareness of environmental protection, heavy metal pollution has brought people‘s attention to the problems of people‘s living environment. And the treatment of high‐concentration heavy metal ions with high toxicity were studied as the focus [1–4] . Copper is the third most abundant transition metal ion in human body after iron ion and zinc ion, and is also an essential trace element for human body.…”

“…The structure of Ba(II)-CP 1 contains three kinds of polyhedra, double-capped triangular prism [Ba(1)O 7 N] made up of octa-coordinated Ba(1) ion, single-capped tetragonal antiprism [Ba(2)O 9 ] built from nona-coordinated Ba(2) ion and pentagonal bipyramid [Ba(3)O 6 N] constructed by Ba(3) ion. [Ba(1)O 7 N] polyhedron is connected to [Ba(2)O 9 ] polyhedron in face-shared way (O(2)À C(7)À O(13)), and [Ba(2)O 9 ] polyhedron is linked with [Ba(3)O 6 N] polyhedron in edge-shared manner (O(8)À O(10)), to pose the secondery building unit (SBU) [Ba(1)…”
