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

ABSTRACT: 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.

Ammonium tris-(tetra-ethyl-ammonium) hexa-cosa-oxidoocta-molybdate.

Project description:The structure of the title compound, NH(4)(C(8)H(20)N)(3)[Mo(8)O(26)], is built up by discrete cations and anions, with two formula units in the asymmetric unit. The ?-octa-molybdate anions are linked to the ammonium cations via N-H?O hydrogen bonding involving terminal oxide groups and to the tetra-ethyl-ammonium cations via weak C-H?O inter-actions.

Redetermination of hexa-sodium hepta-molybdate(VI) 14-hydrate.

Project description:The structure of the title compound, Na(6)(Mo(7)O(24))·14H(2)O, has been redetermined [Sjöbom & Hedman (1973). Acta Chem. Scand.27, 3673-3674] and the hydrogen atoms have been located. The Na(+) cations adopt distorted octa-hedral geometries and the structure of the [Mo(7)O(24)](6-) anion is consistent with those of other hepta-molbydates. In the crystal, numerous O-H?O hydrogen bonds help to establish the packing.

Bis(trimethyl-phenyl-ammonium) ?-oxalato-bis-[oxidodiperoxido-molybdate(VI)].

Project description:A trimethyl-phenyl-ammonium salt of a dinuclear ?-oxalate complex of diperoxidomonomolybdate units, (C9H14N)2[Mo2(C2O4)(O2)4O2], was obtained from an acidic aqueous solution; the dianion is located about a centre of inversion. Each Mo atom bears two peroxide groups together with one O atom from the oxalate group in its equatorial positions and one terminal O atom as well as another O atom from the oxalate in axial positions. The oxalate group acts as a tetra-dentate bridging ligand and bridges between the diperoxidomolybdate units.

Tetra-kis(2-methyl-benzimidazolium) ?-octa-molybdate(VI).

Project description:The asymmetric unit of the title compound, (C(8)H(9)N(2))(4)[Mo(8)O(26)], consists of two 2-methyl-benzimidazolium cations and one-half of a ?-Mo(8)O(26) (4-) anion, which is completed by crystallographic inversion symmetry. An extensive net of N-H?O hydrogen bonds between the cations and anions contribute to the crystal packing.

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.

Tetra-ethyl-ammonium l-malate 1.36-hydrate.

Project description:The asymmetric unit of the title compound, C(8)H(20)N(+)·C(4)H(5)O(5) (-)·1.36H(2)O, contains two independent ion pairs, with similar conformations, and three water mol-ecules of crystallization, one water mol-ecule haing a site-occupancy factor of 0.721 (5). Intra-molecular O-H⋯O hydrogen bonds, involving the hydr-oxy groups and an O atom of each carboxyl-ate anion, generate five-membered rings involving S(5) ring motifs. In the crystal structure, mol-ecules are linked together by water mol-ecules through four-membered O-H⋯O-H⋯O-H inter-actions to form one-dimensional infinite chains along the a axis. Since the mol-ecules are also linked into one-dimensional infinite chains along the b axis, mol-ecular sheets parallel to the (001) plane are created. Overall, the crystal structure is stabilized by two intra-molecular O-H⋯O hydrogen bonds, nine inter-molecular O-H⋯O and ten C-H⋯O hydrogen bonds.

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.

Bis(methyl-ammonium) tetra-sulfido-tungstate(VI).

Project description:The title compound, (CH(6)N)(2)[WS(4)], was synthesized by the reaction of ammonium tetra-sulfidotungstate(VI) with aqueous methyl-amine. The title compound is isotypic with the corresponding Mo analogue (CH(6)N)(2)[MoS(4)], and its structure consists of a slightly distorted tetra-hedral [WS(4)](2-) dianion and two crystallographically independent methyl-ammonium (MeNH(3)) cations, all of which are located on crystallographic mirror planes. The tetra-sulfidotungstate anions are linked to the organic cations via hydrogen-bonding inter-actions.

Project description:Phase VI of bis-(tetra-methyl-ammonium) tetra-chloro-zincate(II), (C(4)H(12)N)(2)[ZnCl(4)], contains three formula units per asymmetric unit. Several short C-H⋯Cl contacts [2.70 (3) and 2.72 (4) Å] are observed, but they are believed to participate only in van der Waals inter-actions. The crystal studied exhibited inversion twinning.
