Crystal structure of poly[tetra-?-cyanido-ethanol-bis(2-iodo-pyrazine)-digold(I)iron(II)].

ABSTRACT: In the title polymeric complex, [Au₂Fe(CN)₄(C₄H₃IN₂)₂(C₂H₆O)] _n , the Fe^II cation is coordinated by two iodo-pyrazine mol-ecules, one ethanol mol-ecule and three di-cyano-aurate anions in a distorted N₅O octa-hedral geometry. In the crystal, the di-cyano-aurate anions bridge the Fe^II cations to form polymeric chains propagating along the b-axis direction. Stabilization of the crystal structure is provided by O-H?N hydrogen bonds and ?-? stacking between parallel iodo-pyrazine rings of neighbouring chains, the centroid-centroid distances being 3.654?(10) and 3.658?(9)?Å.

Project description:In the title polymeric complex, {[Fe(CN)2(C10H8N2)2(H2O)2][Au(CN)2]} n , the FeII ion, which is located on a twofold rotation axis, has a slightly distorted FeN4O2 octa-hedral geometry. It is coordinated by two phenyl-pyrazine mol-ecules, two water mol-ecules and two di-cyano-aurate anions, the Au atom also being located on a second twofold rotation axis. In the crystal, the coordinated di-cyano-aurate anions bridge the FeII ions to form polymeric chains propagating along the b-axis direction. In the crystal, the chains are linked by Owater-H⋯Ndi-cyano-aurate anions hydrogen bonds and aurophillic inter-actions [Au⋯Au = 3.5661 (3) Å], forming layers parallel to the bc plane. The layers are linked by offset π-π stacking inter-actions [inter-centroid distance = 3.643 (3) Å], forming a supra-molecular metal-organic framework.

Crystal structure of poly[[di-aqua-tetra-μ2-cyanido-iron(II)platinum(II)] acetone disolvate].

Project description:In the title polymeric complex, {[FePt(CN)4(H2O)2]·2C3H6O} n , the FeII cation has an octa-hedral [FeN4O2] geometry being coordinated by two water mol-ecules and four cyanide anions. The Pt cation is located on an inversion centre and has a square-planar coordination environment formed by four cyanide groups. The tetra-cyano-platinate anions bridge the FeII cations to form infinite two-dimensional layers that propagate in the bc plane. Two guest mol-ecules of acetone per FeII are located between the layers. These guest acetone mol-ecules inter-act with the coordinated water mol-ecules by O-H⋯O hydrogen bonds.

Crystal structure of a low-spin poly[di-μ3-cyanido-di-μ2-cyanido-bis-(μ2-2-ethyl-pyrazine)-dicopper(I)iron(II)].

Project description:In the title metal-organic framework, [Fe(C6H8N2)2{Cu(CN)2}2] n , the low-spin FeII ion lies at an inversion centre and displays an elongated octa-hedral [FeN6] coordination environment. The axial positions are occupied by two symmetry-related bridging 2-ethyl-pyrazine ligands, while the equatorial positions are occupied by four N atoms of two pairs of symmetry-related cyanide groups. The CuI centre is coordinated by three cyanide carbon atoms and one N atom of a bridging 2-ethyl-pyrazine mol-ecule, which form a tetra-hedral coordination environment. Two neighbouring Cu atoms have a short Cu⋯Cu contact [2.4662 (7) Å] and their coordination tetra-hedra are connected through a common edge between two C atoms of cyanide groups. Each Cu2(CN)2 unit, formed by two neighbouring Cu atoms bridged by two carbons from a pair of μ-CN groups, is connected to six FeII centres via two bridging 2-ethyl-pyrazine mol-ecules and four cyanide groups, resulting in the formation of a polymeric three-dimensional metal-organic coordination framework.

Crystal structure of catena-poly[[[(2-eth-oxy-pyrazine-?N)copper(I)]-di-?2-cyanido] [copper(I)-?2-cyanido]].

Project description:In the asymmetric unit of the title coordination compound, {[Cu(CN)(C4H3OC2H5N2)][Cu(CN)]} n , there are two Cu atoms with different coordination environments. One CuI ion is coordinated in a triangular coordination geometry by the N atom of the 2-eth-oxy-pyrazine mol-ecule and by two bridging cyanide ligands, equally disordered over two sites exchanging C and N atoms, thus forming polymeric chains parallel to the c axis. The other Cu atom is connected to two bridging cyanide groups disordered over two sites with an occupancy of 0.5 for each C and N atom, and forming an almost linear polymeric chain parallel to the b axis. In the crystal, the two types of chain, which are orthogonal to each other, are connected by cuprophilic Cu?Cu inter-actions [2.7958?(13)?Å], forming two-dimensional metal-organic coordination layers parallel to the bc plane. The coordination framework is further stabilized by weak long-range (electrostatic type) C-H?? inter-actions between cyano groups and 2-eth-oxy-pyrazine rings.

Poly[[diaquadi-?(2)-cyanido-bis-(?(2)-pyrazine-2-carboxyl-ato)dicopper(I)copper(II)] dihydrate].

