New coordination polymer of [HgLCl2]n (1) with HgCl2 and Schiff base bidentate ligand (4-methoxyphenyl) pyridine-2yl methyleneamine (L) was prepared and structurally characterized. In the 1D network structure of 1, the mecury (II) ion adopts an HgN2Cl3 distorted square pyramid geometry. In this complex, one of the chlorine acts as bridging ligand connecting two adjacent mercury(II) ions while, ...

The Dinuclear Cu (II) complex [{CuCl}2(μ – tppz)](PF6)2, where tppz represents tetra-2-pyridinylpyrazine, has been prepared and characterized by elemental analysis, 1H-NMR, IR and UV-vis spectroscopies. A crystal structure of the complex showed the Cu (II) are surrounded by three N atoms of tppz bridging ligand and one Cl atom. Crystal structure data are as follows: crystal system monoclinic, s...

The title dinuclear titanocene, [Ti(2)(C(8)H(9)O)(C(18)H(25)Si)(2)Cl(3)O], contains one Ti atom tetra-hedrally coordinated by two Cl atoms, a bridging O atom and the substituted cyclo-penta-dienyl ligand, and another Ti atom tetra-hedrally coordinated by a Cl atom, a bridging O atom, the 2,6-dimethyl-phenolate ligand and the substituted cyclo-penta-dienyl ligand. The bridging O atom lies on a t...

Highly efficient photoswitching tetranuclear rhenium(I) tricarbonyl diimine complexes with a stilbene-like bridging ligand are reported. The ability to directly populate excited states localized on the bridging ligand is the key for the observed efficient photoisomerization.

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...
