Crystal structure of an ordered [WOF5]- salt: (1,10-phen-H)[WOF5] (1,10-phen = 1,10-phenanthroline).

ABSTRACT: Crystals of 1,10-phenanthrolinium penta-fluorido-oxidotungstate(VI), (1,10-phen-H)[WOF5] (1,10-phen = 1,10-phenanthroline, C12H8N2), were obtained upon hydrolysis of WF6(1,10-phen) in CH3CN at 193?K. The (1,10-phen-H)[WOF5] salt contains a rare example of a [WOF5]- anion in which the oxygen and fluorine atoms are ordered. This ordering was verified by bond-valence determinations and structural comparisons with [Xe2F11][WOF5] and Lewis acid-base adducts of WOF4 with main-group donor ligands. The crystal packing is controlled by N-H?F hydrogen bonding that is directed exclusively to the axial F atom as a result of its increased basicity caused by the trans influence of the oxido ligand.

Crystal structure of 11-[4-(hex-yloxy)phen-yl]-1,2,4-triazolo[4,3-a][1,10]phenanthroline.

Project description:The title compound, C25H24N4O, was prepared from 2-chloro-phenanthroline and hexyl-oxyphenyl-tetra-zole. The main difference between the two independent mol-ecules (A and B) in the asymmetric unit is the orientation of the all-anti-configured hex-yloxy chain: in A the C-O-C-C torsion angle is 175.9 (2)° whereas it is -88.3 (3)° in B. The benzene substitution in the bay of the triazolophenanthroline results in a helical distorsion of the heterocyclic core, the dihedral angles between the mean planes formed by quinoline and benzotriazole ring systems are 13.73 (9) for mol-ecule A and 14.87 (8)° for B. The dihedral angles between the triazole ring and the attached benzene ring are 45.87 (15) in A and 53.93 (14)° in B. The angular annulation of four rings and the benzene substituent results in a helical distortion of the aromatic framework. The crystal is formed from layers composed of centrosymmetric pairs of A 2, B 2 mol-ecules with inter-digitating alkyl chains.

2-(2,4,6-Trimethyl-phen-yl)-1,10-phenanthroline.

Project description:In the title mol-ecule, C(21)H(18)N(2), the mean plane of the benzene ring of the mesityl group forms a dihedral angle of 82.69 (4)° with that of the phenanthroline ring system. The crystal structure is stabilized by π-π stacking inter-actions between the phenanthroline system and the benzene ring of the mesityl group of a symmetry-related mol-ecule, with centroid-centroid distances of 3.7776 (14) and 3.7155 (13) Å.

Palladium(II) complexes of 1,10-phenanthroline: Synthesis and X-ray crystal structure determination.

Project description:Two palladium(II) complexes, [Pd(phen)(N identical withCCH(3))(2)][O(3)SCF(3)](2) (1) and [Pd(phen)(mu-OH)](2)[O(3)SCF(3)](2).2H(2)O (2) (where phen= 1,10-phenanthroline), have been crystallized following the reaction of Pd(phen)Cl(2) with silver triflate, Ag(O(3)SCF(3)), in acetonitrile and water, respectively. The structures of both complexes are based on a Pd(phen)(2+) metal core, with two acetonitrile molecules binding in a monodentate fashion in complex 1 and two hydroxo bridges holding together two cores to form a dimer in complex 2. Additionally, both complexes present a hydrogen bonded 3-D network involving the triflate anions in 1, and water and triflate anions in 2. Both complexes have been characterized by infrared and (1)H NMR spectroscopy and their crystal structures determined by X-ray crystallography.

Project description:The mol-ecule of the title compound, C(22)H(12)N(4)S(2), shows no crystallographic symmetry.

Project description:There are two formula units in the asymmetric unit of the title compound, C(21)H(17)N(5)·1.5H(2)O.
