The title chain polymer compound, [GaLi(2)Br(C(3)H(9)OSi)(4)(C(4)H(8)O)(2)](n), was obtained in the reaction of GaBr(3) with Me(3)SiOLi in toluene/tetra-hydro-furan. The Ga(III) atom, located on a twofold rotation axis, is coordinated by four trimethyl-silanolate ligands and has a distorted tetra-hedral geometry. The Li(I) atom is four coordinated by one bridging Br atom located on an inversion...

A cyclometalated bisruthenium complex bridged by the 2,7-bisdeprotonated form of 1,3,6,8-tetra(pyridin-2-yl)-9-butyl-9H-carbazole displays appreciably enhanced electronic coupling relative to that with the 5,5'-bisdeprotonated form of 3,3',5,5'-tetra(pyridin-2-yl)-biphenyl as the bridge.

The title compound, [CuBr(C(9)H(9)N(5))](n), prepared by the solvothermal treatment of CuBr with 4-(2-allyl-2H-tetra-zol-5-yl)pyridine, is a new homometallic Cu(I)-olefin coordination polymer in which dinuclear Cu(2)Br(2) units are linked by the organic olefin ligand 4-(2-allyl-2H-tetra-zol-5-yl)pyridine, which acts as a bidentate ligand connecting two neighbouring Cu(2)Br(2) units through the ...

In the title complex, [Zn(C(5)H(9)N(4))(2)](n), the Zn(II) center is coordinated by four N atoms of different tetra-zolate ligands with a slightly distorted tetra-hedral geometry [Zn-N distances and N-Zn-N angles are in the ranges 1.991 (2)-2.007 (2) Å and 104.22 (8)-116.13 (8)°, respectively]. Each ligand links two Zn(II) atoms through its 1- and 4-position tetra-zole N atoms, forming a single...

The crystal structure of the title compound, sodium strontium orthoarsenate(V) nona-hydrate, is isotypic with NaSr(PO(4))(H(2)O)(9) and the minerals nabaphite [NaBa(PO(4))(H(2)O)(9)] and nastrophite [Na(Sr,Ba)(PO(4))(H(2)O)(9)]. The Na and Sr atoms are located on threefold rotation axes and are in the centres of slightly distorted Na(H(2)O)(6) octa-hedra and Sr(H(2)O)(9) tricapped trigonal pris...

The title compound, C(14)H(21)Cl(3)O(9)·2H(2)O, is a disaccharide constructed from a galactose and a fructose. In the mol-ecular structure, the tetra-hydro-furan five-membered ring and tetra-hydro-pyran six-membered ring assume envelope and chair conformations, respectively. An extensive O-H⋯O hydrogen-bonding network occurs in the crystal structure.

We report our results on nonlinear optical properties of 2(3), 9(10), 16(17), 23(24) tetra tert-butyl phthalocyanine and 2(3), 9(10), 16(17), 23(24) tetra tert-butyl Zinc phthalocyanine studied using Z-scan technique with 800 nm femtosecond and 532 nm nanosecond pulses. Nonlinear absorption behavior in both femtosecond and nanosecond domains was studied in detail. We observed three-photon absor...
