The asymmetric unit of the title polymeric compound, [Cu(C8H4NO2)2(C10H14N2O)(H2O)] n , contains one Cu(II) atom, one coordinating water mol-ecule, two 4-cyano-benzoate (CB) ligands and one coordinating N,N-di-ethyl-nicotinamide (DENA) mol-ecule. The DENA ligand acts as a bis-monodentate ligand, while the CB anions are monodentate. Two O atoms of the CB ligands, one O atom of the water mol-ecul...

In the title compound, [Gd(C(7)H(5)O(4))(3)(H(2)O)(4)]·2H(2)O, the Gd(III) ion shows a distorted square anti-prismatic coordination formed by four aqua ligands and four O atoms from the three 2,6-dihy-droxy-benzoate (L) ligands. Two L ligands coordinate the Gd(III) ion in a monodentate mode, while the third coordinates it in a bidentate-chelating coordination mode. An extensive three-dimensiona...

The Co(II) atom in the title complex, [Co(NO(2))(2)(C(12)H(12)N(6))(2)](n), lies on an inversion center and is coordinated by four N atoms from the triazole rings of two symmetry-related pairs of 1,4-bis-(1,2,4-triazol-1-ylmeth-yl)benzene (bbtz) ligands and two O atoms from two symmetry-related monodentate nitrate ligands in a distorted octa-hedral geometry. The Co atoms are bridged by four bbt...

Information on the binding of organic ligands to metal (hydr)oxide surfaces is useful for understanding the adsorption behaviour of natural organic matter on metal (hydr)oxide. In this study, benzoate and salicylate were employed as the model organic ligands and aluminum hydroxide as the metal hydroxide. The attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectra revealed tha...

In the title complex, di-aqua-(1H-imidazole-κN3)(nitrato-κ2O,O')bis-(4-oxo-pent-2-en-2-olato-κ2O,O')lanthanum(III), [La(C5H7O2)2(NO3)(C3H4N2)(H2O)2], the La atom is coordinated by eight O atoms of two acetyl-acetonate (acac) anions acting as bidentate ligands, two water mol-ecule as monodentate ligands, one nitrate anions as a bidentate ligand and one N atom of an imidazolate (ImH) molecule as ...

In the mol-ecule of the title compound, [CdCl(2)(C(24)H(20)N(2))(2)], the Cd(II) centre has a distorted tetra-hedral coordination geometry defined by two chloride ions and two pyridine N atoms of the monodentate 2-[(triphenyl-meth-yl)amino]pyridine ligands. Weak intra-molecular N-H⋯Cl hydrogen bonds help to establish the three-dimensional architecture.

In the title complex, [Cu(C(15)H(11)BrN(2)O(3))(C(5)H(5)N)], the central Cu(II) atom is in a square-planar CuN(2)O(2) coordination environment formed by the tridentate hydrazone and the monodentate pyridine ligands with N atoms in a trans-arrangement about the Cu(II) atom.

Monodentate phosphoramidite ligands are used to accelerate the copper(i)-catalyzed 1,3-dipolar cycloaddition of azides and alkynes (CuAAC) rapidly yielding a wide variety of functionalized 1,4-disubstituted-1,2,3-triazoles; Cu(i) and Cu(ii) salts both function as the copper source in aqueous solution to provide excellent yields.

In the title compound, [Ni(NO(3))(2)(C(24)H(20)N(2))(2)], the Ni(II) atom has a distorted pseudo-octa-hedral coordination geometry defined by two chelating nitrate groups and two pyridine N atoms of the monodentate N-(triphenyl-meth-yl)pyridin-2-amine ligands. Intra-molecular N-H⋯O hydrogen bonds help to establish the configuration.

In the mol-ecule of the title compound, [Sb(C(7)H(11)OS(2))(3)], the anti-mony(III) is coordinated by the S atoms of three O-alkyl xanthate groups acting as monodentate ligands, forming a distorted trigonal-pyramidal coordination.
