Catena-Poly[tetra-sodium [[cis-dioxido-trans-bis-(sulfato-?O)molybdate(VI)]-?-sulfato-?O:O']].

ABSTRACT: Single crystals of the title compound, {Na(4)[Mo(VI)O(2)(SO(4))(3)]}(n), were grown from a melt of MoO(3) and Na(2)SO(4) in Na(2)S(2)O(7). In contrast to the structure of the isoformular K compound, K(4)[Mo(VI)O(2)(SO(4))(3)], with its monomeric anion, this sodium analogue contains a polymeric anion of the type {[Mo(VI)O(2)(SO(4))(2)-?-(SO(4))](4-)}(n). The Mo(VI) cations, surrounded by two tightly bonded O atoms and four O atoms of one bridging and two terminal sulfato ligands, form zigzag chains parallel to [100]. All four Na(+) cations are situated between the anionic chains and have distorted octa-hedral coordination spheres.

Tripyridinium cis-tetra-chlorido-dioxido-molybdate(VI) chloride.

Project description:In the title compound, (C(5)H(6)N)(3)[MoCl(4)O(2)]Cl, the pyridinium cations are N-H?Cl hydrogen bonded to the anionic [MoCl(4)O(2)](2-) complexes and to the two crystallographically independent chloride anions (located on C2 axes). The Mo(6+) centre adopts a highly distorted octa-hedral geometry, being surrounded by four chloride and two terminal oxide groups. The oxide ligands are mutually cis.

Octa-rubidium di-?-sulfato-?O:O'-bis-[cis-dioxido-cis-disulfatotungstate(VI)].

Project description:The title compound, Rb(8)[W(2)O(4)(SO(4))(6)], was precipitated from a melt of tungsten(VI) oxide and rubidium sulfate in rubidium disulfate. The unit cell contains two discrete [{W(VI)O(2)(SO(4))(2)}(2)(?-SO(4))(2)](8-) units connected by Rb-O coord-ination. The W atom is octahedrally surrounded by two oxide ligands, two terminal sulfate ligands and two bridging sulfate groups. One Rb atom is coordinated by eight O atoms, whereas the three other Rb atoms are coordinated by nine O atoms from sulfate and oxide groups, leading to distorted [RbO(x)] polyhedra.

catena-Poly[sodium(I)-?-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.

Tetra-ammonium diaqua-diperoxidoocta-molybdate(VI) tetra-hydrate.

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. The clusters pack in a cubic close packing arrangement defining channels containing water mol-ecules and ammonium cations, which exhibit hydrogen bonding with neighbouring clusters. 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.

Bis(isopropyl-ammonium) tetra-sulfido-molybdate(VI).

Project description:The title compound, (C(3)H(10)N)(2)[MoS(4)], was synthesized by passing a rapid stream of H(2)S into an aqueous isopropyl-amine solution of molybdic acid. The title compound is isotypic with the corresponding W analogue (C(3)H(10)N)(2)[WS(4)]; its structure consists of a slightly distorted tetra-hedral [MoS(4)](2-) dianion and two crystallographically independent isopropyl-ammonium cations, with all atoms located in general positions. The cations and anion are linked by weak N-H⋯S and C-H⋯S inter-actions, the strength and number of which can explain the observed Mo-S bond distances.

catena-Poly[[[diaqua-(tetra-methyl-ethylenediamine-?(2) N,N')nickel(II)]-?-sulfato-?(2) O:O'] monohydrate].

Project description:The title compound, {[Ni(SO4)(C6H16N2)(H2O)2]·H2O} n , contains a Ni(II) atom that is coordinated nearly octa-hedrally by a chelating tetra-ethyl-enediamine (tmeda) ligand, two water mol-ecules in a cis arrangement and two O atoms of two sulfate anions in a trans arrangement. The sulfate anions act as ?2-bridging ligands leading to a chain structure of alternating NiO4N2 octa-hedra and SO4 tetra-hedra parallel to [001]. The polymeric chains are linked by O-H?O hydrogen bonds between coordinating water mol-ecules and sulfate anions to give double strands. There is a lattice water mol-ecule which is also involved in O-H?O hydrogen bonding between adjacent [Ni(SO4)(tmeda)(H2O)2] chains.

catena-Poly[[[tetra-kis-(4-methyl-pyridine-κN)copper(II)]-μ-sulfato-κO:O'] 4.393-hydrate].

Project description:The structure of the title compound, {[Cu(SO(4))(C(6)H(7)N)(4)]·4.393H(2)O}(n), consists of Cu(2+) ions surrounded in a square-planar fashion by 4-methyl-pyridine ligands, forming two crystallographically independent Cu{H(3)C(C(5)H(4)N)}(4) units that are both located on crystallographic inversion centers. The Cu(4-methyl-pyridine)(4) units are, in turn, connected with each other via bridging sulfate anions, leading to the formation of infinite [Cu{H(3)C(C(5)H(4)N)}(4)SO(4)](n) zigzag chains along [001]. The completed coordination spheres of the Cu(2+) ions are slightly distorted octa-hedral. The axial Cu-O bonds are elongated [average length = 2.42 (4) Å] compared to the equatorial Cu-N bonds [average length = 2.043 (2) Å]. The inter-stitial space between the chains is filled with uncoordinated water mol-ecules that consolidate the structure through O-H⋯O hydrogen bonding. One of the five crystallographically independent solvent water mol-ecules is partially occupied with an occupancy factor of 0.396 (4). Due to hydrogen bonding between symmetry-equivalent water mol-ecules across inversion centers, several of the water H atoms are disordered in 1:1 ratios over mutually exclusive positions. The crystal under investigation was found to be non-merohedrally twinned in a 0.789 (1):0.211 (1) ratio by a 180° rotation around the reciprocal b axis.

Tetra-pyridinium ?-oxido-di-?-sulfato-bis-[chloridodioxidomolybdate(VI)].

Project description:The title salt, (C(5)H(6)N)(4)[Mo(2)Cl(2)O(5)(SO(4))(2)], comprises four pyridinium cations for each [(MoClO(2))(2)(?-O)(?-SO(4))(2)](4-) anionic unit. The asymmetric unit consists of three aggregates of the empirical formula. The tetra-anionic bimetallic molybdenum(VI) cluster is unprecedented and contains two sulfate and one oxide bridges. This structure constitutes the first example of a non-polymeric compound with terminal oxide, sulfate and halide ligands bonded to the same metal. The hydrogen bonds connecting the pyridinium cations to the molybdenum clusters are diverse, varying from strong and directional interactions to bifurcated bonds with a subsequent loss of directionality.

catena-Poly[[bis-(ethyl-enediamine)copper(II)]-?-sulfato].

Project description:In the title compound, [Cu(SO(4))(C(2)H(8)N(2))(2)](n), the Cu, S and two O atoms lie on a mirror plane. The Cu atom is in a distorted octa-hedral environment and the ethyl-enediamine ligand is in a gauche conformation. The sulfate dianion is bridging, forming a one-dimensional chain. A two-dimensional net parallel to (001) is generated by N-H?O hydrogen bonding between the chains.
