The title compound, (EtMe(3)N)(2)[Cd(Se(4))(2)], which has been prepared by reaction of CdI(2), K(2)Se(4) and EtMe(3)NI in dimethyl-formamide, is the first example of a [Cd(Se(4))(2)](2-) anion stabilized by alkyl-ammonium counter-ions. The Cd atom in the complex [Cd(Se(4))(2)](2-) anion is tetra-hedrally coordinated by two chelating tetra-selenide ligands, and both CdSe(4) rings exhibit an env...
SUMMARY Probable synergy has been demonstrated for the com binations of amphotercin B and each of several nifamycin Sv derivatives against nontransformed BALB/3T3 cells and cells transformed with munine sarcoma virus. Synergy also appeared to be present for the combinations of am photericin B and dimethyl formamide on ethanol. The transformed cells were more sensitive to the com binations than ...
The asymmetric unit of the title rare earth coordination polymer, [Ce(C(9)H(3)O(6))(C(3)H(7)NO)(2)](n), contains one eight-coordinated Ce(3+) ion, one benzene-1,3,5-tricarboxyl-ate (BTC) ligand and two coordinated N,N-dimethyl-formamide (DMF) mol-ecules. The Ce(3+) ion is coordinated by six O atoms from four carboxyl-ate groups of the BTC ligands and by two O atoms from two terminal DMF mol-ecu...
DESCRIPTION Zopiclone is a fine white or slightly cream crystalline powder with a melting point of 176-178°C. It is practically insoluble in acetone, soluble in dimethyl formamide and 0.1N hydrochloric acid and freely soluble in chloroform and dichloromethane. Imovane tablets contain 7.5 mg of the active ingredient zopiclone. The tablets also contain lactose, calcium hydrogen phosphate, wheat s...
Sulfation is an important reaction in the biotransformation of steroid hormones, neurotransmitters, drugs, and other xenobiotics, yet little is known about the effects of organic solvents on sulfotransferase (SULT) activities in vitro. Initial experiments found that surprisingly low levels of solvent had dramatic effects on sulfotransferase activity. Consequently, we evaluated the effects of fi...
The solvothermal reaction of Co(NO(3))(2) and 2,4,6-tris(4-pyridyl)-1,3,5-triazine in dimethyl-formamide/ethanol mixed solvent afforded the title coordination polymer, [Co(NO(3))(2)(C(18)H(12)N(6))](n), in which the Co(II) atom is seven-coordinated by pyridyl groups of three different ligands and two chelating nitrate anions. The complex displays a nano-sized porous metal-organic framework that...
Biphenyl-4,4'-dicarb-oxy-lic acid was recrystallized from N,N-dimethyl-formamide (DMF) yielding the title compound, C(14)H(10)O(4)·2C(3)H(7)NO. The acid mol-ecules are located on crystallographic centres of inversion and are hydrogen bonded to DMF mol-ecules. These hydrogen-bonded units form infinite chains although there is no inter-action between the methyl groups of neighboring DMF mol-ecules.
In the title complex, [Fe(C(19)H(12)BrClN(3)O(2))(C(3)H(7)NO)], the Fe(III) atom is coordinated by an N,N,O,O-tetra-dentate Schiff base ligand and trans coordinated by a chloride anion and the O atom of an N,N-dimethyl-formamide mol-ecule. The resulting geometry is distorted octa-hedral within a ClN(2)O(3) donor set.
The title polymeric complex, [HgI(2)(C(10)H(14)N(2))](n), was prepared from a solution of nicotine, mercury(II) iodide and 4-cyano-pyridine in dimethyl-formamide. Each nicotine mol-ecule is bonded to two Hg atoms, one through the pyrrolidine N atom and the other through the pyridine N atom, forming infinite zigzag polymeric chains. The coordin-ation around mercury is completed by two iodide lig...
The title compound, [CoCl(2)(C(11)H(15)N(3)O(2)Si)(2)]·C(3)H(7)NO, was synthesized from 5-nitro-1-trimethyl-silylmethyl-1H-benzimid-azole and cobalt(II) chloride in dimethyl-formamide. The Co(II) atom is coordinated in a distorted tetra-hedral environment by two Cl atoms and two N atoms. In the crystal structure, there are a number of C-H⋯Cl and C-H⋯O hydrogen-bonding inter-actions between symm...
