Tetra-ammonium bis-(metforminium) di-μ₆-oxido-tetra-μ₃-oxido-tetra-deca-μ₂-oxido-octa-oxidodeca-vanadium(V) hexa-hydrate.

ABSTRACT: The title compound, (NH₄)₄(C₄H₁₂N₅)₂[V₁₀O₂₈]·6H₂O, crystallizes with the deca-vanadate anion placed on an inversion centre in space group P . This anion is surrounded by a first shell of ammonium cations and water mol-ecules, forming efficient N-H⋯O and O-H⋯O hydrogen bonds. A second shell includes metforminium monocations with a twisted geometry, also forming numerous inter-molecular hydrogen bonds. The complex three-dimensional network of non-covalent inter-actions affords a crystal structure in which the cations and anions are densely packed.

Crystal structure of tetrakis-(acetyl-acetonato)di-chloridodi-μ3-methano-lato-tetra-μ2-methano-lato-tetra-iron(III).

Project description:The title complex, [Fe4(C5H7O2)4(CH3O)6Cl2] or [Fe4(acac)4(μ2-OMe)4(μ3-OMe)2Cl2] (acac = acetyl-acetonate), crystallizes in the ortho-rhom-bic Pbca space group with one half of the mol-ecule per asymmetric unit, the other half being completed by inversion symmetry. The core structure consists of a face-sharing double pseudo-cubane entity with two opposite corners missing. Weak C-H⋯Cl inter-molecular inter-actions result in a two-dimensional layered structure parallel to the ac plane.

Tris[N,N-bis(3,5-di-tert-butylbenzyl)dithiocarbamato-κ2S,S′]-μ3-sulfido-tris-μ2-disulfido-triangulo-trimolybdenum(IV) iodide

Project description:[Mo3S7(S2CN(CH2C6H3-3,5-tBu2)2)3]+⋯I− crystallizes upon a threefold symmetry axis in P31c with the packing arrangement enforced by dispersion forces between the hydrocarbon-rich peripheral CH2C6H3-3,5-tBu2 groups. The title compound, [Mo3(C31H46NS2)3S7]I, crystallizes on a threefold rotational axis in P31c (space group No. 159). The [Mo3S7(S2CN(CH2C6H3-3,5-tBu2)2)3]+ cations are arrayed in sheets in the ab plane with interligand hydrophobic interactions between tert-butyl groups guiding the packing arrangement. These cations form stacks parallel to the c axis with a separating distance of 10.9815 (6) Å (the c axis length) between the Mo3 centroids. On the underside of the cluster, opposite the μ3-S2− ligand, the iodide counteranion forms close contacts of 3.166 (2) Å with the sulfur atoms of the μ2-S22− ligands. These contacts are less than the sum of the van der Waals radii of the atoms (1.8 and 2.1 Å for S and I, respectively), thus indicating an appreciable degree of covalency to the [Mo3S7(S2CN(CH2C6H3-3,5-tBu2)2)3]+⋯I− interactions.

Bis(4-amino-pyridinium) μ6-oxido-dodeca-μ2-oxido-hexaoxido[rhenium(VII)tetratungsten(VI)vanadium(V)]ate hepta-hydrate.

Project description:In the title organic-inorganic hybrid compound, (C5H7N2)2[ReVW4O19]·7H2O, the Lindqvist-type polyoxido anion has crystallographically imposed mm2 symmetry and is built up by six MO6 (M = W, V, Re) edge-sharing distorted octa-hedra. The Re and V atoms share the same crystallographic site in a 0.5:0.5 ratio. The 4-amino-pyridinium cations lie on a mirror plane. Three of the four independent water O atoms in the asymmetric unit are located on a mirror plane whereas the remaining O atom has mm2 site symmetry. In the crystal, the cations, anions and water mol-ecules are linked into a three-dimensional network through O-H⋯O and N-H⋯O hydrogen-bonding inter-actions.

Project description:The tetra-nuclear title compound, [Sn4(CH3)8(C2H5O)2O2(C3H4N3S)2], lies about a center of inversion; the mol-ecule features a three-rung-staircase Sn4O4 core in which two Sn(IV) atoms are bridged by the 4-methyl-5-sulfanyl-idene-4,5-dihydro-1H-1,2,4-triazol-1-ide group.

The terminal Sn(IV) atom is five-coordinate in a cis-C2SnNO2 trigonal-bipyramidal geometry [C-Sn-C = 127.5 (2)°], whereas the central Sn(IV) atom is six-coordinate in a C2SnNO3 skew-trazepoidal bipyramidal geometry [C-Sn-C = 145.0 (2)°].

Hexa-μ2-acetato-hexa-n-butyl-hexa-μ3-oxido-tin(IV) toluene monosolvate.

Project description:The title compound, [Sn6(C4H9)6(CH3COO)6O6]·C7H8, has one half-toluene mol-ecule and one half-organotin mol-ecule in the asymmetric unit. The latter is situated about an inversion centre and belongs to the class of hexa-meric monoorganooxo-tin carboxyl-ates with a hexa-gonal prismatic or 'drum-like' motif of the central tin-oxygen core. Two Sn3O3 rings in a flat-chair conformation are linked via six Sn-O bonds and six bridging acetate groups. All Sn atoms have approximate octa-hedral coordination geometry. The Sn-O bonds which are trans to the alkyl group are significantly shorter than the others. One butyl group is disordered over two different sites, with occupancies of 0.9:0.1. Very large atomic displacement parameters of the toluene mol-ecule indicate an unresolvable disorder about the twofold axis.

Crystal structure of poly[μ6-adipato-di-aquadi-μ2-oxalato-didysprosium(III)].

Project description:In the title coordination polymer, [Dy2(C6H8O4)(C2O4)2(H2O)2] n , the asymmetric unit consists of one Dy(3+) cation, one half of an adipate anion, two halves of oxalate anions and one coordinating water mol-ecule. The adipate and oxalate ions are located on centres of inversion. The Dy(3+) cation has a distorted tricapped trigonal-prismatic geometry and is coordinated by nine O atoms, four belonging to three adipate anions, four to two oxalate anions and one from an aqua ligand. The cations are bridged by adipate ligands, generating a two-dimensional network parallel to (010). This network is further extended into three dimensions by coordination of the rigid oxalate ligands and is further consolidated by O-H⋯O hydrogen bonds. A part of the adipate anion is disordered over two positions in a 0.75:0.25 ratio.

Crystal structure of octa-kis-(N,N-di-methyl-formamide-κO)europium(III) tetra-cosa-μ2-oxido-dodeca-oxido-μ12-phosphato-dodeca-molybdate(VI).

Project description:In the title salt, [Eu(C3H7NO)8][PMo12O40], the asymmetric unit comprises one α-Keggin-type [PMo12O40](3-) polyoxidometalate anion and one distorted dodeca-hedral [Eu(C3H7NO)8](3+) complex cation. In the crystal, the isolated polyoxidometalate anions are packed into hexa-gonally arranged rows extending parallel to [001]. The complex cations are situated between the rows and are linked to the neighbouring anions through weak C-H⋯O hydrogen-bonding inter-actions, leading to the formation of a three-dimensional network structure.
