The coordination geometry of the Cd(II) atom in the title complex, [Cd(NCO)(2)(C(10)H(14)N(4))(2)](n) or [Cd(NCO)(2)(bimb)(2)](n), where bimb is 1,4-bis-(imidazol-1-yl)butane, is distorted octa-hedral with the Cd(II) atom located on an inversion center and connected to four N atoms from the imidazole units of four symmetry-related bimb ligands and two O atoms from two symmetry-related NCO(-) li...

The crystal structure of the title compound, (C(23)H(33)N(2))[FeCl(4)], consists of 1,3-bis-(1-adamant-yl)imidazolium (BAIM) cations and tetra-hedral tetra-chloridoferrate(III) (TCF) anions. The BAIM cation possesses m symmetry, with the central imidazole ring and four C atoms of each terminal adamantyl group located on a mirror plane. The Fe and two Cl atoms of the TCF anion are also located o...

The title hydrated complex, [Zn2Cl4(C9H12N4)2]·2H2O, is a discrete dinuclear zinc complex with 1,3-bis-(1H-imidazol-1-yl)propane as the bridging ligand. The complex mol-ecule lies about a crystallographic inversion centre. The Zn(II) atom exhibits a distorted tetra-hedral coordination geometry defined by two imidazole N atoms and two Cl atoms. O-H⋯Cl hydrogen bonding between the lattice water m...

Two new molecular structures, namely 1,3-bis(trimethylsilyl)-1H-benzimidazole-2(3H)-thione, C13H22N2SSi2, (2), and 1-trimethylsilyl-1H-benzimidazole-2(3H)-thione, C10H14N2SSi, (3), are reported. Both systems were derived from 1H-benzimidazole-2(3H)-thione. Noncovalent C-H···π interactions between the centroid of the benzmidazole system and the SiMe3 groups form helicoidal arrangements in (2). D...

In the title compound, [MnCl(2)(C(11)H(13)N(5))], the Mn(II) ion is five-coordinated in a distorted square-pyramidal geometry, with three N atoms from the neutral tridentate 2,6-bis-(4,5-dihydro-1H-imidazol-2-yl)pyridine ligand and one chloride ion forming the basal plane and the other chloride ion in the apical position. Both dihydro-imidazole rings adopt envelope conformations. In the crystal...

The reaction of hexafluorothioacetone dimer (2,2,4,4-tetrakis(trifluoromethyl)-1,3-dithiethane, 1) with vinylamides leads to the rapid formation of [2 + 2] cycloadducts: 4-amino-2,2-bis(trifluoromethyl)thietanes. The reaction proceeds in polar solvents (DMF, DMSO) in the absence of a catalyst at elevated temperature producing the corresponding cycloadducts in 47-86% yield. The reaction of N-vin...

The title compound, C(17)H(19)N(4) (+)·Br(-), is built up from 1,3-bis-[(6-methyl-2-pyridin-yl)meth-yl]imidazolium cations and bromide anions. Each of two 6-methyl-2-pyridyl rings is rotated out of the imidazole plane, making dihedral angles of 79.90 (9) and 86.40 (9)°. The packing is consolidated by aromatic π-π inter-actions between the pyridine rings of neighbouring mol-ecules [centroid-cent...

In the title one-dimensional coordination polymer, [ZnCl(2)(C(12)H(10)N(4))](n), the Zn(II) atom (site symmetry 2) is coordinated by two chloride ions and two 1,4-bis-(imidazol-1-yl)benzene ligands, generating a distorted tetra-hedral ZnCl(2)N(2) geometry for the metal ion. The bridging ligand, which is completed by crystallographic inversion symmetry, links the Zn(II) atoms into zigzag chains ...

The asymmetric unit of the title complex, [Hg(C(11)H(12)N(2))(2)](PF(6))(2), consists of one bis-(1-benzyl-3-methyl-imidazolium)mercury(II) cation, one half of the cation and an additional Hg(II) atom, which lies on an inversion centre, and three hexa-fluorido-phosphate anions. The Hg(II) atoms exist in a linear coordination geometry [C-Hg-C = 178.9 (2) and 180°] formed by two carbene C atoms f...
