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

ABSTRACT: 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.

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.

Octa-aqua-bis(μ(2)-1H-pyrazole-3,5-di-carboxyl-ato)tricopper(II) tetra-hydrate.

Project description:In the trinucler Cu(II) complex mol-ecule of the title compound, [Cu(3)(C(5)HN(2)O(4))(2)(H(2)O)(8)]·4H(2)O, the central Cu(II) atom is located on an inversion centre and is coordinated in a distorted octa-hedral geometry. The equatorial sites are occupied by two N and two O atoms from two pyrazole-3,5-dicarboxyl-ate ligands and the axial positions are occupied by two water mol-ecules. The two other symmetry-related Cu(II) atoms are penta-coordinated and assume a square-pyramidal geometry. In the crystal structure, coordinated and uncoordinated water mol-ecules and carboxyl-ate O atoms are linked by O-H⋯O hydrogen bonds.

Calcium disodium hexa-thio-diphosphate(IV) octa-hydrate.

Project description:Single crystals of the title compound, CaNa(2)(P(2)S(6))·8H(2)O, were obtained by adding calcium hydroxide to an aqueous solution of Na(4)(P(2)S(6))·6H(2)O. The structure is isotypic with that of its strontium analogue and consists of one Ca(2+) cation, two Na(+) cations, one-half of a centrosymmetric (P(2)S(6))(4-) anion with staggered confirmation and four water mol-ecules in the asymmetric unit. The crystal structure can be described as being built up from layers of cations and anions extending parallel to (101). Within a layer, each CaO(8) polyhedron is connected via edge-sharing to two NaO(4)S(2) octa-hedra and to one NaO(2)S(4) octa-edron. The NaO(4)S(2) octa-hedra are, in turn, linked with two (P(2)S(6))(4-) anions through common corners. Various O-H?S hydrogen-bonding inter-actions lead to cohesion of adjacent layers. The Ca(2+) and one Na(+) cation are situated on a twofold rotation axis and the second Na(+) cation is situated on an inversion centre.

Poly[[tetra-aqua-tetra-kis-[?3-5-(pyridine-4-carboxamido)-isophthalato]nickel(II)diterbium(III)] tetra-hydrate].

Project description:In the title compound, {[NiTb2(C14H8N2O5)4(H2O)4]·4H2O} n , the Tb(III) ion is coordinated by one water mol-ecule and seven O atoms from four 5-(pyridine-4-carboxamido)-isophthalate (L) ligands in a distorted square-anti-prismatic arrangement, while the Ni(II) ion, lying on an inversion center, is six-coordinated in an octa-hedral geometry by two pyridine N atoms, two carboxyl-ate O atoms and two water mol-ecules. One L ligand bridges two Tb(III) ions and one Ni(II) ion through two carboxyl-ate groups and one pyridine N atom. The other L ligand bridges two Tb(III) ions and one Ni(II) ion through two carboxyl-ate groups, while the uncoordinating pyridine N atom is hydrogen bonded to an adjacent coordinating water mol-ecule. Extensive O-H?O, N-H?O and O-H?N hydrogen bonds play an important role in stabilizing the crystal structure.

Disodium zinc bis-(sulfate) tetra-hydrate (zinc astrakanite) revisited.

Project description:We present a new low-temperature refinement of disodium zinc bis-(sulfate) tetra-hydrate {systematic name: poly[tetra-μ-aqua-di-μ-sulfato-zinc(II)disodium(I)]}, [Na(2)Zn(SO(4))(2)(H(2)O)(4)](n) or Zn astrakanite, which is an upgrade of previously reported data [Bukin & Nozik (1974 ▶). Zh. Strukt. Khim.15, 712-716]. The compound is part of an isostructural family containing the Mg (the original astrakanite mineral), Co and Ni species. The very regular ZnO(aqua)(4)O(sulfate)(2) octa-hedra lie on centres of symmetry, while the rather distorted NaO(aqua)(2)O(sulfate)(4) octa-hedra appear at general positions, linked into a three-dimensional network by the bridging water mol-ecules and the fully coordinated sulfate groups.

(μ-2,2',2'',2'''-{[Pyrazine-2,3,5,6-tetra-yltetra-kis(methyl-ene)]tetra-kis(sulfanedi-yl)}tetra-acetato)bis-[aqua-nickel(II)] hepta-hydrate.

Project description:Reaction of the ligand 2,2',2'',2'''-{[pyrazine-2,3,5,6-tetra-yltetra-kis-(methyl-ene)]tetra-kis-(sulfanedi-yl)}tetra-acetic acid (H4L1), with NiCl2 leads to the formation of a binuclear complex, (μ-2,2',2'',2'''-{[pyrazine-2,3,5,6-tetra-yltetra-kis-(methyl-ene)]tetra-kis-(sulfanedi-yl)}tetra-acetato-κ5 O,S,N 1,S',O':κ5 O'',S'',N 4,S''',O''')bis[aqua-nickel(II)] hepta-hydrate, {[Ni2(C16H16N2O8S4)(H2O)2]·7H2O} (I). It crystallizes with two half mol-ecules in the asymmetric unit. The complete mol-ecules are generated by inversion symmetry, with the center of the pyrazine rings being located at crystallographic centres of inversion. The ligand coordinates two NiII ions in a bis-penta-dentate manner and the sixfold coordination sphere of each nickel(II) atom (NiS2O3N) is completed by a water mol-ecule. The complex crystallized as a hepta-hydrate. The binuclear complexes are linked by Owater-H⋯Ocarbon-yl hydrogen bonds, forming layers parallel to the (101) plane. This layered structure is additionally stabilized by weak C-H⋯O hydrogen bonds. Further O-H⋯O hydrogen bonds involving binuclear complexes and solvent water mol-ecules, together with weak C-H⋯S hydrogen bonds, link the layers to form a supra-molecular framework.

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

Project description: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.

Di-?(4)-succinato-tetra-kis[aqua-phenanthrolinecopper(II)] tetra-nitrate tetra-hydrate.

Project description:In the title compound, [Cu(4)(C(4)H(4)O(4))(2)(C(12)H(8)N(2))(4)(H(2)O)(4)](NO(3))(4)·4H(2)O, the complete tetra-cation is generated by crystallographic inversion symmetry. Both unique Cu(2+) ions are coordinated by an N,N'-bidentate phenanthroline mol-ecule, two O-monodentate bis-bridging succinate dianions and a water mol-ecule, resulting in distorted CuN(2)O(3) square-based pyramidal geometries for the metal ions, with the water mol-ecule occupying the apical site. In the crystal, the components are linked by O-H?O hydrogen bonds and aromatic ?-? stacking inter-actions [minimum centroid-centroid separation = 3.537?(2)?Å].