Project description:In the title compound, {[Cu(II)Cu(I) (2)(C(5)H(3)N(2)O(2))(2)(CN)(2)(H(2)O)(2)]·2H(2)O}(n), the Cu(II) atom lies on an inversion centre and is octa-hedrally coordinated by two N atoms and two O atoms from opposing pyrazine-2-carboxyl-ate (2-pac) ligands and two water O atoms. The Cu(I) atom has a triangular geometry, coordinated by one N atom and one C atom from two bridging cyanide ligands, and another N atom from the 2-pac ligand. The three-dimensional structure features a succession of two-dimensional sheets containing [Cu(CN)](n) chains linked by Cu(2-pac)(2)(H(2)O)(2) groups. The coordinated and free water mol-ecules are involved in an extended three-dimensional hydrogen-bond network with the 2-pac ligands.

?-Pyrazine-bis-[tetra-aqua-cadmium(II)] ?-pyrazine-bis-[tetra-acetato-cadmium(II)].

Project description:In the title dinuclear ionic complex, [Cd(2)(C(4)H(4)N(2))(H(2)O)(8)][Cd(2)(CH(3)CO(2))(8)(C(4)H(4)N(2))], the cation and anion are disordered equally over a site with symmetry mmm. The Cd(II) ions and the N atoms of the bridging pyrazine ligand lie on the inter-section of two crystallographic mirror planes. The C atoms of the bridging pyrazine ligand lie on one of these mirror planes, and the acetate groups and water mol-ecules lie across the inter-secting mirror planes. Each Cd(II) atom in the cation is five-coordinated by four O atoms from four water mol-ecules and one N atom from the bridging pyrazine ligand, whereas each Cd(II) in the anion is nine-coordinated by four pairs of O atoms from the bidentate acetate ligands and one N atom from the bridging pyrazine ligand. In the crystal structure, each anion is surrounded by eight nearest-neighbour cations and vice versa. The crystal structure is stabilized by ionic inter-actions as well as by C-H?O inter-actions.

Crystal structure of high-spin tetra-aqua-bis-(2-chloro-pyrazine-κN (4))iron(II) bis-(4-methyl-benzene-sulfonate).

Project description:The title salt, [Fe(II)(C4H3ClN2)2(H2O)4](C7H7O3S)2, contains a complex cation with point group symmetry 2/m. The high-spin Fe(II) cation is hexa-coordinated by four symmetry-related water and two N-bound 2-chloro-pyrazine mol-ecules in a trans arrangement, forming a distorted FeN2O4 octa-hedron. The three-dimensional supra-molecular structure is supported by inter-molecular O-H⋯O hydrogen bonds between the complex cations and tosyl-ate anions, and additional π-π inter-actions between benzene and pyrazine rings. The methyl H atoms of the tosyl-ate anion are equally disordered over two positions.

Project description:In the title complex, {[Cu(2)Mo(CN)(8)(C(12)H(30)N(6)O(2))(2)]·4H(2)O}(n), the polyhedron around Mo has site symmetry with a distorted square-antiprismatic shape, while the Cu atom (2 symmetry) is in a distorted axially elongated octa-hedral coordination environment. The uncoordinated water molecule is disordered over three sites with occupancies of 0.445 (7), 0.340 (7) and 0.215 (7). Mo and Cu atoms acting as basic components are connected by an Mo-CN-Cu-NC-Mo- linkage to form a distorted diamond-like network. Additional hydrogen bonding between the N-H groups and the water molecules stabilizes this arrangement.

Crystal structure of a two-dimensional grid-type iron(II) coordination polymer: poly[[di-aqua-tetra-?-cyanido-diargentate(I)iron(II)] trans-1,2-bis(pyridin-2-yl)ethyl-ene disolvate].

Project description:In the title compound, {[Ag2Fe(CN)4(H2O)2]·2C12H10N2} n , the asymmetric unit contains one Fe(II) cation, two water mol-ecules, two di-cyanido-argentate(I) anions and two uncoordinating 1,2-bis-(pyridin-2-yl)ethyl-ene (2,2'-bpe) mol-ecules. Each Fe(II) atom is six-coordinated in a nearly regular octa-hedral geometry by four N atoms from di-cyanido-argentate(I) bridges and two coordinating water mol-ecules. The Fe(II) atoms are bridged by di-cyanido-argentate(I) units to give a two-dimensional layer with square-grid spaces. The inter-grid spaces with inter-layer distance of 6.550?(2)?Å are occupied by 2,2'-bpe guest mol-ecules which form O-H?N hydrogen bonds to the host layers. This leads to an extended three-dimensional supra-molecular architecture. The structure of the title compound is compared with some related compounds containing di-cyanido-argentate(I) ligands and N-donor organic co-ligands.

Bis(tetraphenylphosphonium) tetra-cyanido-nitridochromate(V) dihydrate.

Project description:In the title compound, (C(24)H(20)P)(2)[Cr(CN)(4)(N)]·2H(2)O, the complex anion exhibits a square-based pyramidal geometry around the central Cr(V) atom, which is coordinated by a nitride ligand in the apical position and by four cyanide ligands in the equatorial plane. The chromium atom is located 0.4493?(13)?Å out of the plane formed by the ligating C atoms of the cyanide ligands. The water mol-ecules of crystallization form inter-molecular O-H?N hydrogen bonds to the N atoms of two cyanide ligands of neighbouring complex anions, forming an infinite hydrogen-bonded chain parallel to [011] of water mol-ecules and [Cr(N)(CN)(4)](2-) anions. The terminal nitride ligands are not engaged in inter-molecular inter-actions.
