This study investigates the biological activity of two cationic gemini surfactants, hexamethylene-1,6-bis-(N,N-dimethyl-N-dodecylammonium bromide) C6 and pentamethylene-1,5-bis-(N,N-dimethyl-N-dodecyla,.mmonium bromide) C5, and their two neutral analogs, hexamethylene-1,6-bis-(N-methyl-N-dodecylamine) (A6) and pentamethylene-1,5-bis-(N-methyl-N-dodecylamine) (A5). Experiments were performed wit...

The azide anion is a short bridging ligand that has been used extensively to construct magnetic coordination polymers, and fundamental magneto-structural correlations have been substantiated by theoretical calculations. The copper(II) coordination polymer poly[bis(μ-azido-κ(2)N(1):N(1))(μ4-homophthalato-κ(4)O:O':O'':O''')bis(pyridine-κN)dicopper(II)], [Cu2(C9H6O4)(N3)2(C5H5N)2]n, was synthesize...

THE TITLE COMPOUND [SYSTEMATIC NAME: bis(2,5-dioxo-4,4-diphenylimidazolidin-1-ido-κN(1))bis(ethylenediamine-κ(2)N,N')cobalt(II)], [Co(C(15)H(11)N(2)O(2))(2)(C(2)H(8)N(2))(2)], has site symmetry . The Co(II) cation is located on an inversion center and coordinated by two phenytoin anions and two ethyl-enediamine ligands in a distorted octa-hedral geometry. In the phenytoin anion, the two phenyl ...

The first charge-neutral Lewis base adducts of tin(IV) tetraazide, [Sn(N3)4(bpy)], [Sn(N3)4(phen)] and [Sn(N3)4(py)2], and the salt bis{bis(triphenylphosphine)iminium} hexa(azido)stannate [(PPN)2Sn(N3)6] (bpy = 2,2'-bipyridine; phen = 1,10-phenanthroline; py = pyridine; PPN = N(PPh3)2) have been prepared using covalent or ionic azide-transfer reagents and ligand-exchange reactions. The azides w...

In the crystal structure of the title complex, poly[[diazidomanganese(II)]-di-1,2-bis(imidazol-1-yl)ethaneN:N 0 ], [Mn(N3)2(C8H10N4)2]n or [Mn(N3)2(bim)2]n, where bim is 1,2-bis(imidazol-1-yl)ethane, each Mn atom is six-coordinated in a distorted octahedral coordination environment to four N atoms from four bim ligands and two N atoms from two azide ligands. The Mn atoms, which lie on inversion...

N3 dye molecules [cis-bis(isothiocyanato)bis(2,2'-bipyridyl-4,4'-dicarboxylato)ruthenium(II)] are covalently attached to boron-doped nanocrystalline diamond (B:NCD) thin films through a combination of coupling chemistries, i.e., diazonium, Suzuki, and EDC-NHS. X-ray and ultraviolet photoelectron spectroscopy and near-edge X-ray absorption fine structure spectroscopy are used to verify the coval...
