“…The design of a linker structure between the binding sites permits tuning the properties of the materials based on coordination compounds with multitopic ligands [4][5][6][7]. Applications of functional materials containing such ligands include gas storage [8][9][10], membrane separations [11], electrochemical devices [12], sensing materials [13,14], drug delivery systems [15,16], enantiomer separations [17], and catalysis in fine organic synthesis [18,19].…”

Two binuclear coordination compounds of Cu(II) chloride with the bitopic ligand 1,1,2,2-tetrakis(pyrazol-1-yl)ethane (Pz4) of the composition [Cu2(µ2Pz4)(DMSO)2Cl4]·4H2O and [Cu2(µ2Pz4)(DMSO)2Cl4]∙2DMSO were prepared and characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis, single-crystal X-ray diffraction, and powder diffraction analysis. It was shown that in contrast to silver(I) and copper(II) nitrates, copper(II) chloride forms discrete complexes instead of coordination polymers. The supramolecular structure of the complex [Cu2(µ2Pz4)(DMSO)2Cl4]·4H2O with lattice water molecules is formed by OH···Cl and OH···O hydrogen bonds. Density functional theory (DFT) calculations of vibrational frequencies of the ligand and its copper(II) complex allowed for assigning IR bands to specific vibrations.

“…Because the crystal structure of 2L , which was prepared through the reaction of Zn 2+ and BDC 2– with l -lac 2– , − has been reported previously and 3 is an isomorph of 2 , the structures of 4L and 5L were described. Structural analysis shows that Fe1 is bonded to six oxygen atoms from three different BDC 2– ligands and two deprotonated l -lac 2– ligands and Fe2 is coordinated with six oxygen atoms from three BDC 2– ligands, two l -lac 2– ligands, and one DMF (Figure S2b).…”

Four pairs of chiral 3D coordination polymers (CPs), [Zn2(BDC)(lac)(DMF)]·guest (2) (H2BDC = benzene dicarboxylic acid; H2lac = lactic acid; guest = 1.5DMF + i-PrOH), [Co2(BDC)(lac)(DMF)]·guest (3) (guest = DMF + 2H2O), [Fe4(BDC)3(lac)2(DMF)2](CO3)·guest (4) (guest = DMF + 2H2O), and {Zn11(BPDC)6(lac)6[NH2(CH3)2]2}·guest (H2BPDC = 3,3′-biphenyldicarboxylic acid; guest = 6DMF + 18H2O) (5), are prepared through the reactions of racemic lactic acid (rac-H2lac) with different metal ions and auxiliary ligands. Structural analyses and DFT calculations reveal that forming more and stronger coordination bonds between the auxiliary ligand and metal ions is more conducive to the spontaneous resolution of enantiomers in 3D CPs than simply increasing the entropy of the auxiliary ligand itself.

Nitrilotris(methylenephosphonic)acid N[CH 2 P(O)(OH) 2 ] 3 (H 6 L) reacts with zinc oxide in an aqueous medium to give a poorly soluble polymeric crystalline salt (ZnH 4 L) n . The reaction proceeds through the intermediate formation of a soluble monomer complex ZnH 4 L. The water-soluble amorphous forms of the coordination compound used as microfertilizers were obtained by treatment of a suspension of this salt with 2-aminoethanol, 2-amino-2-(hydroxymethyl)propane-1,3-diol, 2,2´-(ethylenedioxy)bis(ethylamine). p-Aminobenzoic acid H 2 NC 6 H 4 COOH reacts in an aqueous solution with hexabasic nitrilotrimethylenephosphonic acid, as well as with the monomeric complex ZnH 4 L, giving crystals of bis(4-carboxyphenylaminium) nitrilotris(methylenephosphonateThe compounds were investigated by elemental analysis, IR and UV spectroscopy, X-ray phase analysis and X-ray diff raction analysis. Tests of the water-soluble complex with 2-aminoethanol ZnHL 3− •3(H 3 NCH 2 CH 2 OH) + •2H 2 O in the laboratory experiment with seeds of two agricultural crops showed a positive agronomic eff ect.
