Diaqua-tetra-bromidotin(IV) trihydrate.

ABSTRACT: The title compound, [SnBr(4)(H(2)O)(2)]·3H(2)O, forms large colourless crystals in originally sealed samples of tin tetra-bromide. It constitutes the first structurally characterized hydrate of SnBr(4) and is isostructural with the corresponding -hydrate of SnCl(4). It is composed of Sn(IV) atoms octa-hedrally coordinated by four Br atoms and two cis-related water mol-ecules. The octa-hedra exhibit site symmetry 2. They are arranged into columns along [001] via medium-strong O-H⋯O hydrogen bonds involving the two lattice water mol-ecules (one situated on a twofold rotation axis) while the chains are inter-connected via longer O-H⋯Br hydrogen bonds, forming a three-dimensional network.

Poly[[piperazine-1,4-dium [diaqua-tetra-kis-(μ-sulfanediyldiacetato)-dicerate(III)]] trihydrate].

Project description:The title compound, (C(4)H(12)N(2))[Ce(2)(C(4)H(4)O(4)S)(4)(H(2)O)(2)]·3H(2)O, features a polymeric anion with a centrosymmetric Ce(2)O(2) core and a Ce⋯Ce distance of 4.3625 (4) Å. The anions form ribbons {[Ce(2)(C(4)H(4)O(4)S)(4)(H(2)O)(2)](2-)}(n) extending along [100]. The doubly protonated piperazinium cations reside on centers of inversion and link the polymeric ribbons via N-H⋯O hydrogen bonding. Each Ce(III) cation is ten-coordinated by an O(2)S donor set from two tridentate sulfanediyldiacetate (tda) ligands, one water mol-ecule and three other tda O donors from adjacent {Ce(tda)(2)(H(2)O)} units in a distorted bicapped cubic environment. Additional O-H⋯O hydrogen bonding involving the coordinated and solvent water mol-ecules is also present. H atoms of the crystal water molecules could not be located and were not included in the refinement.

Tetra-ethyl-ammonium bicarbonate trihydrate.

Project description:In the title compound, C(8)H(20)N(+)·CHO(3) (-)·3H(2)O, the bicarbon-ate anion, which has a small mean deviation from the plane of 0.0014 Å, fully utilises its three O and one H atom to form various O-H⋯O hydrogen bonds with the three water mol-ecules in the asymmetric unit, generating a hydrogen-bonded layer, which extends along (10[Formula: see text]). The tetra-ethyl-ammonium cations, as the guest species, are accommodated between every two neighboring layers, constructing a sandwich-like structure with an inter-layer distance of 7.28 Å.

Project description:The title compound {[Cu(2)Ho(2)(C(4)H(5)O(2))(10)(H(2)O)(4)]·3H(2)O}(n), is a one-dimensional 3d/4f organic-inorganic hybrid complex, the Ho(III) member of the isotypic lanthanoid series with Ln = Gd(III), Er(III) and Y(III). The structure shows an alternation of Cu(2) and Ho(2) dinuclear units bridged by the ligands and hydrogen bonds only. The chains are composed of Cu(2) classical dinuclear η(1):η(1):μ(2) fourfold bridges [Cu⋯Cu = 2.6417 (9) Å] and of Ho(2) units bridged by two η(2):η(1):μ(2) carboxyl-ate units. This results in distorted square-based pyramidal CuO(5) units and irregular HoO(9) units. The alternating Cu(2) and Ho(2) units are bridged into linear arrays along the a axis by a set of one η(2):η(1):μ(2) carboxyl-ate O atom and two hydrogen bonds with Cu⋯Ho separations of 4.4883 (10) and 4.5086 (10) Å. The distance between adjacent chains, as calculated by the closest and furthest distances between two chains, covers the range 10-14 Å. The H atoms of the water mol-ecules could not be located, but the O⋯O separations for these species suggest the presence of O-H⋯O hydrogen bonds.

Project description:The title compound (NH(4))(4)[Mo(8)O(24)(O(2))(2)(H(2)O)(2)]·4H(2)O, consists of an octa-molybdate cluster with a crystallographic centre of symmetry.

