2-(4-Methylsulfanylphenyl)-1H-benzimidazol-3-ium bromide
In the cation of the title compound, C14H13N2S+·Br−, the essentially planar benzimidazole system (r.m.s. deviation = 0.0082 Å) is substituted with a 4-methylsulfanylphenyl ring. The dihedral angle between the benzimidazole system and the 4-methylsulfanylphenyl ring is 2.133 (2)°. The crystal structure is characterized by strong and highly directional intermolecular N—H⋯Br hydrogen bonds involving the bromide ion. Moreover, C—H⋯S interactions result in chains of molecules along the c axis. The supramolecular assembly is further stabilized by π–π stacking interactions between the benzimidazole system and 4-methylsulfanylphenyl rings [centroid–centroid distance = 3.477 (4) Å]
Bis{2-[4-(methylsulfanyl)phenyl]-1H-benzimidazol-3-ium} tetrabromidocuprate(II) dihydrate
The asymmetric unit of the title compound, (C14H13N2S)2[CuBr4]·2H2O, contains two cations, one anion and two solvent water molecules that are connected via O—H⋯Br, N—H⋯Br and N—H⋯O hydrogen bonds into a two-dimensional polymeric structure. The cations are arranged in a head-to-tail fashion and form stacks along [100]. The central CuII atom of the anion is in a distorted tetrahedral environment
Bis{2-[4-(methylsulfanyl)phenyl]-1H-benzimidazol-3-ium} tetrabromidocadmate(II) ethanol monosolvate
In the anion of the title compound, (C14H13N2S)2[CdBr4]·C2H5OH, the CdII atom is in a distorted tetrahedral environment and one of the Br atoms is disordered over three sites with site-occupancy factors of 0.828 (5), 0.106 (3) and 0.068 (4). In the crystal, intermolecular N—H⋯O, C—H⋯O and N—H⋯Br interactions result in a two-dimensional polymeric network extending parallel to (010)
Complexes of the Schiff base derived from 4-aminophenyl benzimidazole and 2, 2'- dehydropyrollidene-N-aldehyde with Zn (II), Cd (II) and Hg (II) halides
2421-2425A new Schiff base, dhpyr4apbi, has been synthesized
from 4-aminophenyl benzimidazole and 2, 2'- dehydropyrollidene-N-aldehyde and its
complexes with Zn (II), Cd (II) and Hg (II) halides have been prepared. Physicochemical
properties of these metal complexes have been investigated using elemental analysis,
molar conductance, proton NMR and IR measurements. The complexes are non-electrolytes
and are dimeric in nature with the
empirical formula M2L2X4
(M = Zn, Cd, Hg; X = Cl, Br.). The minimum energy configurati
on has been obtained for these complexes using the molecular model Pro Plus. All
the compl exes have been screened for their biological activities. The Cd(II) and
Hg(II) complexes show moderate antibacterial activity against Pseudomonas fluorescens.</i
Cationic complexes of palladium(II) containing phosphorus, arsenic, antimony and nitrogen donor ligands
1001-1003Palladium perchlorate reacts with several monodentate tertiary phosphines or arsines in acetonitrile to produce three-coordinate complexes of the type [PdL3[ClO4]2 (L= Ph3P, Ph2EtP, Ph3As, Ph2MeAs, Nap2MeAs, Cy3As, Ph3Sb), while the reaction in tetrahydrofuran leads to four-coordinate complexes of the formula [PdL4][ClO4]2 (L= Ph3P, Ph3As, Ph3Sb). With chelating bidentate ligands, palladium perchlorate yields [Pd(L-L)2][ClO4]2 (L-L= diphos, ɑ-pybzl) complexes
