Bis[2,2'-(2-amino-ethyl-imino)-di(ethyl-ammonium)] di-μ-sulfido-bis[disulfido-stannate(IV)].

ABSTRACT: The asymmetric unit of the title compound, (C(6)H(20)N(4))(2)[Sn(2)S(6)], comprises half of a [Sn(2)S(6)](4-) anion and a diprotonated tris-(2-amino-eth-yl)amine cation. The anion lies on an inversion center, while the atoms of the cation occupy general positions. An intra-molecular N-H⋯N hydrogen bond is observed in the cation. In the crystal, strong N-H⋯S hydrogen bonding between the terminal sulfur atoms of the anion and the protonated amine N atoms of the cations result in a three-dimensional network.

catena-Poly[[tetra-kis-(hexa-methyl-phospho-ramide-κO)bis-(nitrato-κO,O')yttrium(III)] [silver(I)-di-μ-sulfido-molybdenum(VI)-di-μ-sulfido]].

Project description:In the cation of the title compound, {[Y(NO(3))(2)(C(6)H(18)N(3)OP)(4)][AgMoS(4)]}(n), the Y atom is coordinated by eight O atoms from two chelating nitrate groups and four hexa-methyl-phospho-ramide (hmp) ligands, which gives rise to a distorted square-anti-prismatic environment. Together with the two nitrate ligands, the overall charge for the complex cation is +1, which leads to the anionic chain having a monovalent repeat unit. The polymeric anionic chain, with Mo-Ag-Mo and Ag-Mo-Ag angles of 161.916 (13) and 153.915 (13)°, respectively, presents a distorted linear configuration. The cations and the anions are linked via weak C-H⋯S hydrogen-bonding inter-actions while the cations exhibit inter-molecular C-H⋯O inter-actions. The structure is isotypic with the corresponding W, Yb, Eu, Nd, La and Dy complexes.

catena-Poly[[tetra-kis-(hexa-methyl-phospho-ramide-κO)bis-(nitrato-κO,O')dysprosium(III)] [silver(I)-di-μ-sulfido-tungstate(VI)-di-μ-sulfido]].

Project description:Hexa-methyl-phospho-ramide (hmp), tetra-thio-tungstate, silver sulfide and dysprosium nitrate were self-assembled, forming an anionic [AgWS(4)](n) (n) (-) chain in the title compound, {[Dy(NO(3))(2)(C(6)H(18)N(3)OP)(4)][AgWS(4)]}(n). The central Dy atom in the cation is coordinated by eight O atoms from two didentate nitrate and four hmp ligands, giving rise to a distorted square anti-prismatic structure. Together with the two nitrate ligands, the cation is univalent, which leads to the anionic chain having a [WS(4)Ag] repeat unit. The polymeric anionic chain, with W-Ag-W and Ag-W-Ag angles 161.16 (2) and 153.606 (11)°, respectively, presents a distorted linear configuration. The title compound is isotypic with other rare earth complexes.

Poly[bis(phenethyl-ammonium) [di-bromido-plumbate(II)]-di-μ-bromido]].

Project description:Crystals of the title compound, {(C(6)H(5)C(2)H(4)NH(3))(2)[PbBr(4)]}(n), were grown at room temperature from a solution in N,N-dimethyl-formamide (DMF) using nitro-methane as the poor solvent. This perovskite-type organic-inorganic hybrid compound consists of well ordered sheets of corner-sharing disordered PbBr(6) octa-hedra separated by bilayers of phenethyl-ammonium cations. The octa-hedra are rotated and tilted due to N-H⋯Br hydrogen bonds with the ammonium groups, generating a superstructure in the unit cell similar to that of the tetra-chloridoplumbate (C(6)H(5)C(2)H(4)NH(3))(2)[PbCl(4)].

Di-μ-thio-cyanato-bis-({2,4-dichloro-6-[2-(diethyl-amino)ethyl-imino-meth-yl]phenolato}copper(II)).

Project description:The title compound, [Cu(2)(NCS)(2)(C(13)H(17)Cl(2)N(2)O)(2)], was obtained by the reaction of 3,5-dichloro-salicylaldehyde, N,N-diethyl-ethane-1,2-diamine, sodium thio-cyanate, and copper(II) acetate in an ethanol solution. It crystallizes as a centrosymmetric dimer with a very long Cu⋯S axial bond [2.972 (3) Å]. The Cu atom is five-coordinated by the three donor atoms of the Schiff base ligand, 2,4-dichloro-6-[(2-diethyl-amino-ethyl-imino)meth-yl]phenol, one N atom of a thio-cyanate group, and one S atom of a symmetry-related thio-cyanate group, forming a slightly distorted square-pyramidal geometry.

Di-μ-nitrato-bis-(μ-octa-ethyl pyro-phospho-ramide)-bis-[aqua-dinitratocalcium(II)].

Project description:The title compound, di-μ-nitrato-κ3 O,O':O;O:O,O'-bis-(μ-octa-ethyl pyro-phos-pho-ramide-κ2 O:O')bis-[aqua-bis-(nitrato-κ2 O,O')calcium(II)], [Ca2(NO3)4(C16H40N4O3P2)2(H2O)2] was obtained as a side product during the work up of the synthesis of octa-ethyl pyro-phospho-ramide and represents the first structurally characterized complex of this ligand. The compound crystallizes in the monoclinic space group P21/n and the asymmetric unit contains one pyro-phospho-ramide mol-ecule and one Ca2+ ion coordinated to two nitrate ions and one water mol-ecule. The complex exists as a dimer with a centre of inversion located between two eight-coordinate calcium(II) centres, which are bridged by two nitrate ions and two octa-ethyl pyro-phospho-ramide ligands. Each Ca2+ cation is also coordinated to a further nitrate anion, acting as a bidentate ligand, and a water mol-ecule. The complexes stack parallel to the a axis and are held in place by a network of inter-molecular O-H⋯O hydrogen bonds also running parallel to a.

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.