Hydrogen bonding also exists between the coordinated water mol-ecules of one cluster with one of the O atoms of the peroxido fragment in a neighbouring cluster.

Disodium dihydrogen pyridine-2,3,5,6-tetra-carboxyl-ate trihydrate.

Project description:In the title compound, 2Na(+)·C(9)H(3)NO(8) (2-)·3H(2)O, the asymmetric unit consists of two Na(+) cations, one dihydrogen pyridine-2,3,5,6-tetra-carboxyl-ate dianion (H(2)pdtc(2-)) and three water mol-ecules coordinated to the Na(+) cations. The configuration of the anion is stabilized by intramolecular O-H⋯O hydrogen bonding between vicinal carboxylate/carboxy groups. The Na(+) cations are bridged by the H(2)pdtc(2-) dianions, generating layers extending infinitely in sheets parallel to (001), and further pillared by the water mol-ecule linkers to build up a three-dimensional framework.

Diaqua-(1,4,8,11-tetra-aza-cyclo-tetra-deca-ne)nickel(II) fumarate tetra-hydrate.

Project description:The asymmetric unit of the title complex salt, [Ni(C(10)H(24)N(4))(H(2)O)(2)](C(4)H(2)O(4))·4H(2)O, comprises half of a nickel(II) complex dication, half of a fumarate dianion and two water mol-ecules. Both the Ni(II) cation and fumarate anion lie on a crystallographic inversion center. The Ni(II) ion in the cyclam complex is six-coordinated within a distorted N(4)O(2) octa-hedral geometry, with the four cyclam N atoms in the equatorial plane and the two water mol-ecules in apical positions. The six-membered metalla ring adopts a chair conformation, whereas the five-membered ring exists in a twisted form. In the crystal packing, inter-molecular O-H⋯O hydrogen bonds between the water molecules and the carboxyl groups of the fumarate anions lead to the formation of layers with R(4) (2)(8) ring motifs. Ni(II) complex cations are sandwiched between two such layers, being held in place by O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, consolidating a three-dimensional network.

Poly[[diaqua-bis(μ(3)-maleato-κO:O,O:O)dicopper(II)] trihydrate].

Project description:In the title compound, {[Cu(2)(C(4)H(2)O(4))(2)(H(2)O)(2)]·3H(2)O}(n), Cu(II) ions with square-pyramidal coordination are bridged by exo-tri-dentate maleate dianions into [Cu(2)(maleate)(2)(H(2)O)(2)](n) layers coincident with the bc crystal plane. The inter-lamellar regions contain hydrogen-bonded cyclic water hexa-mers which facilitate layer stacking into a pseudo-three-dimensional crystal structure. The water hexamers themselves are formed by the operation of crystallographic inversion centers on sets of three crystallographically distinct water molecules of hydration.

Poly[tetra-μ-aqua-diaqua-tetra-kis-[μ-(E)-2-nitro-cinnamato]tetra-rubidium].

Project description:In the structure of the title compound, [Rb(4)(C(9)H(6)NO(4))(4)(H(2)O)(6)](n), the asymmetric unit comprises four rubidium cations, two of which have an RbO(7) coordination polyhedron with a monocapped distorted octa-hedral stereochemistry and two of which have a distorted RbO(6) octa-hedral coordination. The bonding about both the seven-coordinate cations is similar, comprising one monodentate water mol-ecule together with three bridging water mol-ecules and three carboxyl-ate O-atom donors, two of which are bridging. The environments around the six-coordinate cations are also similar, comprising a monodentate nitro O-atom donor, a bridging water mol-ecule and four bridging carboxyl-ate O-atom donors [overall Rb-O range = 2.849 (2)-3.190 (2) Å]. The coordination leads to a two-dimensional polymeric structure extending parallel to (001), which is stabilized by inter-layer water O-H⋯O hydrogen-bonding associations to water, carboxyl and nitro O-atom acceptors, together with weak inter-ring π-π inter-actions [minimum ring centroid-centroid separation = 3.5319 (19) Å].
