The one-dimensional organic inorganic hybrid compound poly[(diethyl-ene-triamine)tetra-?-iodido-dilead(II)].

ABSTRACT: A new organic-inorganic hybrid, [Pb(2)I(4)(C(4)H(13)N(3))](n), was obtained by the reaction of C(4)N(3)H(10) and PbI(2) at room temperature. The structure is a three-dimensional polymer resulting from the association of PbI(6) octa-hedra and a mixed lead organic-inorganic PbI(4)(C(4)N(3)H(13)) coordination polyhedron. Both Pb atoms, two I atoms and one N atom lie on a mirror plane. N-H?I hydrogen bonds further connect the organic unit and some I atoms.

Crystal structures of isotypic poly[bis-(benz-imid-azolium) [tetra-μ-iodido-stannate(II)]] and poly[bis-(5,6-di-fluoro-benzimidazolium) [tetra-μ-iodido-stannate(II)]].

Project description:The isostructural title compounds, {(C7H7N2)2[SnI4]} n , (1), and {(C7H5F2N2)2[SnI4]} n , (2), show a layered perovskite-type structure composed of anionic {[SnI4](2-)} n sheets parallel to (100), which are decorated on both sides with templating benzimidazolium or 5,6-di-fluoro-benzimidazolium cations, respectively. These planar organic heterocycles mainly form N-H⋯I hydrogen bonds to the terminal I atoms of the corner-sharing [SnI6] octa-hedra (point group symmetry 2) from the inorganic layer, but not to the bridging ones. This is in contrast to most of the reported structures of related compounds where ammonium cations are involved. Here hydrogen bonding to both types of iodine atoms and thereby a distortion of the inorganic layers to various extents is observed. For (1) and (2), all Sn-I-Sn angles are linear and no out-of-plane distortions of the inorganic layers occur, a fact of relevance in view of the material properties. The arrangement of the aromatic cations is mainly determined through the direction of the N-H⋯I hydrogen bonds. The coherence between organic bilayers along [100] is mainly achieved through van der Waals inter-actions.

(?(4)-Cyclo-octa-tetra-ene)(?(8)-cyclo-octa-tetra-ene)iodido-tantalum(V).

Project description:The title complex, [Ta(?(4)-C8H8)(?(8)-C8H8)I], lies across a crystallographic mirror plane that includes the Ta(V) atom and the iodide ligand. One cyclo-octa-tetra-ene (cot) ring is ?(4)-coordinating and is bis-ected by the mirror plane. The fold angle between the plane of the coordinating butadiene portion and the middle plane of the ring is 27.4?(4)°. An additional minor fold angle of 9.3?(7)° exists between the final plane in the ring and the middle plane. The other cot?ring is ?(8)-coordinating and is also cut by the mirror plane. In this case, the ring is disordered over the mirror plane, and one position is modeled with appropriate restraints and constraints with respect to distances, angles and displacement parameters (the second position is generated by symmetry). This ring is nearly planar, with an r.m.s. deviation of only 0.05?Å when all eight C atoms are included in the calculation. Pairs of inter-molecular ?(8)-cot?rings are parallel stacked and slightly off center, with a centroid-centroid distance of 3.652?Å. No other significant inter-molecular inter-actions are observed. The compound is of inter-est as the first structurally characterized mixed halogen-cot?complex of the group 5 metals and contains the longest terminal Ta-I distance [3.0107?(5)?Å] reported to date.

Project description:The reaction of CdCl(2), 18-crown-6 and KI in water yields the title coordination polymer, [{K(C(12)H(24)O(6))}(2)Cd(2)I(6)](n). The potassium ion lies approximately in the plane of the crown ether, coordinated by all six crown ether O atoms and also by an iodide anion bound to a cadmium atom. A C atom of the crown ether is disordered over two positions with site occupancies of 0.77 (2) and 0.23 (2). Two K(18-crown-6)(+) units are linked by inversion symmetry, forming a [bis-(μ(2)-18-crown-6)dipottasium] system with approximately square-planar K(2)O(2) units. Inversion symmetry also generates the Cd(2)I(6) fragment and the polymeric system is extended along the c axis by the formation of K-I-Cd bridges.

catena-Poly[[cadmium-bis-(μ-triethyl-ene-tetra-mine-κN,N':N'',N''')-cadmium-(μ-triethyl-ene-tetra-mine-κN,N':N'',N''')] hexa-fluoridogermanate].

