چکیده
A terpyridine ligand is covalently linked to a hexamolybdate cluster through the Mo-N imido bond, paving the way for the preparation of hybrids containing covalently bonded transition metal complexes and polyoxometalate clusters.

Functionalized polyoxometalates with intrinsic photochromic properties and their association with spiropyran cations.
The presence of alkylammonium groups covalently grafted on bisphosphonato ligands induces photochromic properties to ligand-coordinated polyoxomolybdate systems. Such intrinsically photoactive polyanions can be used for the preparation of materials combining photochromic polyoxometalates and functional countercations.
متن کاملAn Investigation of Z-in Distortion in Mononuclear Cu(II) Complex with Terpyridine Ligands, [Cu(terpy)2](PF6)2
The first crystal structure of [Cu(terpy)2](PF6 )2 , where terpy=2,2':6',2"-terpyridine is reported. Green crystals of [Cu(terpy)2](PF6 )2 were grown by ether diffusion into an acetonitrile solution of the complex. Crystal structure of this complex is tetragonal ( space group: P21c ...
متن کاملμ-Adipato-bis[chlorido(2,2′:6′,2′′-terpyridine)copper(II)] tetrahydrate
In the title compound, [Cu(2)(C(6)H(8)O(4))Cl(2)(C(15)H(11)N(3))(2)]·4H(2)O, the dinuclear copper complex is located on a crystallographic inversion centre. Each Cu atom is in a distorted square-pyramidal coordination environment, with one O atom of an adipate dianion and three N atoms from the 2,2':6',2''-terpyridine ligand occupying the basal plane, and one chlorine in the apical site. In add...
متن کاملFrom 4'-Hydroxy-2,2':6',2''-Terpyridine Complex of Chromium(III) towards Cr2O3 Nanoparticles: Effects of the Calcination Temperature on the Particle Size and Morphology
A new chromium(III) complex containing 4ʹ-hydroxy-2,2ʹ:6ʹ,2ʺ-terpyridine (tpyOH) has been prepared by the reaction of CrCl3. 6H2O with tpyOH in the presence of metallic zinc to afford the new complex [CrCl3(tpyOH)] (1). The complex 1 was used as a suitable precursor for the preparation of Cr2O3 nanoparticles by the simple calcination method at three different annealed temperatures of 400, 600, ...
متن کاملYellow-light sensitization of a ligand photosubstitution reaction in a ruthenium polypyridyl complex covalently bound to a rhodamine dye.
The ruthenium complex [Ru(terpy)(bpy)(Hmte)](2+) ([1](2+)), where terpy is 2,2';6',2''-terpyridine, bpy is 2,2'-bipyridine, and Hmte is 2-methylthioethan-1-ol, poorly absorbs yellow light, and although its quantum yield for the photosubstitution of Hmte by water is comparable at 570 nm and at 452 nm (0.011(4) vs. 0.016(4) at 298 K at neutral pH), the photoreaction using yellow photons is very s...
