Tetra-kis(di-propyl-ammonium) tetra-kis(oxa-lato-?(2) O (1),O (2))stannate(IV) mono-hydrate: a complex with an eight-coordinate Sn(IV) atom.

ABSTRACT: In the title salt, [(CH3CH2CH2)2NH2]4[Sn(C2O4)4]·H2O, the Sn(IV) atom of the stannate anion is located on a special position with -42m symmetry. It is eight-coordinated by four chelating oxalate anions. The di-propyl-ammonium cation possesses mirror symmetry while the lattice water mol-ecule is disordered about a position with -42m symmetry and has an occupancy of 0.25. In the crystal, the anions and cations are linked by N-H?O hydrogen bonds, forming a three-dimensional network. This network is futher stabilized by weak O-H?O hydrogen bonds involving the water mol-ecules and oxalate O atoms. The crystal studied was refined as an inversion twin.

Disodium tricopper(II) tetra-kis[selenate(IV)] tetra-hydrate.

Project description:The title compound, Na(2)Cu(3)(SeO(3))(4)(H(2)O)(4), has been prepared under hydro-thermal conditions. The crystal structure contains a three-dimensional anionic framework made up from distorted [CuO(4)(H(2)O)(2)] octa-hedra ( symmetry), [CuO(4)(H(2)O)] square pyramids and trigonal-pyramidal SeO(3) units sharing common corners. The connectivity among these units leads to four- and eight-membered polyhedral rings, which by edge-sharing inter-connect into walls. A rhombus-like 16-membered polyhedral ring channel system with a longest length of approximately 14.0 Å and a shortest length of 5.3 Å is enclosed by such walls along the a axis. The water mol-ecules attached to the Cu atoms, as well as the electron lone pairs of the Se(IV) atoms, protrude into these channels. The seven-coordinated Na(+) counter-cations occupy the remaining free space of the 16-membered polyhedral ring channels. An intricate network of O-H⋯O hydrogen bonds further consolidates the three-dimensional structure.

Hexa-kis-(propyl-ammonium) benzene-1,2,4,5-tetra-carboxyl-ate 2,5-dicarb-oxy-benzene-1,4-carboxyl-ate tetra-hydrate.

Project description:The title organic salt, 6C(3)H(10)N(+)·C(10)H(2)O(8) (4-)·C(10)H(4)O(8) (2-)·4H(2)O, contains seven independent entities in the asymmetric unit which comprises three propyl-ammonium cations, two water mol-ecules, half a 2,5-dicarb-oxy-benzene-1,4-carboxyl-ate dianion (H(2)btc(2-)) and half a benzene-1,2,4,5-tetra-carboxyl-ate tetra-anion (btc(4-)), the latter two anions being located about centres of inversion. One of the water mol-ecules is disordered over two positions in a 0.55 (2):0.45 (2) ratio. The combination of mol-ecular ions and water mol-ecules results in an extensive and complex three-dimensional network of hydrogen bonds, the network being made up of nine unique N-H⋯O inter-actions between the ammonium cations and the anions, as well as four unique O-H⋯O inter-actions between the water mol-ecules and the anions.

Tetra-butyl-ammonium butyl-tetra-chlorido-stannate(IV).

Project description:In the title compound, [N(C4H9)4][Sn(C4H9)Cl4], the Sn(IV) atom of the stannate anion has a trigonal-bipyramidal coordination sphere by two Cl atoms and one butyl chain in the equatorial plane and by two Cl atoms in the apical positions. Two of the four butyl chains of the tetra-butyl-ammonium cation are partially disordered, each with refined site occupancies of 0.691?(6):0.309?(6). Weak C-H?Cl hydrogen-bonding inter-actions help to consolidate the crystal packing, as well as a short Cl?Cl inter-action of 3.295?(2)?Å.

cyclo-Tetra-kis(?-naphthalene-1,8-dicarboxyl-ato)tetra-kis-[diaqua-(2,2'-bipyridine)-manganese(II)] tetra-hydrate.

Project description:In the title centrosymmetric tetra-nuclear complex, [Mn(4)(C(12)H(6)O(4))(4)(C(10)H(8)N(2))(4)(H(2)O)(8)]·4H(2)O, two independent Mn(II) ions are coordinated in a slightly disorted octa-hedral environment by two aqua ligands, two naphthalene-1,8-dicarboxyl-ate (1,8-nap) ligands and one bis-chelating 2,2'-bipyridine (2,2'-bipy) ligand. In the crystal, mol-ecules are linked by inter-molecular O-H?O hydrogen bonds into chains along [100]. These chains are further linked by weak ?-? inter-actions with centroid-centroid distances in the range of 3.609?(2)-3.758?(1)?Å, forming a three-dimensional supra-molecular network.

In the crystal, the components are linked by inter-molecular N-H?O hydrogen bonds, forming a one-dimensional network along [100].

5,10,15,20-Tetra-kis(1-methyl-pyridinium-4-yl)porphyrin tetra-iodide tetra-hydrate.

Project description:The asymmetric unit of the title compound, C(44)H(38)N(8) (2+)·4I(-)·4H(2)O, comprises two halves of non-equivalent cations of 5,10,15,20-tetra-kis-(1-methyl-pyridinium)porphyrin (with the full mol-ecule of each completed by the application of inversion symmetry), four charge balancing iodide anions and four water mol-ecules of crystallization (two water mol-ecules are fully occupied and four mol-ecules have a site occupancy of 50%). The porphyrin cations are arranged into supramolecular columns parallel to the b axis, mediated by π-π [centroid-centroid distance = 3.762 (4) Å] and C-H⋯π supra-molecular inter-actions [C⋯centroid distance = 3.522 (7) Å, C-H⋯centroid = 128°], leading to the formation of columns parallel to the b axis. The close packing leads to the presence of a one-dimensional channel filled with partially occupied water mol-ecules engaged in O-H⋯O and O-H⋯I hydrogen bonds.

Bis(cyclo-hexyl-ammonium) tetra-chlorido-diphenyl-stannate(IV).

Project description:The title compound, (C6H14N)2[Sn(C6H5)2Cl4], contains cyclo-hexyl-ammonium cations in general positions and a stannate(IV) anion that is located on a twofold rotation axis. The Sn(IV) atom in the complex anion is surrounded by four Cl(-) ligands and two trans-phenyl groups in a distorted octa-hedral configuration. The anions are connected with the cations through N-H?Cl hydrogen bonds. Every cation is involved in three N-H?Cl bonds to the chloride ligands of three different anions, and each chloride ligand is linked to two cations. This arrangement leads to a layered structure parallel to (010).

Bis(cyclo-hexyl-ammonium) tetra-chlorido-(oxalato)stannate(IV).

Project description:The title salt, (C6H14N)2[Sn(C2O4)Cl4], was obtained as a by-product from the reaction between 2C6H14N(+)·C2O4 (2-)·1.5H2O and SnCl2·2H2O. The cyclo-hexyl-ammonium cation has a chair conformation. The complex anion consists of an oxalate anion chelating the SnCl4 moiety, resulting in a distorted octa-hedral coordination sphere of the Sn(IV) atom with the O atoms in equatorial cis positions. In the crystal, cations and anions are linked through N-H?O and N-H?Cl inter-actions into a layered arrangement parallel to (100).
