Poly[chlorido[?(4)-2,2'-(2-methyl-1H-benzimidazol-3-ium-1,3-di-yl)diacetato]-zinc].

ABSTRACT: The title compound, [Zn(C(12)H(11)N(2)O(4))Cl](n), contains a centrosymmetric dimetal tetra-carboxyl-ate paddle-wheel moiety in which the Zn(II) atom is square-pyramidally coordinated by four carboxyl-ate O atoms at the basal positions and one Cl(-) anion at the apical position. Each paddle-wheel unit is joined to four such neighbours through bridging dicarboxyl-ate ligands, producing a two-dimensional undulating layer parallel to (-101). Adjacent sheets are stacked in a parallel fashion to form a three-dimensional supra-molecular structure which is stabilized by inter-layer ?-? inter-actions between benzene rings, with a centroid-centroid distance of 3.722?Å. The range of Zn-O bond lengths is 2.0440?(17)-2.1256?(15)?Å and the Zn-Cl bond length is 2.2622?(6)?Å.

catena-Poly[2-methyl-1H-imidazol-3-ium [(aqua-chloridocadmate)-di-μ-chlorido]].

Project description:The asymmetric unit of the title compound, {(C(4)H(7)N(2))[CdCl(3)(H(2)O)]}(n), contains one 1-methyl-1H-imidazol-3-ium cation, one Cd(II) atom, three Cl atoms and one water mol-ecule. Adjacent Cd ions are inter-connected alternately by paired Cl(-) bridges to generate an infinite one-dimensional coordination chain along the b axis. In the chain, the crystallographically unique Cd(II) atom, with a distorted octa-hedral geometry, is coordinated by five Cl(-) ions and one water mol-ecule. Intra-chain O-H⋯Cl hydrogen bonding and N-H⋯Cl hydrogen bonding between the cations and the anionic chains consolidate the crystal packing.

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.

catena-Poly[bis(1,3-benzo-thia-zol-3-ium) [[di-chlorido-anti-monate(III)]-di-μ-chlorido-μ-oxido-[chlorido-anti-monate(III)]-μ-chlorido]].

Project description:The title compound, {(C7H6NS)2[Sb2Cl6O]} n , contains two benzo-thia-zolidium cations and one tri-μ-chlorido-tri-chlorido-μ-oxido-di-anti-monate(III) anion. The structure of the inorganic cation may be described as as being built up from two polyhedra, i.e. a square-pyramidal SbCl4O and a distorted octa-hedral SbOCl5 unit, sharing a common face (comprising the O atom and two Cl atoms). The two benzo-thia-zole cations are quasi-planar and subtend a dihedral angle of 19.93 (5)°. The crystal packing can be described by alternating (100) layers and [001] chains of the organic cations and inorganic anions connected through an extensive three-dimensional network of N-H⋯Cl, C-H⋯O and C-H⋯Cl hydrogen bonds. This is consolidated by slipped π-π stacking, with centroid-to-centroid distances between the benzo-thia-zole rings of 3.7111 (18)-3.8452 (16) Å. These inter-actions link the mol-ecules within the layers and also link the layers together and reinforce the cohesion of the ionic structure.

Project description:In the title compound, C(24)H(24)N(7) (3+)·3NO(3) (-), the cation exhibits a distorted propeller-like conformation in which the benzimid-azolium fragments form dihedral angles of 9.4 (1), 10.7 (1) and 19.1 (1)° with each other. In the crystal, inter-molecular N-H⋯O hydrogen bonds link cations and anions into double ribbons propagated in [100]. Weak inter-molecular C-H⋯O inter-actions further consolidate the packing.

2-Hy-droxy-methyl-1,3-dimethyl-1H-benzimidazol-3-ium iodide.

Project description:In the cation of the title compound, C10H13N2O(+)·I(-), all non-H atoms, with the exception of the O atom, are essentially coplanar, with a maximum deviation of 0.04?(1)?Å. In the crystal, the cations and anions are arranged in layers parallel to (100). The cations are connected to the anions via an O-H?I hydrogen bond and there are significant ?-? stacking inter-actions between cation layers, with centroid-centroid distances in the range 3.606?(5)-3.630?(5)?Å. A weak intra-molecular C-H?O hydrogen bond is also observed. The crystal studied was an inversion twin with refined components of 0.52?(5) and 0.48?(5).

1,3-Bis(pyridin-2-yl)-1H-benzimidazol-3-ium tetra-fluoridoborate.

Project description:The asymmetric unit of the title compound, C(17)H(13)N(4) (+)·BF(4) (-), contains one half of the benzimidazolium cation and one half of the tetra-fluoridoborate anion, with crystallographic mirror planes bis-ecting the mol-ecules. One F atom of the tetra-fluoridoborate is equally disordered about a crystallographic mirror plane. In the crystal, C-H?F inter-actions link the cations and anions into layers parallel to (100). The crystal packing is further stabilized by F?? contacts involving the tetra-fluoridoborate anions and the five-membered rings [F?centroid = 2.811?(2)?Å].

Crystal structure of catena-poly[1,3-di-benzyl-benzimidazolium [[chlorido-mercurate(II)]-di-?-chlorido]].

Project description:The asymmetric unit of the polymeric title compound, {(C21H19N2)[HgCl3]} n , comprises one-half of the cationic mol-ecule, the other half being generated by application of twofold rotation symmetry, one Hg and two Cl atoms. The Hg(II) atom, lying on a twofold rotation axis, exhibits a distorted triangular coordination environment and is surrounded by three Cl atoms with Hg-Cl distances in the range 2.359?(2)-2.4754?(13)?Å. Two additional longer distances [Hg?Cl = 3.104?(14)?Å] lead to the formation of polymeric [HgCl1/1Cl4/2](-) chains extending along [001]. The crystal packing can be described by cationic layers alternating parallel to (-110) with the anionic chains located between the layers. The packing is consolidated by ?-? stacking inter-actions between the benzene rings of the central benzimidazole entities, with centroid-to-centroid distances of 3.643?(3)?Å.

Project description:In the title compound, {[Zn(C(8)H(5)N(2)O(2)S)(2)]·3H(2)O}(n), the Zn(II) atom, lying on a twofold rotation axis, is four-coordinated by two S atoms and two O atoms from four 2-sulfido-1H-benzimidazol-3-ium-5-carboxyl-ate (H(2)mbidc) ligands in a distorted tetra-hedral geometry. Two H(2)mbidc ligands bridge two Zn(II) atoms, generating a double-chain along [[Formula: see text]01]. Adjacent chains are linked by N-H?O and O-H?O hydrogen bonds, forming a three-dimensional supra-molecular network. One of the two water molecules also lies on a twofold rotation axis.

Project description:The title compound, {(C(13)H(22)N(4))[Ag(2)I(4)]}(n), was prepared by reaction of 1,3-bis-(N-ethyl-imidazolium-1-yl)propane iodide with silver (I) oxide.
