In the title manganese(III) complex, [MnCl(2)(C(10)H(24)N(4))]BF(4) or trans-[MnCl(2)(cyclam)]BF(4) (cyclam is the tetra-dentate amine ligand 1,4,8,11-tetra-azacyclo-tetra-deca-ne), the Mn(III) ions occupy the center of a distorted octa-hedron coordinated by all four ligand nitro-gen donors in the macrobicyclic cavity and two chloride ions occupy the axial positions. Intra-molecular hydrogen bo...

maleic anhydride (man) copolymers with methyl methacrylate(mma), ethyl methacrylate(ema), methyl acrylate(ma), ethyl acrylate (ea) and buthyl acrylate (ba) ( in a 1:1 mole ratio) were synthesized by free radical polymerizations method under vacuum -azobis(isobutironitrile)(aibn) as an initiator of reaction at 701c. the copolymer compositions were determined using related 1h nmr spectra techni...

Magnetic modification of microbial cells enables to prepare smart biocomposites in bioremediation. In this study, we constructed an efficient biocomposite by assembling Fe3O4 nanoparticles onto the surface of Sphingomonas sp. XLDN2-5 cells. The average particle size of Fe3O4 nanoparticles was about 20 nm with 45.5 emu g-1 saturation magnetization. The morphology of Sphingomonas sp. XLDN2-5 cell...

The title compound, C13H21NO7 {systematic name: (3aR,5S,6R,6aR)-5-[(R)-2,2-dimethyl-1,3-dioxolan-4-yl]-2,2-dimethyl-6-(nitro-meth-yl)tetra-hydro-furo[2,3-d][1,3]dioxole}, consists of a substituted 2,2-di-methyl-tetra-hydro-furo[2,3-d][1,3]dioxolane skeleton. The furan-ose ring A adopts a (o)T 4 conformation. The fused dioxolane ring B and the substituent dioxolane ring C also have twisted confo...

In the title mononuclear complex, [Zn(C(7)H(4)NO(4))(2)(C(8)H(8)N(2)S)(2)], the Zn(II) atom is coordinated by two N atoms from two 2-amino-6-methyl-1,3-benzothia-zole and by two carboxylate O atoms from two 4-nitro-benzoate ligands, adopting a slightly distorted tetra-hedral coordination geometry. In the crystal, inter-molecular N-H⋯O hydrogen bonds between the amino group of 2-amino-6-methyl-1...

In the title complex, [Zn(2)(C(8)H(3)NO(6))(2)(CH(4)N(2)S)(4)]·2H(2)O, the carboxyl-ate groups of the 3-nitro-phthalate ligands coordinate in a bis-monodentate mode to the Zn(II) cations. This results in the formation of a centrosymmetric dimer containing two Zn(II) cations with distorted tetra-hedral geometries provided by the O atoms of two different 3-nitro-phthalate dianions and the S atoms...

The title compound, C(26)H(34)NSi(2) (+)·Cl(-), shows chirality at silicon. Because of its highly selective synthesis with an e.r. of >99:1 by means of a racemic resolution with mandelic acid, the free disilane is of great importance to the chemistry of highly enanti-omerically enriched lithio-silanes and their trapping products. N-H⋯Cl hydrogen bonding is present between the protonated nitro-g...

In this work, we present a study on series of recently synthesized indole derived compounds that were previously suggested by experimental tests as having herbicidal action. Density functional theory (DFT) and its time-dependent formalism (TD-DFT) used for investigating ground excited state properties, respectively. The M06-2X CAM-B3LYP exchange-correlation with the aug-cc-pVTZ basis set. Compu...
