“…Another very closely-spaced, head-to-head pair of CO 3 2− ions (C···C: 3.664(1), O···O: 1.946(1) Å) has been reported in which both CO 3 2− ions are bound to multiple metal centers [ 21 ]. The tetranuclear Cu 4 ( μ 4 -CO 3 ) moiety has also been reported with a few other ligand systems [ 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ].…”

Anion binding and extraction from solutions is currently a dynamic research topic in the field of supramolecular chemistry. A particularly challenging task is the extraction of anions with large hydration energies, such as the carbonate ion. Carbonate-binding complexes are also receiving increased interest due to their relevance to atmospheric CO2 fixation. Nanojars are a class of self-assembled, supramolecular coordination complexes that have been shown to bind highly hydrophilic anions and to extract even the most hydrophilic ones, including carbonate, from water into aliphatic solvents. Here we present an expanded nanojar that is able to bind two carbonate ions, thus doubling the previously reported carbonate-binding capacity of nanojars. The new nanojar is characterized by detailed single-crystal X-ray crystallographic studies in the solid state and electrospray ionization mass spectrometric (including tandem MS/MS) studies in solution.

“…21 In addition to these five dative interactions, the copper atoms interact with one oxygen atom (O8) belonging to the adjacent nitrate ions at a long distance (2.888(2) Å) to complete its pseudo-octahedral geometry. Searching the CSD database reveals that there are 10 analogues for complex 2 (all structures containing the base presented in Figure 3; structures containing N 3 -donor macrocyclic ligands were omitted for precise results) [64][65][66][67][68][69][70][71][72] with τ value in the range of 0.02−0.36 and square-pyramidal geometry. In all structures the ligands are coordinated in mer form, and based on the ligand direction, these analogues have two isomeric forms which are presented in Figure 3.…”

Two complexes of N1-(2-aminoethyl)propane-1,3-diamine (AEPD), [Ni(AEPD)2](NO3)2 (1) and [Cu2( μ-Cl)2(AEPD)2](NO3)2·2H2O (2), are prepared and identified by elemental analysis, Fourier transform infrared spectroscopy and UV–Vis spectroscopy, and single-crystal X-ray diffraction (for 2). Spectral and structural data reveal that the AEPD ligand transfers from nickel to copper in the reaction between 1 and copper chloride. All coordination modes of the AEPD-based ligands are studied by analysis of the Cambridge Structural Database. The nickel atom in 1 has octahedral geometry (NiN6) while X-ray structure analysis revealed that the copper atom in the binuclear structure of 2 has an elongated square-pyramidal geometry with a CuN3OCl2 environment. In the crystal network of 2, water molecules and cationic complex units along with the nitrate ions form different hydrogen bond motifs. The thermodynamic stability of the compounds and their charge distribution patterns is studied by density functional theory and natural bond orbital analysis. The ability of AEPD and its complexes to interact with 10 selected biomacromolecules is investigated by docking calculations.

N,N9-bis(3-aminopropyl)-3-pyridylmethylamine (bapa) has been synthesized as a building block for coordination polymers, and its coordination polymer {[Cu(bapa)(MeCN)][Cu(bapa)(ClO 4 )] (ClO 4 ) 3 ?MeCN} ' (1) was obtained by reacting it with Cu(ClO 4 ) 2 ?6H 2 O in MeCN solution. In addition, three macrocyclic coordination polymers, {), were obtained by the condensation between bapa and N,N9-bis(3formyl-5-methylsalicylimine)-1, 2-propylenediimine for 2 and 3, and N,N9-bis(3-formyl-5methylsalicylidene)-1,2-ethylenediimine for 4 in the presence of Cu(II), Mn(II) and Cu(II), respectively. These polymers have the common feature that the 3-methylaminopyridine group in one ligand coordinates to the metal ion in the neighboring coordination unit, leading to the formation of a one-dimensional infinite chain. There are abundant hydrogen bonds in each of the complexes, involving water clusters and perchlorate anions.
