Abstract Hydrothermal synthesis, crystal structure and properties of a new heterometallic coordination polymer [(VO(terpy)) 4 (MoO ) 2 (Mo 8 O 26 )]·2H ( 1 (terpy = 2,2′;6′,2″-terpyridine) are reported. Compound contains two crystallographically unique vanadium(IV) atoms, bonded to terminal oxido ligand further coordinated terpy ligand. The three N atoms occupy the meridional sites distorted {V...

Using a group of six neutral M(II)Cl(2)-containing coordination compounds as building blocks, the first systematic investigation of C-H...Cl hydrogen-bonding interactions was performed. Single-crystal X-ray structural analyses of four new compounds (pseudo-tetrahedral Co(II) and Zn(II); distorted trigonal bipyramidal Zn(II)) authenticate the metal coordination geometry. To provide a unified vie...

The segmental ligand 2-[6-(N,N-diethylcarbamoyl)pyridin-2-yl]-1,1'-dimethyl-5,5'-methylene-2'-(6-methylpyridine-2-yl)bis[1H-benzimidazole] (L3) reacts with a stoichiometric mixture of LnIII (Ln = La, Eu, Gd) and M(II) (M = Zn, Fe) in acetonitrile to produce selectively the heterodimetallic triple-stranded helicates (HHH)-[LnM(L3)3]5+. In these complexes, M(II) is pseudooctahedrally coordinated ...

Ruthenium(ii) complexes of PQQTME, a trimethyl ester derivative of redox-active PQQ (pyrroloquinolinequinone), were prepared using a tridentate ligand, 2,2':6',2''-terpyridine (terpy) as an auxiliary ligand. The characterization of the complexes was performed by spectroscopic methods, X-ray crystallography, and electrochemical measurements. In one complex, the pyridine site of PQQTME binds to t...

The facile synthesis of a new 3-hydroxyadamantyl-functionalized N-heterocyclic carbene (NHC) ligand and its corresponding rhodium complex [Rh(NHC)(COD)Cl] is described. This features an unusually large yaw distortion angle (θ = 6.8°) for monodentate NHC species, which attributed to unsymmetrical nature the steric imbalance between two wingtips. comprehensive analysis angles in 85 related Rh spe...

The title compound, [Fe(2)(C(5)H(5))(2)(C(21)H(21)N(3)O(2))], a potential novel N,N',N''-tridentate ligand with (non-crystallographic) C(2) axial symmetry, adopts a U-shaped molecular conformation.

In the title compound, [PdCl(C(34)H(33)P(3))]PF(6), the Pd(II) atom adopts a distorted PdP(3)Cl square-planar geometry arising from the P,P',P''-tridentate triphos ligand and a chloride ion.

Titanium complexes bearing an unprecedented tridentate cyclopentadienyl-silsesquioxanate ligand provide a new class of efficient and selective catalysts for epoxidation of olefins with aqueous hydrogen peroxide under homogeneous conditions.

A series of coordination compounds have been prepared with tridentate Schiff base ligands, 2 ethyl-[(hydroxy propyl)]3, 1 (4H) quinazoline4-semicarbazone [EHPQS) and 2-ethyl-[(hydroxy propyl)]3, 1 (4H) quinazoline4-thiosemicarbozone [EHPQT]. The obtained complexes were characterized by molar mass, elemental analysis, infrared spectra, electronic spectra, magnetic susceptibility molar conductanc...

In the title cocrystal, [Ni(C(11)H(10)N(3)O(2))(2)]·[Ni(NCS)(2)(C(11)H(11)N(3)O(2))(H(2)O)], both Ni(II) ions are in disorted octa-hedral coordination environments. One Ni(II) ion is coordinated by four N atoms and two O atoms from two tridentate 6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinate (DPP) ligands, while the other Ni(II) ion is coordinated by a tridentate 6-((3,5-dimethyl-1H-pyrazol-1-yl))...
