Hexa-kis-(1H-imidazole-?N)iron(II) sulfate-1H-imidazole (1/2).

ABSTRACT: The asymmetric unit of the title compound, [Fe(C(3)H(4)N(2))(6)]SO(4)·2C(3)H(4)N(2), contains two complex cations, two sulfate anions and four imidazole mol-ecules. In both cations, the Fe(II) atom is coordinated by six monodentate imidazole ligands and exhibits a slightly distorted octa-hedral coordination geometry. The Fe-N distances [2.184?(4)-2.218?(4)?Å] point to a high-spin state of the Fe(2+) ions. N-H?O hydrogen bonds between the ionic components generate a three-dimensional framework containing corrugated channels along [001], which are filled by N-H?N hydrogen-bonded imidazole chains.

trans-Tetra-kis(1-allyl-1H-imidazole-κN)bis-(thio-cyanato-κN)nickel(II).

Project description:The structure of the title compound, [Ni(NCS)(2)(C(6)H(8)N(2))(4)], consists of isolated mol-ecules of [Ni(NCS)(2)(Aim)(4)] (Aim = 1-allyl-imidazole), which contain a distorted octa-hedral NiN(6) chromophore. The NCS(-) anions are trans and four N atoms from the 1-allyl-imidazole ligands define the equatorial plane. The mean Mn-N(Aim) and Mn-N(NCS) distances are 2.105 (2) and 2.098 (2) Å, respectively. Weak C-H⋯N inter-actions contribute to the crystal packing stability.

Bromidotetra-kis-(1H-2-ethyl-5-methyl-imidazole-κN)copper(II) bromide.

Project description:The Cu(II) ion in the title compound, [CuBr(C(6)H(10)N(2))(4)]Br, is coordinated in a square-based-pyramidal geometry by the N atoms of four imidazole ligands and a bromide anion in the apical site. Both the Cu(II) and Br(-) atoms lie on a crystallographic fourfold axis. In the crystal, the [CuBr(C(6)H(10)N(2))(4)](+) complex cations are linked to the uncoordinated Br(-) anions (site symmetry [Formula: see text]) by N-H⋯Br hydrogen bonds, generating a three-dimensional network. The ethyl group of the imidazole ligand was modelled as disordered over two orientations with occupancies of 0.620 (8) and 0.380 (8).

Project description:In the title compound, [Mn(C(10)H(10)N(2))(6)](ClO(4))(2), the Mn(II) ion, located on an inversion center, is coordinated by six N atoms from three pairs of symmetry-related 1-benzyl-1H-imidazole ligands in a distorted octa-hedral geometry. In the crystal, weak inter-molecular C-H?O hydrogen bonds link the complex cations and perchlorate anions.

Dibromidotetra-kis(1H-indazole-κN)copper(II).

Project description:The Cu atom in the title compound, [CuBr(2)(C(7)H(6)N(2))(4)], is surrounded by four N-heterocycles that define an N(4) square-planar geometry. The coordination geometry is distorted towards an elongated octa-hedron owing to the presence of the two Br(-) anions, which are located at about 3 Å above and below the square plane. There are two independent molecules in the asymmetric unit, each with their Cu atom lying on an inversion centre.

Hexakis(1H-imidazole-κN)mangan-ese(II) triaqua-tris(1H-imidazole-κN)manganese(II) bis-(naphthalene-1,4-dicarboxyl-ate).

Project description:In the crystal structure of the title compound, [Mn(C(3)H(4)N(2))(6)][Mn(C(3)H(4)N(2))(3)(H(2)O)(3)](C(12)H(6)O(4))(2), there are uncoordinated naphthalene-dicarboxyl-ate dianions and two kinds of Mn(II) complex cations, both assuming a distorted octa-hedral geometry. One Mn(II) cation is located on an inversion center and is coordinated by six imidazole mol-ecules, while the other Mn(II) cation is located on a twofold rotation axis and is coordinated by three water mol-ecules and three imidazole units. The naphthalene-dicarboxyl-ate dianions are linked to both Mn(II) complex cations via O-H⋯O and N-H⋯O hydrogen bonding, but no π-π stacking is observed between aromatic rings in the crystal structure.
