Poly[[(acetonitrile)-lithium(I)]-?(3)-tetra-fluoridoborato].

ABSTRACT: The structure of the title compound, [Li(BF(4))(CH(3)CN)](n), consists of a layered arrangement parallel to (100) in which the Li(+) cations are coordinated by three F atoms from three tetra-fluoridoborate (BF(4) (-)) anions and an N atom from an acetonitrile mol-ecule. The BF(4) (-) anion is coordinated to three different Li(+) cations though three F atoms. The structure can be described as being built from vertex-shared BF(4) and LiF(3)(NCCH(3)) tetra-hedra. These tetra-hedra reside around a crystallographic inversion center and form 8-membered rings.

catena-Poly[[tetra-aqua-μ-aqua-bis-(μ(4)-pyrimidine-2-carboxyl-ato)tetra-lithium] dichloride].

Project description:The asymmetric unit of the title compound, [Li(4)(C(5)H(3)N(2)O(2))(2)(H(2)O)(5)]Cl(2), contains two Li(I) cations, one with a distorted trigonal-bipyramidal and the other with a distorted tetra-hedral coordination geometry. Two symmetry-related asymmetric units constitute a building block of the structure, in which both ligand carboxyl-ate O atoms are bidentate and bridge the metal ions, forming a divalent cation. Charge balance is maintained by two chloride anions. The building blocks, bridged by Li(I) cations, form cationic ribbons with chloride anions in the space between them. The ribbons propagate in [010] and are held together by a network of weak O-H⋯O hydrogen bonds which operate in the space between adjacent ribbons.

Tetra-kis(acetonitrile-?N)lithium hexa-fluoridophosphate acetonitrile monosolvate.

Project description:In the title compound, [Li(CH(3)CN)(4)]PF(6)·CH(3)CN, the asymmetric unit consists of three independent tetra-hedral [Li(CH(3)CN)(4)](+) cations, three uncoordinated PF(6) (-) anions and three uncoordinated CH(3)CN solvent mol-ecules. The three anions are disordered over two sites through a rotation along one of the F-P-F axes. The relative occupancies of the two sites for the F atoms are 0.643?(16):0.357?(16), 0.677?(10):0.323?(10) and 0.723?(13):0.277?(13). The crystal used was a racemic twin, with approximately equal twin components.

Project description:The title chain polymer compound, [GaLi(2)Br(C(3)H(9)OSi)(4)(C(4)H(8)O)(2)](n), was obtained in the reaction of GaBr(3) with Me(3)SiOLi in toluene/tetra-hydro-furan. The Ga(III) atom, located on a twofold rotation axis, is coordinated by four trimethyl-silanolate ligands and has a distorted tetra-hedral geometry. The Li(I) atom is four coordinated by one bridging Br atom located on an inversion centre, two trimethyl-silanolate ligands and one tetra-hydro-furane mol-ecule in a distorted tetra-hedral geometry. The polymeric chains extend along [001]. The tetra-hydro-furane mol-ecule is disordered over two positions with site-occupancy factors of 0.57 (2) and 0.43 (2).

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].

catena-Poly[[[(triphenyl-phosphane)copper(I)]-di-μ-iodido-[(triphenyl-phosphane)copper(I)]-μ-[3,6-bis-(4-pyrid-yl)-1,2,4,5-tetra-zine]] acetonitrile disolvate].

Project description:The title compound, {[Cu(2)I(2)(C(12)H(8)N(6))(C(18)H(15)P)(2)]·2CH(3)CN}(n), contains centrosymmetric dinuclear Cu(2)I(2)(PPh(3))(2) units bridged by 3,6-bis-(4-pyrid-yl)-1,2,4,5-tetra-zine ligands lying also across crystallographic inversion centers, giving a chain structure in the ab plane. The distorted tetra-hedral Cu(I) atoms in the dinuclear unit are coordinated by two bridging iodide anions, one pyridine N atom from the substituted tetra-zine ligand and one terminal triphenyl-phosphine P-atom donor. The Cu⋯Cu distance is 2.8293 (12) Å, implying a weak Cu⋯Cu inter-action.

Poly[(μ-benzene-1,2,4,5-tetra-carboxyl-ato)tetra-silver(I)].

Project description:In the centrosymmetric title compound, [Ag(4)(C(10)H(2)O(8))](n), the benzene ring has irregular bond lengths but remains planar (r.m.s. deviation 0.0002 Å). The Ag-O bond lengths are in the range 2.153 (3)-2.615 (4) Å. The carboxyl-ate groups are oriented at dihedral angles of 26.4 (5) and 74.9 (4)° to the benzene ring. The coordination behaviour of each carboxyl-ate O atom is different: in one carboxylate, the O atoms are coordinated to a single and two Ag atoms; in the other carboxylate, the O atoms are coordinated to two and three Ag atoms. Non-classical inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure. The title compound forms a three-dimensional polymeric network due to the coordination of the Ag atoms.

Poly[μ(2)-aqua-μ(2)-(pyrazine-2-carboxyl-ato)-lithium].

Project description:The structure of the title compound, [Li(C(5)H(3)N(2)O(2))(H(2)O)](n), contains an Li(I) ion with a distorted trigonal-bipyramidal coordination environment involving the N and O atoms of pyrazine-2-carboxyl-ate ligands with a bridging carboxyl-ate group, and two aqua O atoms also in a bridging mode. The symmetry-related Li(I) ions bridged by a carboxyl-ate O atom and a coordinating water O atom form an Li(2)O(2) unit with an Li⋯Li distance of 3.052 (4) Å, which generates mol-ecular ribbons propagating in the c-axis direction. The ribbons are held together by a network of O-H⋯O hydrogen bonds in which the coordinating water mol-ecules act as donors and the carboxyl-ate O atoms as acceptors.

catena-Poly[sodium(I)-μ-tetra-butoxy-borato].

Project description:The title compound, [Na(C(16)H(36)BO(4))](n), has a fourfold axis passing through the Na and B atoms which both are bound by four O atoms. The tetra-butoxy-borate anion provides the bridging to form one-dimensional polymers running along [001], just like those found for the tetra-ethoxy-borate structure. The two but-oxy 'tail' atoms are disordered over two conformations in a 0.887 (9):0.113 (9) ratio.

Poly[[[tetra-aqua-cobalt(II)]-μ-bipyridine] terephthalate].

Project description:The Co(II) atom in the title complex, {[Co(C(10)H(8)N(2))(H(2)O)(4)](C(8)H(4)O(4))}(n), is coordinated by two N atoms of two bipyridine ligands and four O atoms of four water mol-ecules in an octahedral geometry. The one-dimensional [Co(C(10)H(8)N(2))(H(2)O)(4)](2+) cation chain is further extended into a supra-molecular network via O-H⋯O hydrogen-bond inter-actions. The Co atom lies on a twofold rotation axis; another twofold rotation axis passes through the carboxylate carbon atoms and the attached ring C atoms.

Poly[diaqua-μ(4)-oxalato-di-μ(6)-phosphato-tetra-cobalt(II)].

Project description:In the structure of the title compound, [Co(4)(C(2)O(4))(PO(4))(2)(H(2)O)(2)](n), there are layers composed of the phosphate anions and two independent Co(II) cations. These layers are parallel to (001) and are bridged by the oxalate anions that are situated in special positions on centres of symmetry. One independent Co atom has an octa-hedral coordination, while the second independent Co atom is coordinated in a trigonal-bipyramidal coordination that includes the water mol-ecule. The crystal packing is stabilized by O-H⋯O hydrogen bonds between the coordinated water mol-ecules and oxalate O atoms.
