5,6-Dihydro-1,10-phenanthroline-1,10-diium ?-oxido-bis-[penta-fluoridotantalate(V)].

ABSTRACT: In the title compound, (C(12)H(12)N(2))[Ta(2)F(10)O], the doubly protonated 5,6-dihydro-1,10-phenantroline-1,10-diium cation is located on a twofold rotation axis, whereas the isolated [Ta(2)OF(10)](2-) dianion has -1 symmetry. In the so far unknown dianion, the symmetry-related Ta(V) atoms are octa-hedrally coordinated by five F atoms and a bridging O atom, the latter being located on an inversion centre. The two pyridine rings in the cation make a dihedral angle of 22.8?(4)°. The cations and dianions are arranged in layers parallel to (100) and are connected through N-H?F and C-H?F hydrogen-bonding inter-actions into a three-dimensional structure.

Project description:In the structure of the title compound, [Ag(C(12)H(6)N(2)O(2))(2)]BF(4) or [AgL(2)]BF(4) (L = phendione), the Ag and B atoms are located on twofold rotation axes. The dihedral angle between the two phendione ligands is 36.7 (2)°. The coordination about the Ag(I) center is distorted tetra-hedral (τ(4) = 0.546). The crystal structure is consolidated by weak C-H⋯O(phendione) and C-H⋯F(BF(4) (-)) inter-actions. The BF(4) (-) counter-anion is strongly disordered and was modelled with two sets of idealized F atoms.

Bis[bis-(1,10-phenanthroline-?N,N')copper(I)] ?(6)-oxido-dodeca-kis-?(2)-oxido-hexa-oxidohexa-tungsten(VI).

Project description:The title compound, [Cu(C(12)H(8)N(2))(2)](2)[W(6)O(19)], consists of two [Cu(phen)(2)](+) cations (phen = 1,10-phenanthroline) and one typical [W(6)O(19)](2-) isopolyanion. The Cu(I) atom is coordinated by four N atoms from two bidentate chelating phen ligands in a distorted tetra-hedral geometry. The hexa-tungstate anion, lying on an inversion center and possessing the well known Lindqvist structure, is formed by six edge-sharing WO(6) octa-hedra, thus exhibiting an approximate O(h) symmetry. Three kinds of O atoms exist in the hexa-tungstate, viz. terminal O(a), bridging O(b) and central O(c) atoms. Besides the electrostatic effects between the anions and cations, weak C-H?O hydrogen bonds exist between the phen ligands and O(a) or O(b) atoms. The mean inter-planar distances of 3.485?(1) and 3.344?(1)?Å indicate ?-? stacking inter-actions between neighboring phen ligands. These weak hydrogen bonds and ?-? stacking inter-actions lead to a two-dimensional network.