Project description:The title fluoridogermanate, {[Cd(2)(C(6)H(18)N(4))(3)][GeF(6)]}(n), was synthesized hydro-thermally. The crystal structure comprises undulated cationic [Cd(2)(TETA)(3)](4+) chains (TETA is triethyl-ene-tetra-mine) propagating parallel to [101]. The central Cd(II) atom is six-coordinated in a CdN(6) set by three TETA ligands. The isolated [GeF(6)](2-) units, serving as counter-anions, occupy the inter-chain spaces and simultaneously link adjacent chains into a three-dimensional network through extensive N-H⋯F hydrogen-bonding inter-actions. One of the ethyl-ene bridges of one TETA ligand is disordered around a twofold rotation axis.

catena-Poly[[trans-bis-(cyclo-hexane-1,2-diamine-κ²N,N)cadmium]-μ-iodido-(diiodidocadmium)-μ-iodido].

Project description:In the title compound, [Cd₂I₄(C₆H₁₄N₂)₂](n), there are two independent Cd(II) ions. One Cd(II) ion is coordinated in a slightly distorted octa-hedral coordination environment by four N atoms from two cyclo-hexane-1,2-diamine ligands and two iodido ligands. The other Cd(II) ion is coordinated by four iodido ligands in a slightly distorted tetra-hedral coordination environment. Two of the iodido ligands act as bridging ligands connecting Cd(II) ions and forming a one-dimensional polymer along [010]. In the crystal, N-H⋯I hydrogen bonds connect the one-dimensional structure into a two-dimensional framework parallel to (001).

Redetermination of the crystal structure of catena-poly[[[bis-(ethyl-enedi-amine)-platinum(II)]-μ-iodido-[bis-(ethyl-enedi-amine)-platinum(IV)]-μ-iodido] tetra-kis-(octane-1-sulfonate) dihydrate].

Project description:The structure of the title compound, which represents a mixed-valence platinum(II,IV) complex, {[Pt(II)Pt(IV)I2(C2H8N2)4][CH3(CH2)7SO3]4·2H2O} n , has been redetermined in a different space group. In contrast to the previously reported determination in the space group P21 cn [Matsushita & Taira (1999 ▸). Synth. Met. 102, 1787-1788], the current model was refined in the centrosymmetric space group Pmcn using the original diffraction data. The title compound has a linear chain structure composed of square-planar [Pt(en)2](2+) and elongated octa-hedral trans-[PtI2(en)2](2+) cations (en is ethyl-enedi-amine) stacked alternately, bridged by the I atoms, parallel to the c axis. Inorganic layers aligned parallel to the bc plane, composed of the Pt-complex columns, the -SO3 (-) part of the octane-1-sulfonate anion, and the water mol-ecule of crystallization, are stacked alternately with organic layers composed of the long-chain alkyl groups along the a axis. The Pt and I sites are located on the same mirror plane whereby the I site is equally disordered over two positions. The Pt and I atoms form a slight zigzag ⋯I-Pt(IV)-I⋯Pt(II)⋯ chain, with Pt(IV)-I bond lengths of 2.6888 (17) and 2.7239 (17) Å, Pt(II)⋯I contacts of 3.2065 (17) and 3.1732 (16) Å, and Pt(IV)-I⋯Pt(II) angles of 178.3 (3) and 176.7 (2)°. The mixed-valence state of the Pt site is expressed by the structural parameter δ = (Pt(IV)-I)/(Pt(II)⋯I), with values of 0.839 and 0.858 for the two independent I atoms. In the crystal, N-H⋯O hydrogen bonds involving the cationic chains, the sulfonate groups and water mol-ecules of crystallization, stabilize the columnar structure.

catena-Poly[1,1'-dimethyl-4,4'-(ethane-1,2-di-yl)dipyridinium [lead(II)-tri-μ-iodido-lead(II)-tri-μ-iodido]].

Project description:The title compound, {(C(14)H(18)N(2))[Pb(2)I(6)]}(n), consists of discrete 1,1'-dimethyl-4,4'-(ethane-1,2-di-yl)dipyridinium cations and one-dimensional [Pb(2)I(6)](n) anions. The organic cation has an inversion center at the mid-point of the ethane C-C bond. In the anion, the Pb(II) atom is coordinated by six I atoms in a distorted octa-hedral geometry. The I atoms bridge the Pb(II) atoms into a polymeric chain running along [001]. These inorganic chains are separated by the isolated organic cations.
