2,6-Bis(1,2,3-triazol-4-yl)pyridine (btp) is a terdentate binding motif that is synthesised modularly via the CuAAC reaction. Herein, we present the synthesis of ligands 1 and 2 and the investigation of the coordination chemistry, photophysical behaviour and electrochemistry of complexes of these with a number of d-metal ions (e.g. Ru(II), Ir(III), Ni(II) and Pt(II)). The X-ray crystal structur...

Herein in this article, three new Ca(II), Zn(II) and Au(III) complexes of sulfamethoxazole (SZ) (sulfa-drug) have been synthesized for the first time. The sulfa-drugs have a great attentions because of their therapeutic applications against bacterial infections. The SZ complexes were discussed with the help of elemental analyses, molar conductance and spectroscopic instruments e.g. IR, 1H-NMR, ...

In the title complex, [Zn(C(10)H(8)N(5))Cl](n), the Zn(II) ion is four-coordinated by one Cl atom and three N atoms from two in situ-generated deprotonated 5-(1-methyl-1H-benzimidazol-2-yl-κN(3))-1,2,3-triazol-1-ide ligands in a slightly distorted tetra-hedral geometry. The Zn(II) ions are bridged by the ligands, forming a helical chain along [001]. C-H⋯N and C-H⋯Cl hydrogen bonds and π-π inter...

In the crystal structure of the title compound, [Cu(C(2)H(3)O(3))Cl(H(2)O)](n), the Cu(II) ion is five-coordinate in a distorted square-pyramidal geometry. Two O atoms from a chelating glycolate anion, an O atom from a coordinated water mol-ecule and a chloride anion comprise the basal plane. A chloride ion from a neighbouring unit occupies the apical position and these Cu-Cl-Cu bridges link th...

The title compound, cis-[RuCl(2)(C(3)H(9)P)(4)]·2C(6)H(6), contains a complex mol-ecule with a crystallographic mirror plane passing through the Ru(II) atom, the two cis-disposed Cl ligands and two P atoms of the two cis-disposed P(CH(3))(3) ligands. The Ru(II) atom adopts a distorted octa-hedral RuCl(2)P(4) coordination geometry with the two trans-disposed P atoms occupying the axial positions...

The title compound, [Zn(CH(3)CO(2))Cl(C(14)H(14)N(4))](n), is a one-dimensional coordination polymer in which the Zn(II) ion is tetrahedrally -coordinated by two N atoms of a bridging 1,1'-[1,4-phenyl-enebis(methyl-ene)]di-1H-imidazole ligand, an acetate O atom and a Cl atom. The Cl atom, two acetate O atoms and two acetate C atoms are located on a mirror plane. The coordination of the diimidaz...

The title compound, [Cu(C(2)Cl(3)O(2))(2)(C(3)H(4)N(2))(4)], was prepared by the reaction of imidazole and trichloro-acetatocopper(II). The Cu(II) atom adopts a distorted octa-hedral coordination geometry, binding the N atoms of four imidazole ligands and the carboxyl-ate O atoms of two trichloro-acetate anions. The mol-ecular structure and packing are stabilized by N-H⋯O hydrogen-bonding inter...

The Zn(II) atom in the title complex, [ZnCl(2)(C(8)H(12)N(4))], is coordinated by two Cl atoms and three N atoms of the N-[1-(pyrazin-2-yl)ethyl-idene]ethane-1,2-diamine ligand, and displays a distorted square-pyramidal geometry with the apical position occupied by a Cl atom. In the crystal, inter-molecular N-H⋯Cl and C-H⋯Cl hydrogen bonds link the mol-ecules into a three-dimensional framework.

A new set of Ru-Cl complexes containing either the pinene[5,6]bpea ligand (L1) or the C3 symmetric pinene[4,5]tpmOMe (L2) tridentate ligand in combination with the bidentate (B) 2,2'-bipyridine (bpy) or 1,2-diphenylphosphinoethane (dppe) with general formula [RuCl(L1 or L2)(B)](+) have been prepared and thoroughly characterized. In the solid state, X-ray diffraction analysis techniques have bee...
