3,3'-(2,2'-Bi-1H-imidazole-1,1'-di-yl)dipropanamide.

ABSTRACT: In the title compound, C(12)H(16)N(6)O(2), the two imidazole rings are coplanar as a center of inversion exists midway along the C-C bond joining the two rings. In the crystal, inter-molecular N-H?O, N-H?N and C-H?O hydrogen bonds link adjacent mol-ecules into a two-dimensional layer structure parallel to (001).

In the title compound, C(12)H(16)N(6)O(2), the two imidazole rings are coplanar as a center of inversion exists midway along the C-C bond joining the two rings. In the crystal, inter-molecular N-H⋯O, N-H⋯N and C-H⋯O hydrogen bonds link adjacent mol-ecules into a two-dimensional layer structure parallel to (001). ...[more]

Project description:In the title compound, C(12)H(18)N(4)O(2), unlike other unconjugated disubstituted biimidazole derivatives reported so far, the two imidazole rings in a trans conformation exhibit a large planar rotation angle of 51.27?(4)°, and consist of half-mol-ecule asymmetric units related by a twofold rotation.

Project description:The whole mol-ecule of the title compound, C(20)H(18)N(4)O(4), is generated by an inversion center.

Project description:The dinuclear title compound, [Co(2)(C(10)H(8)N(4)O(4))(2)(H(2)O)(4)]·6H(2)O, lies about an inversion centre. Each Co(II) atom is six-coordinated by two water mol-ecules, two carboxyl-ate O atoms and two N atoms of two symmetry-related 2,2'-bi-1H-imidazole-1,1'-diacetate (L(2-)) ligands in a slightly distorted octa-hedral geometry. Mol-ecules are linked into a three-dimensional framework via O-H⋯O and C-H⋯O hydrogen bonds.

Crystal structure of 3,3'-diisopropyl-1,1'-(pyridine-2,6-di-yl)bis-[1H-imidazole-2(3H)-thione].

Project description:In the title compound, C17H21N5S2, the dihedral angles between the central pyridine ring and its pendant imidazole rings are 29.40 (9) and 40.77 (9)°; the pendant rings are twisted in an opposite sense with respect to the central ring. In each case, the S atom is approximately anti to the N atom of the pyridine ring. For both substituents, the H atom attached to the central C atom of the isopropyl group is approximately syn to the S atom in the attached ring. In the crystal, mol-ecules are linked by weak C-H⋯S inter-actions, generating C(5) chains propagating along [001].

Dibromido[1,1'-dibutyl-2,2'-(pentane-1,1-di-yl)di-1H-benzimidazole]-copper(II).

Project description:In the title compound, [CuBr(2)(C(27)H(36)N(4))], the Cu(II) ion exhibits a distorted tetra-hedral coordination geometry provided by two bromide ions and by chelation of two imine N-atom donors from a bis-(benzimidazole) ligand. Chelation results in a six-membered boat-shaped ring which links the benzimidazole groups. Each bis-(benzimidazole) fragment contains three n-butyl substituents, two of which have the expected trans conformation; the third exhibits the higher-energy cis conformation, an orientation consistent with several short intra-molecular C-H⋯Br inter-actions. Essentially planar (r.m.s. deviations of 0.0101 and 0.0183 Å) benzimidazole groups are oriented so as to give the bis-(benzimidazole) fragment a V-shaped appearance in profile with the cis and trans n-butyl groups directed to opposite sides of the planes. In the crystal, columns of mol-ecules along the b-axis direction form layers parallel to the (202) planes. Within a given column, the mol-ecules are linked by C-H⋯Br hydrogen bonds. The mol-ecules in adjacent columns are also linked by inter-molecular C-H⋯π interactions, forming a three-dimensional network.

Poly[[?-2,2'-diethyl-1,1'-(propane-1,3-di-yl)di-1H-imidazole-?N:N](?-5-hy-droxy-isophthalato-?O:O)zinc].

Project description:In the title coordination polymer, [Zn(C(8)H(4)O(5))(C(13)H(20)N(4))](n), the Zn(II) ion is coordinated by an O(2)N(2) donor set in a distorted tetra-hedral geometry. The Zn(II) ions are connected by 5-hy-droxy-isophthalate (hbdc) and 2,2'-diethyl-1,1'-(propane-1,3-di-yl)di-1H-imidazole (pbie) ligands, forming a threefold inter-penetrating diamondoid framework. In the pbie ligand, one of the ethyl-imidazole groups is disordered over two positions, with a site-occupancy ratio of 0.670?(9):0.330?(9). An inter-molecular O-H?O hydrogen bond is formed between the hy-droxy and carboxyl-ate groups of the hbdc ligands.

Poly[[[?-3,3'-(dimethyl-silanedi-yl)dibenzoato][?-1,1'-(1,4-phenyl-ene)di-1H-imidazole]-zinc] monohydrate].

Project description:The asymmetric unit of the title compound, {[Zn(C??H??O?Si)(C??H??N?)]·H(2)O}(n), consists of one Zn(II) ion, two half 3,3'-(dimethyl-silanedi-yl)dibenzoate ligands and two half 1,1'-(1,4-phenyl-ene)di-1H-imidazole ligands. The Zn(II) ion is four-coordinated by two O atoms from two carboxlate ligands, two N atoms from two imidazole ligands. Two Zn(II) ions are bridged by two carboxyl-ate groups in chelating mode, generating a binuclear secondary building unit (SBU), which is further coordinated by two N atoms from two imidazole ligands in monodentate mode. Thus, the binuclear SBUs are further bridged by imidazole ligands in two different directions, giving rise to a chain. The water solvent mol-ecules are hydrogen bonded within the chain along the c axis.

Project description:There are two independent molecules in the asymmetric unit of the title compound, C(25)H(24)F(2)N(6), in which the N=N bonds adopt a trans configuration with distances in the range 1.262 (2)-1.269 (3) Å. The dihedral angles between heterocycles are 86.7 (2) and 85.6 (2)° in the two molecules while the dihedral angles between the heterocylic rings and the adjacent benzene rings are 13.4 (2) and 13.4 (2)° in one molecule and 5.3 (2) and 6.5 (2)° in the other. In the crystal, pairs of independent mol-ecules are held together by four N-H⋯N hydrogen bonds, forming inter-locked dimers.

Project description:The asymmetric unit of the title compound, [Mn(C(6)H(6)N(4))(2)(H(2)O)(2)](C(8)H(4)O(4)), contains one-half each of the centrosymmetric cation and anion.

Inter-molecular N-H?O and O-H?O hydrogen bonds consol-idate the crystal packing, which also exhibits ?-? inter-actions between five-membered rings, with a centroid-centroid distance of 3.409?(2)?Å.
